Using Upgrade Kit Number...

You must use an adapter kit to use ONline modules in the CoreBuilder 5000 Integrated System Hub. Once you install the adapter kit, ONline modules use most CoreBuilder 5000 Integrated System Hub capabilities, including:

■ Greater power availability

■ Extended monitoring

■ Extended manageability

■ Enhanced overall hub fault-tolerance

■ PacketChannel Backplane

CoreBuilder 5000 Intelligent Cooling Subsystem

For more information on the adapter kit, refer to Chapter 5, the section titled ONline Adapter Kits.

Some CoreBuilder 5000 features, such as a user interface to Controller-based power management functionality, are only available if a CoreBuilder 5000 Distributed Management Module (DMM) is installed in the CoreBuilder 5000 hub. For example, the user can only take control of power management (assign a power class to an installed CoreBuilder 5000 module) by entering CoreBuilder 5000 power management commands at the CoreBuilder 5000 terminal prompt.

CAUTION: Do not install an ONline Controller Module in the CoreBuilder 5000 Integrated System Hub.

The default temperature threshold is the maximum internal hub temperature for normal hub operation.

■ The allowable ambient temperature operating range is 0 °C to 50 °C (32 °F

to 122 °F).

■ An overheat condition exists when internal hub temperature exceeds the

default temperature threshold.

■ The default internal operating temperature threshold for the

CoreBuilder 5000 Integrated System Hub is 60 °C (140 °F) or higher.

1-8 INTRODUCTION

The Intelligent Cooling Subsystem in the CoreBuilder 5000 Integrated System Hub helps prevent:

■ Damage to the hub and all installed modules

■ Loss of configuration information

This section describes:

■ Active Controller Module Fan Indicators

■ Automatic CoreBuilder 5000 Module Power-Down

■ Enabling and Disabling CoreBuilder 5000 Module Power-Down

■ Active Controller Module Temp Indicators

Active Controller

Module Fan Indicators

Automatic

CoreBuilder 5000

Module Power-Down

Active Controller Module Fan indicators (LEDs or character display, depending on Controller Module model) indicate that an installed fan has failed. CoreBuilder 5000 17-slot and 10-slot hubs can temporarily run with two functioning fans. The CoreBuilder 5000 7-slot hub has only two functioning fans.

If one fan fails on a CoreBuilder 5000 7-slot Hub only, 3Com recommends that you replace the fan within 48 hours of failure notification or contact your service representative (refer to Appendix C, Maintenance).

Because the hub can run on just two fans, a warning provided by Active Controller Module Fan indicators allows you adequate time to replace a faulty fan at your convenience. For more information, refer to Chapter 7, Troubleshooting.

Operate the hub with all fans running.

The Intelligent Cooling Subsystem operates as follows:

1 Active and Standby Controller Modules continually monitor the temperature

sensor located behind each fan unit, providing an accurate measurement of internal hub temperature.

2 If the Distributed Management Module (DMM) command SET POWER

OVERHEAT_AUTO_POWER_DOWN MODE ENABLE is in effect, an overheat condition may cause installed Controller Modules to power down selected CoreBuilder 5000 modules. This condition continues until the cause of the overheat condition is corrected and normal hub internal operating temperature is restored.

The order in which CoreBuilder 5000 modules power down is determined by:

■ Individual CoreBuilder 5000 module power class settings

■ Relative slot location of each installed CoreBuilder 5000 module

For more information, refer to Chapter 4, the section titled Managing Power in the Hub.

CoreBuilder 5000 Intelligent Cooling Subsystem 1-9

Enabling and Disabling

CoreBuilder 5000

Module Power-Down

Active Controller

Module Temp Indicators

To enable or disable automatic power-down of CoreBuilder 5000 modules caused by a hub overheat condition, issue the SET POWER OVERHEAT_AUTO_POWER_DOWN MODE ENABLE (or DISABLE) command.

The default state is SET POWER OVERHEAT_AUTO_POWER_DOWN MODE DISABLE, meaning that installed CoreBuilder 5000 modules do not power down automatically during an overheat condition. For more information on overheat conditions, refer to Chapter 2, the section titled Overheat Conditions.

The SET POWER OVERHEAT_AUTO_POWER_DOWN MODE command is only available if you are using a Master DMM (indicated by RDY on the LCD display of a DMM that has Mastership status). For a discussion of Master Management Module functionality in the CoreBuilder 5000 Integrated System Hub, refer to Chapter 2, Theory of Operation, the section titled Mastership in the CoreBuilder 5000 Integrated System Hub.

The Temp indicator (LED or character display, depending on Controller Module model) on the Active Controller Module warns you in the case of internal overheat condition.

When hub internal operating temperature rises above the temperature threshold, the following occurs:

1 A built-in temperature sensor detects the rise in hub internal operating

temperature.

2 The Fault-Tolerant Controller Module Temp LED blinks and the Master DMM

character display (for DMM Version v3.0 and later) shows the word TEMP.

3 The Active Controller Module sends an alert to the system administrator using

the Master Distributed Management Module (if installed).

The overheat indication stops when hub internal operating temperature falls below the temperature threshold for at least 15 minutes. Correct the overheat condition promptly to avoid possible hardware damage. (Only the Active Controller Module indicators report hub operating conditions.)

Distributed Hub Management Architecture

CoreBuilder 5000 DMM

Models

Distributed hub management is a whole-system approach in which software and hardware management functions are shared among functionally related components. This design assures optimal fault-tolerance for the CoreBuilder 5000 Integrated System Hub and all of the modules within it.

CoreBuilder 5000 Integrated System Hub network management architecture enables you to manage multiple LAN segments from a single module. This capability is managed through:

■ CoreBuilder 5000 Distributed Management Module (DMM or DMM-EC)

■ CoreBuilder 5000 Network Monitor Card (NMC)

■ CoreBuilder 5000 Advanced Ethernet Network Monitor Card (A-ENMC)

An Advanced Network Monitor Card is a high-performance daughter card when installed on a CoreBuilder 5000 Ethernet media module or the DMM-EC and provides high-speed, multi-segmented monitoring capabilities.

The CoreBuilder 5000 DMM is available in the following models:

■ Distributed Management Module (DMM, Model Number 6000M-MGT)

– The DMM consolidates media management for all media modules, regardless of network communications protocol, onto a single card.

■ Advanced DMM/Controller Module (Model Number 6000M-CMGT) –

The Advanced DMM/Controller Module provides DMM functions with performance enhancements, as well as hub controller functions, on a module that installs in one of the controller bay slots in the CoreBuilder 5000 Hub.

■ DMM with Ethernet Carrier (DMM-EC, Model Number 6106M-MGT) –

The DMM-EC provides DMM functions as well as supporting the attachment of up to six Ethernet Network Monitor Cards.

You can install a backup DMM for extra fault-tolerance. If a primary (Master) DMM fails, the backup (Standby) DMM becomes the Master DMM and learns the existing hub configuration.

Distributed Hub Management Architecture 1-11

The rapid changeover from a failed Master DMM to a Standby DMM (which becomes Master when the current Master DMM fails) occurs without causing any loss of data. Nodes can still communicate with each other, but the DMM interface is briefly unavailable during the changeover.

CoreBuilder 5000

Network Monitor Cards

A Network Monitor Card (NMC) is a circuit board that provides network connectivity and gathers and reports statistics to an installed DMM. Network Monitor Cards are optional. Install them only if you need to gather network statistics and for network connectivity support. The NMC includes the following features:

■ Can be physically attached (ENMC or A-ENMC only) to a CoreBuilder 5000

Ethernet Media Module, or to a CoreBuilder 5000 Distributed Management Module with Ethernet Carrier (DMM-EC) installed in the hub.

■ Can be physically attached (TR-NMC only) to a CoreBuilder 5000 Token Ring

Media Module.

■ Does not consume a slot of its own. Rather, an NMC is a submodule that

shares slots with the CoreBuilder 5000 Media Module or DMM-EC to which it is attached.

■ Monitors all activity on a network, gathering statistics and reporting them to

a protocol-independent CoreBuilder 5000 Distributed Management Module.

■ Communicates with an installed DMM using a high-speed management path

on the backplane, irrespective of the physical location of the NMC in the hub.

■ Can be switched from one ring or network segment to another one having

the same protocol. This makes it possible to monitor multiple Ethernet or multiple Token Ring networks, one at a time, using the same NMC. Switch an NMC to monitor local (isolated_x) networks as well as backplane networks when it is installed on the media module that the isolated_x network exists on.

■ Provides full fault-tolerance capability. If an NMC fails, you can switch a

second NMC of the same protocol to the network previously monitored by the failed NMC.

The network assignment of an installed Token Ring Network Monitor Card (TR-NMC) is not switchable after the TR-NMC is installed on a CoreBuilder 5000 Token Ring Passive Media Module or on a CoreBuilder 5000 Token Ring Active Per-Module Media Module. Under these circumstances, the network assignment of the installed TR-NMC is the same as the network assignment of the host media module to which the TR-NMC is attached.

rings to monitor.

2 Install one Network Monitor Card to gather statistics for each Ethernet segment

(CoreBuilder 5000 or ONline) or CoreBuilder 5000 ring you want to monitor.

Statistics Reporting Example

To gather statistics on one Token Ring network and two Ethernet networks, install:

■ 1 DMM to fully manage all networks. This DMM is the Master DMM.

■ 1 TR-NMC to gather statistics for the Token Ring network. Install one

TR-NMC per segment.

■ 2 ENMCs or 1 A-ENMC to gather statistics for the 2 Ethernet segments.

Install one ENMC per segment.

If two or more DMMs are installed in the same CoreBuilder 5000 hub, only one DMM is elected Master. All other DMMs in that hub are standby DMMs.

Table 2-2

and Table 2-3 list CoreBuilder 5000 and ONline management

capabilities in the CoreBuilder 5000 Integrated System Hub.

2-2 CHAPTER 2: THEORY OF OPERATION

Master Management Module

A Master Management Module is the management module that manages and controls the hub. The Master Management Module can be either a CoreBuilder 5000 Distributed Management Module or an ONline Management Module (see Ta bl e 2 -2

Master Distributed Management Module

A CoreBuilder 5000 Master Distributed Management Module (DMM) is the CoreBuilder 5000 Management Module that manages and controls the hub. It has the ability to fully manage hub conditions (for example, power management, enabling power to slots, and setting hub operating temperature parameters).

To take advantage of advanced DMM monitoring and configuration features, install at least one DMM per hub.

An CoreBuilder 5000 Master DMM configures and provides status reporting for:

■ CoreBuilder 5000 Ethernet Modules and ONline Ethernet Modules.

and Table 2-3).

■ If the Ethernet Network Monitor Card (ENMC) assigned to an ONline

Ethernet network (networks 1, 2, or 3) is installed on a Distributed Management Module with Ethernet Carrier (DMM-EC), you can gather full statistics for that ONline Ethernet network.

■ If the ENMC is installed on a CoreBuilder 5000 Ethernet Module, you can

gather limited ONline Ethernet statistics.

■ Installed CoreBuilder 5000 and ONline Token Ring Media Modules. A Master

DMM can fully monitor CoreBuilder 5000 Token Ring networks, but an ONline Token Ring Management Module (TRMM) is required to monitor ONline Token Ring networks.

■ Installed ONline FDDI Media Modules. A Master DMM also gathers limited

ONline FDDI LAN statistics. An FDDI Management Module (FMM) is required to gather full FDDI LAN statistics for ONline FDDI networks.

■ A Master CoreBuilder 5000 Distributed Management Module (DMM):

■ Monitors CoreBuilder 5000 networks and ONline Ethernet networks.

■ Requires a protocol-specific Network Monitor Card to monitor any

network. You can install Ethernet Network Monitor Cards on any CoreBuilder 5000 Ethernet Media Module or on any CoreBuilder 5000 DMM-EC. You can only install Token Ring Network Monitor Cards on CoreBuilder 5000 Token Ring Media Modules.

■ Incorporates an LCD display that shows RDY to indicate this is the Master

DMM.

■ Has limited control on ATM modules that are managed by the ATM

Control Point and Switch Module. A DMM has power management and inventory management capabilities on ATM modules.

Management Capabilities 2-3

Standby Distributed Management Module

A Standby Distributed Management Module (DMM):

■ Is any installed DMM that does not have mastership. The LCD display on a

Standby DMM shows STBY.

■ Is inactive until the Master DMM fails.

■ Cannot monitor any network. A Standby DMM does not communicate with

installed Network Monitor Cards.

Master ONline Management Module

A Master ONline Management Module:

■ Has more limited hub management capabilities.

■ Configures and provides status reporting for all installed ONline modules.

■ Monitors the ONline network to which it is assigned.

ONline modules monitor the following with or without mastership:

■ An ONline Ethernet Management Module monitors the ONline Ethernet

network to which it is assigned.

ONline Master

Management Module

Status Display

■ An ONline Token Ring Management Module monitors the ONline Token

Ring network to which it is assigned.

■ An ONline FDDI Management Module monitors the ONline FDDI network to

which it is assigned.

A DMM and any ONline Management Module (EMM, TRMM, FMM) can coexist in the CoreBuilder 5000 Integrated System Hub with no loss of functionality. However, the DMM is always the Master Management Module in such cases.

ONline Master Management Modules display:

■ Limited CoreBuilder 5000 hub status information

■ Limited CoreBuilder 5000 module status information

■ Full status information for all installed ONline modules

The following considerations apply to the status display:

■ An ONline Master Management Module reports that the Active Controller

Module is installed in slot 17 (CoreBuilder 5000 Integrated System 17-slot hub) or in slot 10 (CoreBuilder 5000 Integrated System 10-slot hub) or in slot 7 (CoreBuilder 5000 Integrated System 7-slot hub).

■ An ONline Master Management Module does not report fan status.

■ The SET CONCENTRATOR PLATFORM command is disabled for all installed

ONline Management Modules because an ONline Management Module knows it is installed in a CoreBuilder 5000 Integrated System hub (the ONline Management Module must be Ethernet Version v4.0, Token Ring Version v2.1, and FMM Version v2.0 or later).

■ If you enter RESET POWER SUPPLY from an ONline Management Module

prompt, the ONline Management Module generates an error message.

2-4 CHAPTER 2: THEORY OF OPERATION

If you do not have the latest ONline Management Module software versions, obtain a software upgrade. To obtain help, refer to Appendix D for details.

Table 2-1

summarizes the CoreBuilder 5000 module and CoreBuilder 5000 hub

status information you can display with the following:

Module Configuration

When you install a DMM in a powered-on hub for the first time, and if that DMM is then elected Master:

■ The DMM automatically learns the configurations of all installed

CoreBuilder 5000 and ONline modules.

■ The DMM saves the configuration information it has learned in on-board

non-volatile RAM storage (NVRAM).

When you install an ONline EMM, TRMM, or FMM in a powered-on hub for the first time, and if it is then elected Master:

■ The ONline Master Management Module automatically learns the

configurations of all installed ONline modules.

■ The ONline Master Management Module then saves the learned

configuration in its NVRAM.

ONline Management Modules cannot save configurations for CoreBuilder 5000 modules.

You can configure any CoreBuilder 5000 module (except ATM modules) using a Master DMM, then install that hot-staged CoreBuilder 5000 module into another hub. This is possible because a CoreBuilder 5000 module stores configuration information in on-board non-volatile RAM (NVRAM).

Management Capabilities 2-5

ONline Module Configuration

When an ONline module powers on in a hub that is not managed:

■ The ONline module configures to DIP settings if the hub is already operating

when you install the ONline module.

■ The ONline module configures to DIP settings if the hub is not operating

when you install the ONline module (that is, if the hub powers on after you install the ONline module).

When an ONline module powers on in a managed hub:

■ If a saved configuration is not available for this type of ONline module

installed in this slot, the new ONline module configures to defaults (isolated, with all ports disabled).

■ For example, if you replace a faulty ONline BNC Module in slot 5 with a

functional ONline BNC Module installed in the same slot, and the Master Management Module does not have a saved configuration for the replacement ONline BNC Module, the replacement BNC Module configures to defaults.

The ONline module configures to defaults if the hub is already operating when you install the ONline module, or if the hub is not operating when you install the ONline module (that is, if the hub powers on after you install the ONline module).

■ If an installed Master DMM or Master ONline Management Module has a

saved configuration for this type of ONline module newly installed in this slot, the Master DMM or Master ONline Management Module provides the

saved configuration to the newly installed ONline module.

■ For example, if you replace a faulty ONline BNC Module in slot 5 with a

functional ONline BNC Module installed in the same slot, the Master Management Module provides a saved ONline BNC Module configuration (if available) to the replacement module.

The new ONline module configures to the saved configuration if the hub is already operating when you install the ONline module, or if the hub is not operating when you install the ONline module (that is, if the hub powers on after you install the ONline module).

The newly installed ONline module can be either a replacement module that has been configured in another hub, or a new module that has never been configured. If a usable saved configuration is not available, the new module stays in the default state.

Both DMMs and ONline Management Modules have a ’configure to DIPs’ option which allows media modules (ONline and CoreBuilder 5000) to configure to DIP switch settings automatically, regardless of the saved configuration that management might have for them.

2-6 CHAPTER 2: THEORY OF OPERATION

CoreBuilder 5000 Module Configuration

CoreBuilder 5000 modules can save their own configurations. Once installed, CoreBuilder 5000 modules first attempt to configure from either of the following settings:

■ On-board DIP switch settings

■ A saved configuration stored in on-board non-volatile memory (NVRAM)

For each CoreBuilder 5000 module, the switch setting (to DIP or to NVRAM) determines which configuration (DIP or NVRAM) is attempted.

If a Master DMM is present, the CoreBuilder 5000 module submits its configuration (DIP or stored in NVRAM) to a Master DMM for approval.

■ If the Master DMM has a saved configuration for the CoreBuilder 5000

■ If the Master DMM does not have a saved configuration for the

module, it provides that configuration to the CoreBuilder 5000 module, overriding the CoreBuilder 5000 module’s requested configuration.

CoreBuilder 5000 module, it allows the CoreBuilder 5000 module to configure to its requested configuration, provided the requested configuration is valid.

■ If the configuration requested by the CoreBuilder 5000 module has some

invalid settings, the CoreBuilder 5000 module reverts to defaults (isolated with all ports disabled).

If a Master DMM is not present and the CoreBuilder 5000 module is set to:

■ DIP settings, then the CoreBuilder 5000 module uses the DIP configuration.

■ NVRAM and the CoreBuilder 5000 module has a stored configuration, the

CoreBuilder 5000 module configures to that stored configuration.

■ NVRAM and no configuration is stored there, the CoreBuilder 5000 module

configures to defaults (isolated with all ports disabled).

■ NVRAM and the stored configuration is invalid, the CoreBuilder 5000 module

configures to defaults (isolated with all ports disabled).

Network Monitor Cards do not store a configuration in NVRAM. During a system reset in which all modules reboot, Network Monitor Cards set to defaults and wait to be configured by a Master DMM.

A DMM elected to mastership learns all configuration information for all installed modules (CoreBuilder 5000 and ONline), and automatically restores that information to all modules or their replacements following a hub or module failure.

Network Monitoring

and Module

Configuration Summary

Only a Distributed Management Module (DMM) elected to mastership has the ability to configure modules. A CoreBuilder 5000 or ONline Management Module not elected to mastership can only monitor the network to which it is assigned.

For further information about ONline Management Module functionality, refer to the ONline Network Management Module Installation and Operation Guide that describes the ONline Management Modules or ONline Media Modules you want to install.

Management Capabilities 2-9

Using Backup

Management Modules

You can provide extra protection for your system by installing backup management modules (two or more DMMs) in the hub. The Master DMM (Distributed Management Module) provides configurations to all modules. One or more additional DMMs back up the Master DMM if it fails.

■ Install more than one DMM-EC in your system to ensure that Ethernet

Network Monitor Cards (ENMC) or Advanced Ethernet Network Monitor Cards (A-ENMC) installed on multiple DMM-ECs provide full monitoring for a greater number of CoreBuilder 5000 and ONline Ethernet networks (each DMM-EC can support up to 6 ENMCs).

If you back up an A-ENMC with an ENMC, features (for example, the security feature) from the A-ENMC are not supported once the ENMC takes over. If you want A-ENMC full-feature functionality, then use another A-ENMC for the n + 1 redundancy function.

■ Assign an ENMC as a standby ENMC in order to establish fault-tolerance for

an active ENMC.

■ Install additional Ethernet Network Monitor Cards on CoreBuilder 5000

Ethernet Media Modules.

A CoreBuilder 5000 Distributed Management Module provides full network monitoring for ONline Ethernet Modules if the Ethernet Network Monitor Card you are using is installed on a DMM-EC (rather than on a CoreBuilder 5000 Ethernet Media Module).

■ Install all Ethernet Network Monitor Cards on 2 DMM-ECs (6 ENMCs per

DMM-EC) to monitor all of the hub’s 8 Ethernet segments. This installation approach centralizes the physical location of ENMCs in your hub and simplifies maintenance.

Backup Management Module Example

Ethernet Network Monitor Cards installed on a DMM-EC in standby mode are configured by the Master DMM to monitor Ethernet networks. When a DMM-EC is in standby mode, only the DMM (management) component of the DMM-EC is in standby mode. The Carrier component of the DMM-EC (the component that supports the attachment of ENMCs) remains active.

If you remove a host DMM-EC to replace a defective Ethernet Network Monitor Card, you can replace the faulty ENMC without disrupting port connections. However, if you remove an installed CoreBuilder 5000 Ethernet Media Module to replace a faulty Network Monitor Card, port connections are disrupted.

Controller Module

Functionality

This section describes:

■ Controller Module Models

■ Active and Standby Controller Module Functionality

■ Identifying Controller Module Slots

■ Downloading Software to the Controller Module

■ Controller Module Fault-Tolerance

The Controller Module is available in the following models:

■ Fault-Tolerant Controller Module (Model Number 6000M-RCTL) –

Provides all controller functions as described in this section.

■ Advanced DMM/Controller Module (Model Number 6000M-CMGT) –

Provides all controller functions as described in this section, as well as DMM functions with performance enhancements, on a module that installs in one of the controller bay slots in the CoreBuilder 5000 hub.

Installed Active and Standby Controller Modules provide power management for all installed CoreBuilder 5000 modules and maintain an accurate power budget for the hub.

■ The first Controller Module you install assumes the role of Active Controller

Module.

■ The second Controller Module you install assumes the role of Standby

Controller Module.

Active Controller Module

The Active Controller Module:

■ Monitors hub conditions

■ Provides clocking and timing to the backplane

■ Synchronizes the operation of all installed modules

In a managed hub, the Active Controller Module reports:

■ All hub operating conditions to the Master DMM (Distributed Management

Module)

■ Failures to the Master DMM

■ Limited information to the Master ONline Management Module

Standby Controller Module

The Standby Controller Module monitors hub conditions.

In a hub managed by a Master DMM (Distributed Management Module), you can use management commands to define power management parameters. For information on Controller-based power management functionality, refer to Chapter 4, the section titled Managing Power in the Hub.

CoreBuilder 5000 Controller Module Descriptions 2-11

The hub Controller Module bay accommodates up to two Controller Modules. Install at least one Controller Module for normal hub operation. Install a second Controller Module to achieve Controller Module fault-tolerance. For more information, refer to the section titled Controller Module Fault-Tolerance later in this chapter.

Downloading Software

to the Controller

Module

Future enhancements to Controller Module features may make it necessary to download a new revision of the software.

This section describes:

■ Downloading to a Hub Containing Two Installed Controller Modules

■ Downloading to a Hub Containing One Installed Controller Module

■ Download Status Display

To perform Controller Module download in all 10-slot hubs, DMM Version v2.0 or later must be installed.

Downloading to a Hub Containing Two Installed Controller Modules

If you download software to installed Controller Modules rather than Standby Controller Modules, download to the Standby Controller Module first. This causes only one disruption to hub operation.

The DMM may display irrelevant traps about an installed Controller Module after you download new Controller Module code.

In a hub containing two installed Controller Modules, always perform the download in this order:

1 Perform a download to the Standby Controller Module. 2 Perform a download to the Active Controller Module.

When you download to the Standby Controller Module first:

■ The Standby Controller Module remains in Standby mode and causes no

disruption to hub operation.

■ The Active Controller Module reboots, and then loses Active Controller

Module status to the Standby Controller Module. The Active Controller Module reboots and briefly disrupts hub operation.

CoreBuilder 5000 Controller Module Descriptions 2-13

A download to the Active Controller Module first would cause two disruptions to hub operation. Because it causes two disruptions (one more than necessary), this approach to download is possible but not recommended.

When you download to the Active Controller Module first:

■ The Active Controller Module reboots and loses Active Controller Module

status (the Standby Controller Module becomes the new Active Controller Module, and the old Active Controller Module becomes the Standby Controller Module).

This is the first disruption to hub operation.

■ A second disruption to hub operation occurs when you download to the

new Active Controller Module that was previously the Standby Controller

Module (a second reboot and swap of Active Controller Module status takes place).

Downloading to a Hub Containing One Installed Controller Module

In a hub containing only one installed Controller Module, the system recognizes the single installed Controller Module as the Active Controller Module.

You can perform a Controller Module software download when there is just one installed Controller Module, keeping in mind the following:

■ Power management functionality is inactive while a download is in progress,

and until the download completes.

■ If a power failure occurs while download is in progress, the system may not

be able to recover and the Controller Module to which you are downloading may fail.

■ Upon power recovery, replace the failed Controller Module and re-initiate

the download to the replacement Controller Module.

■ Next (optionally), re-insert the original Controller Module (the one that

failed during the first download) and re-initiate download to the original Controller Module while the Active Controller Module is present and functioning.

The original Controller Module powers on as the Standby Controller Module.

Download Status Display

As you perform a download to the Controller Module, the Controller Module front panel indicates download status.

■ On the Fault-Tolerant Controller Module (Model Number 6000M-RCTL), the

Temp LED lights and remains lit until the download completes. If the download attempt is unsuccessful, the STBY and Active LEDs light and remain lit until you re-initiate the download.

■ On the Advanced DMM/Controller Module (Model Number 6000M-CMGT),

the STBY and Active LEDs light and remain lit until the download completes. In addition, the character display on the Master DMM displays DNLD. To determine when the download is complete, check the DMM console output. The download should complete within 1 minute.

2-14 CHAPTER 2: THEORY OF OPERATION

Controller Module

Fault-Tolerance

Both the Active Controller Module and the Standby Controller Module monitor and modify hub operating conditions (such as power and temperature).

Redundant monitoring and control capability enables the Standby Controller Module to be ready to instantly take over for the Active Controller Module should the need arise. This capability is called fault-tolerance. Controller-based

fault-tolerance is highly recommended.

Installing Two Controller Modules into a Powered-on Hub

If two Controller Modules are installed in a hub that is already powered on:

■ The first Controller Module installed becomes the Active Controller Module.

■ The second Controller Module installed becomes the Standby Controller

Module.

Under these circumstances, the number of the slot in which a Controller Module is installed does not determine whether the module becomes the Active or Standby Controller Module.

Installing Two Controller Modules into a Powered-off Hub

If two Controller Modules are installed in a hub that is not yet powered on:

■ The Controller Module installed in slot 18 (17-slot hub) or in slot 11 (10-slot

hub) or in slot 8 (7-slot hub) always becomes the Active Controller Module when the hub is subsequently powered on.

■ If the hub is reset by a power outage or through CoreBuilder 5000 DMM

commands:

■ The Controller Module in slot 18 (17-slot hub) or slot 11

(CoreBuilder 5000 10-slot hub) or slot 8 (7-slot hub) becomes the Active Controller Module.

■ The Controller Module in slot 19 (17-slot hub) or slot 12

(CoreBuilder 5000 10-slot hub) or slot 9 (7-slot hub) becomes the Standby Controller Module.

Active Controller Module Limitation

Only one Controller Module can be the Active Controller Module at any given time. When only one Controller Module is installed, that Controller Module is the Active Controller Module.

CoreBuilder 5000 Controller Module Descriptions 2-15

Changing From Standby to Active Status

When the Standby Controller Module takes over for the Active Controller Module, all installed modules reboot (this type of reset is called ’fast reset’). To facilitate immediate resumption of hub activity following a reboot, CoreBuilder 5000 modules equipped with on-board non-volatile memory (NVRAM) automatically load the configuration stored in NVRAM. This occurs

regardless of current DIP switch settings.

In contrast to a fast reset, when a CoreBuilder 5000 module is cold booted, the CoreBuilder 5000 module configures from either DIP switches or from NVRAM storage. Cold boot is when a CoreBuilder 5000 module becomes power enabled by installed Controller Modules or following a hub reset. The DIP switch setting on each CoreBuilder 5000 module (to DIP settings or to NVRAM) determines how each CoreBuilder 5000 module configures. For more information, refer to the section titled CoreBuilder 5000 Module Configuration earlier in this chapter.

CAUTION: Double-fault scenarios in a mixed environment (CoreBuilder 5000 and ONline modules) may cause all CoreBuilder 5000 modules to power down. For example, a Controller Module switchover (fast reset) occurs, followed by a power supply failure within 30 seconds of the switchover. To recover from a double-fault scenario, power off the hub or remove any installed module. Upon poweron, installed Controller Modules assess the power budget. When the CoreBuilder 5000 modules previously powered off power on again, power configuration values set to factory defaults.

2-16 CHAPTER 2: THEORY OF OPERATION

CoreBuilder 5000 Module Poweron Strategy

Default

CoreBuilder 5000

Module Poweron

Strategy

This section describes:

■ Default CoreBuilder 5000 Module Poweron Strategy

■ Specifying CoreBuilder 5000 Module Poweron Order

The Controller Module determines how much power a CoreBuilder 5000 module requires before it permits the module to power on.

Controller Modules employ the following poweron strategy:

■ Current unallocated power budget must be sufficient to power on this

CoreBuilder 5000 module.

■ During hub poweron, installed Controller Modules power on the DMM that

has the highest power class setting of all installed DMMs before powering on all other installed CoreBuilder 5000 modules. This DMM is thereby elected Master.

■ CoreBuilder 5000 modules set to SLOT POWER ENABLED power on, in order,

from slot 1 to slot 17 (CoreBuilder 5000 Integrated System 17-slot hub) or from slot 1 to slot 10 (CoreBuilder 5000 Integrated System 10-slot hub) or from slot 1 to slot 7 (CoreBuilder 5000 Integrated System 7-slot hub).

■ CoreBuilder 5000 modules set to SLOT POWER ENABLED that have the

highest power class setting power on first.

■ CoreBuilder 5000 modules set to SLOT POWER ENABLED continue to power

on based on power class settings (from highest to lowest). This process continues until the limit of the power budget is reached.

■ If two or more CoreBuilder 5000 modules set to SLOT POWER ENABLED have

the same power class setting, they power on, in order, from slot 1 to slot 17 (CoreBuilder 5000 Integrated System 17-slot Hub) or from slot 1 to slot 10 (CoreBuilder 5000 Integrated System 10-slot Hub) or from slot 1 to slot 7 (CoreBuilder 5000 Integrated System 7-slot Hub).

■ CoreBuilder 5000 modules set to SLOT POWER DISABLED are not permitted

to power on.

Poweron occurs in this manner only if installed CoreBuilder 5000 modules do not configure from saved power management configuration data stored in their NVRAM. For more information, refer to Chapter 4, the section titled Saved Power Management Configurations.

CoreBuilder 5000 modules power off in response to an overheat condition that occurs only within affected overheat management areas. For information on overheat power on and power-down, refer to the section titled Overheat

Condition later in this chapter.

CoreBuilder 5000 Module Power-off Response 2-17

Specifying

CoreBuilder 5000

Module Poweron Order

CoreBuilder 5000 Module Power-off Response

To specify the order in which CoreBuilder 5000 modules power on, change their power class settings.

To change the power class setting for any CoreBuilder 5000 module:

1 Enter the SET POWER SLOT CLASS command. 2 Press Enter.

For further information, refer to the CoreBuilder 5000 Distributed Management Module Commands Guide.

Assign a high power class setting (for example, 9) to modules that provide network interfaces for a DMM (host CoreBuilder 5000 modules to which a Network Monitor Card is attached) to ensure that they receive power first and power off last. This approach also ensures that the DMM does not lose network connectivity and SNMP management of the hub during a power-off sequence.

This section describes how Intelligent Power Management responds to power deficits and overheat caused by selected abnormal operating conditions.

This section describes:

■ Correcting a Power Deficit

Correcting a Power

Deficit

■ Overheat Condition

To correct a power deficit, installed Controller Modules must reduce the power consumption of all installed modules. Controller Modules can only reduce power consumption by:

■ Disabling power fault-tolerant mode (if in effect) to make reserve power

available to installed modules.

■ Selectively powering off CoreBuilder 5000 modules to return power to the

budget.

Installed Controller Modules power off CoreBuilder 5000 modules the same way in:

■ An unmanaged hub

■ A hub managed by a Master DMM

■ A hub managed by a Master ONline Management Module

If installed Controller Modules are unable to respond to a power deficit (for example, due to a power failure), the hub resets. Under these conditions, poweron (recovery) occurs when the hub reboots.

For more information, refer to the section titled Power Supply Failure

later in

this chapter.

2-18 CHAPTER 2: THEORY OF OPERATION

Powering on With Insufficient Power

If there is insufficient power to power on:

■ A CoreBuilder 5000 module – Installed Controller Modules automatically

■ An ONline module – The ONline module draws power anyway.

Installed Controller Modules cannot reduce overall power consumption for a hub containing only ONline modules.

For more information, refer to the section titled ONline Module Power Deficit later in this chapter.

Power Supply Failure

Intelligent Power Management response to a power supply failure is determined by the current power mode:

■ If a power supply fails while the hub is running in power fault-tolerant

place the CoreBuilder 5000 module in power pending state until there is enough power to enable it.

mode:

■ Installed Controller Modules respond by disabling power fault-tolerant

mode. If the power budget deficit remains in effect after power fault-tolerant mode has been disabled, CoreBuilder 5000 modules selectively power off based on power class settings and relative slot locations until the power budget deficit is corrected.

■ Once the power budget deficit is corrected and there is again enough

power to re-establish power fault-tolerant mode, power fault-tolerant mode is automatically re-enabled.

When a power deficit occurs while the hub is running in power fault-tolerant mode, Controller Modules do not shut off CoreBuilder 5000 modules to reduce the power budget. For more information on power budget, refer to Chapter 4, Installing Power Supplies.

■ If a power supply fails while the hub is running in power non-fault-tolerant

mode (the default mode), installed Controller Modules may selectively shut off CoreBuilder 5000 modules in an attempt to bring module power consumption under budget.

The CoreBuilder 5000 module power-off sequence is as follows:

■ CoreBuilder 5000 modules power down, in order, from slot 17 to slot 1

(17-slot hub), from slot 10 to slot 1 (10-slot hub), or from slot 7 to slot 1 (7-slot hub), starting with CoreBuilder 5000 modules having the lowest power class setting.

■ If two or more CoreBuilder 5000 modules have the same power class, they

power off from slot 17 to slot 1 (17-slot hub, from slot 10 to slot 1 (CoreBuilder 5000 10-slot hub), or from slot 7 to slot 1 (7-slot hub).

■ CoreBuilder 5000 modules continue to power off until total power

consumption is at or below budget.

CoreBuilder 5000 Module Power-off Response 2-19

You can specify the order in which CoreBuilder 5000 modules power off when a power supply failure occurs by changing CoreBuilder 5000 module power class settings using the SET POWER command.

For more information, refer to the section titled Specifying CoreBuilder 5000 Module Poweron Order earlier in this chapter and the CoreBuilder 5000 Distributed Management Module Commands Guide.

For information on CoreBuilder 5000 module power-off due to an overheat condition, see the section titled Overheat Condition later in this chapter.

Even during a power deficit, a CoreBuilder 5000 module having a power class setting of 10 does not power off unless the user explicitly orders it to do so. To force a CoreBuilder 5000 module (except the Active Controller Module) to shut down, enter the SET POWER SLOT MODE DISABLE command at the prompt.

ONline Module Power Deficit

If ONline module installation causes a power deficit in power fault-tolerant mode or power non-fault-tolerant mode:

■ ONline modules do not power off automatically.

■ The Master DMM sends a power threshold trap warning of a power

utilization problem.

■ The hub remains in power deficit until it power cycles, or until you perform a

hub reset.

■ Installed Controller Modules power-enable CoreBuilder 5000 modules

according to their power class settings using the remaining power not consumed by ONline modules.

■ CoreBuilder 5000 modules are power-enabled only after all ONline modules

are powered on.

If the insertion of an ONline module causes a power deficit while the hub is running in power fault-tolerant mode:

■ Installed Controller Modules disable power fault-tolerance in an attempt to

eliminate the power deficit. This action makes power formerly held in reserve available to installed modules.

■ After the power deficit is corrected and there is again enough power to

re-establish power fault-tolerant mode, power fault-tolerant mode is automatically re-enabled.

Though the user cannot assign power class settings to ONline modules, an installed Master DMM does maintain a power consumption table that it uses to accurately assess the specific power requirements for any installed ONline module. This information enables installed Controller Modules to maintain an accurate picture of the power budget. For further details, refer to Appendix B, the section titled ONline Module Power Consumption.

For a complete list of ONline module power requirements (per module), refer to Appendix B, Voltages and Watts Consumed Per Module.

2-20 CHAPTER 2: THEORY OF OPERATION

If the insertion of an ONline module causes a power deficit while the hub is running in power non-fault-tolerant mode:

■ An installed Master DMM displays a warning that a power deficit now exists.

■ If you fail to correct the power deficit, the hub may shut down.

CAUTION: A newly installed ONline module may consume enough power to cause the hub to shut off before the Master DMM can re-assess the effect of the ONline module on unmanaged power allocation and notify installed Controller Modules to update the power budget accordingly. In a hub not managed by a Master DMM, you must calculate power consumption for installed modules before you install an ONline module that might erode the current power budget.

If you attempt to correct a power deficit by removing an ONline module from the hub:

■ Installed Controller Modules return the power formerly allocated to that

■ CoreBuilder 5000 modules in power pending state are then enabled to the

ONline module to the power budget.

limit of the available power budget.

Overheat Condition This section describes:

■ Overheat Conditions

■ Enabling and Disabling Automatic CoreBuilder 5000 Module Power-off

(Overheat Condition)

■ Overheat Management Areas

■ Overheat Power-off Process

■ Overheat Recovery Process

Overheat Conditions

An overheat condition exists when one of the hub temperature sensors detects a hub internal operating temperature that exceeds a pre-defined threshold. The allowable ambient temperature operating range is 0 °C to 50 °C. The default threshold setting is fixed at an upper limit of 60 °C (140 °F) or higher to prevent module damage.

An overheat condition may be caused by cooling loss or excessively high ambient (room) air temperature.

The following events occur during an overheat condition:

1 The Fault-Tolerant Controller Module Temp LED blinks and the Master DMM

character display (for DMM Version v3.0 and later) shows the word TEMP.

2 If an SNMP agent is present in the hub, power management informs the SNMP

agent of the overheat condition.

3 A 1-minute delay is provided, during which the Master DMM (Distributed

Management Module) and external management entities are notified of the overheat condition.

4 Approximately 1 minute later, Controller Modules apply a power-off strategy to

installed CoreBuilder 5000 modules in the overheat management areas where the overheat condition was detected.

5 The overheat indication (LED or character display) stops when the hub internal

operating temperature falls below the temperature threshold and stays there for 15 minutes.

Controller Modules do not power off CoreBuilder 5000 modules occupying slots outside affected overheat management areas. This overheat power-off strategy is based on the power class setting and slot location of each installed CoreBuilder 5000 module.

Enabling and Disabling Automatic CoreBuilder 5000 Module Power-off (Overheat Condition)

To enable automatic CoreBuilder 5000 module power-off in response to an overheat condition:

1 Enter the SET POWER OVERHEAT_AUTO_POWER_DOWN MODE ENABLE

command.

2 Press Enter.

To disable automatic CoreBuilder 5000 module power off in response to an overheat condition:

1 Enter the SET POWER OVERHEAT_AUTO_POWER_DOWN MODE DISABLE

command.

2 Press Enter.

ONline modules can never be automatically powered off by installed Controller Modules or (manually) by DMM commands entered at the prompt.

Overheat Management Areas

The overheat power-off process is based on three temperature sensors in the 17-slot and the 10-slot hub, one per installed fan unit, that effectively divide the module payload area of the hub into three overlapping overheat management

areas.

The CoreBuilder 5000 Integrated System 7-slot hub has one temperature sensor.

Each overheat management area comprises 8 payload slots. The overlap reflects the overlapping cooling effects of adjacent fan units (the hub can run with a minimum of 2 installed and functioning fan units, but 3 are recommended).

The overheat management areas divide the payload slots as follows:

■ Slots 1 through 8 (overheat management area 1)

■ Slots 6 through 13 (overheat management area 2)

■ Slots 10 through 17 (overheat management area 3)

This division does not apply to the CoreBuilder 5000 7-slot hub.

2-22 CHAPTER 2: THEORY OF OPERATION

Overheat Power-off Process

The CoreBuilder 5000 module overheat power-off process is as follows:

■ When any hub temperature sensor detects an internal hub operating

■ When internal hub operating temperature reaches 60 °C (140 °F), power

temperature of 45 °C or higher, power management issues warning traps that tell the user an overheat condition may soon exist. The system generates warning traps every 30 seconds (approximately) at this point.

management power-disables selected CoreBuilder 5000 modules installed within each affected overheat management area to reduce the 5 Volt power consumption by at least 50 Watts.

Selected CoreBuilder 5000 modules in affected overheat management areas power-down, in order, starting with CoreBuilder 5000 modules having the lowest power class setting.

This reduction of power consumption should provide a 2 °C

drop in

temperature per slot at the temperature sensor for that overheat management area. A single temperature sensor is located at the back of each exhaust fan. The system generates overheat traps every 10 seconds (approximately).

■ If two or more CoreBuilder 5000 modules in an affected overheat

management area have the same power class, they power off from highest slot to lowest slot.

■ CoreBuilder 5000 modules continue to power off until all CoreBuilder 5000

modules in the affected overheat management area have powered off or you resolve the overheating condition. CoreBuilder 5000 modules with a power class setting of 10 continue to run.

■ Hub temperature is allowed to stabilize for 15 minutes before further action

is taken.

■ If hub temperature is not at or below the established overheat threshold

after 15 minutes have elapsed, all CoreBuilder 5000 modules in the affected overheat management areas are powered down. CoreBuilder 5000 modules in affected overheat management areas do not power on again until you correct the overheat condition.

Overheat Recovery Process

Overheat recovery occurs when the temperature sensor that detected an overheat condition reports that internal hub temperature is at or below the overheat threshold.

Once overheat recovery is initiated, CoreBuilder 5000 modules that were powered off to alleviate the overheat condition power on to the limit of the current power budget.

CoreBuilder 5000 Module Power-off Response 2-23

Controller Modules perform overheat recovery poweron as follows:

■ CoreBuilder 5000 modules power on, in order, from the lowest slot in the

affected overheat management area to the highest slot in the affected overheat management area.

■ CoreBuilder 5000 modules with the highest power class setting power on

first. If two or more CoreBuilder 5000 modules have the same power class setting, they power on from the lowest slot in the affected overheat management area to the highest slot in the affected overheat management area.

CAUTION: If SET POWER OVERHEAT_AUTO_POWER_DOWN MODE DISABLE is in effect when an overheat condition occurs, the hub and all installed modules continue to run. Under these circumstances, an extended overheat condition may cause heat-related hardware damage. 3Com recommends that you run the hub with OVERHEAT_AUTO_POWER_DOWN MODE ENABLE in effect.

3-10 CHAPTER 3: INSTALLING THE HUB

Location Requirements A CoreBuilder 5000 Integrated System Hub must be installed in an area that

meets the following requirements:

■ Ambient (room) temperature: 0 °C to 50 °C (32 °F to 122 °F). The default

internal operating temperature threshold for the CoreBuilder 5000 Integrated System Hub is approximately 60 °C (140 °F).

■ Relative humidity: less than 95 percent, non-condensing.

■ AC or DC power source within 6 feet (approximately 1.8 meters).

■ Safety regulations stipulate that the table or rack on which the hub rests

should be able to support at least three times the weight of a fully loaded hub (for a 17-slot hub, 360 lbs. or 163 kg; for a 10-slot hub, 237 lbs. or

107.5 kg, 168 lbs. or 76.2 kg for a 7-slot hub).

■ A fully loaded CoreBuilder 5000 Integrated System 17-slot hub weighs

approximately 120 lbs., or 54 kg (for more information, refer to

Appendix A

■ A fully loaded CoreBuilder 5000 Integrated System 10-slot hub weighs

approximately 79 lbs., or 36.8 kg (for more information, refer to

Appendix A

■ A fully loaded CoreBuilder 5000 Integrated System 7-slot hub weighs

approximately 56 lbs., or 25.4 kg (for more information, refer to

Appendix A

■ The surface on which the CoreBuilder 5000 hub is installed is level.

■ For rack installations, the selected rack must be grounded (preferably to a

protective earth ground). Observe the following precautions and guidelines (particularly if your rack has an open back or open sides):

■ Before attempting to rack-mount the hub, first make sure the selected

rack can support at least three times the weight of the hub.

■ To reduce the possibility of personal injury or serious damage to the hub,

install the hub with the help of a partner. This is especially important for rack installations because you must hold the hub in place while securing the hub to the rack.

■ Bolt the rack to the floor.

■ Brace the top of the rack to the wall.

■ Provide sufficient vertical space in your rack for each hub you want to

install.

■ For proper ventilation, install the hub in a rack that has an open back.

■ Install patch panels in the rack for easier cable management.

■ Install the cable tray beneath the hub. The cable tray is designed to

manage the cables exiting from the front of the hub by feeding them under and through the back of the unit.

CoreBuilder 5000 17-slot and 10-slot hubs contain three fan units that draw air in through the front and center of the chassis and exhaust air out the back. The CoreBuilder 5000 7-slot hub contains two fan units that draw air in through the side ventilation panels of the chassis.

To ensure that installed fans are able to provide adequate ventilation, you must allow a minimum of 3 inches (8 cm) between the rear of the hub and the nearest wall (or other vertical surface). The vent holes at the back of the17-slot and 10-slot hubs and on the side of the 7-slot hub are exhaust vents which serve to cool the power supply bay. Do not block these vents.

To ensure that the right side of the 7-slot enclosure provides adequate ventilation, you must allow a minimum of 2 inches (6 cm) of space between the right side of the hub and the nearest wall (or other vertical surface).

CAUTION: Do not operate a CoreBuilder 5000 Integrated System Hub with fewer than two fan units running.

If one fan fails on a CoreBuilder 5000 7-slot Hub only, 3Com recommends that you replace the fan within 48 hours of failure notification or contact your service representative.

Power Requirements The following power requirements are for CoreBuilder 5000 hubs:

■ AC Power – Use a dedicated 15 Amperes (Amps) circuit (or an equivalent

method of providing this current) to supply power to installed CoreBuilder 5000 power supplies when operated at a voltage of between 90 Volts and 130 Volts AC. This ensures adequate power for a fully loaded hub configuration. This circuit must be grounded to a safety (protective earth) ground, not to a neutral ground that carries current back to the transformer.

3-12 CHAPTER 3: INSTALLING THE HUB

■ DC Power – The DC power source must provide:

■ Voltage range – -40 Volts to -57 Volts

■ Permanent power for 1 DC supply – 11 Amps

■ Inrush current for 1 DC supply – 60 Amps and 16 Amps within 16 ms. To

accept the inrush current, use a 100 Amps source to feed up to four -48 Volt DC power supplies.

For detailed information on hub power requirements and installing power supplies, refer to Chapter 4.

Installing the Hub All models of the CoreBuilder 5000 Integrated System Hub are designed to

facilitate easy access, maintenance, installation, and upgrade by service personnel. When installing the hub, be sure to comply with all of the location requirements and power guidelines discussed earlier in this chapter.

WARNING: To reduce the possibility of personal injury or serious damage to the hub, install the hub with the help of a partner. This is especially important for rack installations because you must hold the hub in place while securing the hub to the rack.

Before installing the CoreBuilder 5000 Integrated System Hub in an equipment rack, observe the following precautions:

■ Because the equipment rack environment can cause increased ambient

temperatures and reduced air flow, review the hub specifications and site requirements contained in Appendix A

3-20 CHAPTER 3: INSTALLING THE HUB

■ To ensure mechanical stability and to avoid circuit overloading and improper

Pre-installation Rack-Mount Guidelines

Before attempting to rack-mount the CoreBuilder 5000 Integrated System Hub:

1 First make sure the selected rack can support at least three times the weight of

a fully loaded hub.

2 Bolt the rack to the floor. 3 Brace the top of the rack to the wall. 4 Provide sufficient vertical space in your rack for each CoreBuilder 5000

Integrated System Hub you want to install.

5 For proper ventilation, install the hub in a rack that has an open back. 6 Install patch panels in the rack for easier cable management. 7 Continue to support the weight of the hub until after you have installed four of

the eight screws (two screws per rack-mount flange). Install all eight screws (four screws per rack-mount flange) to fully secure both rack-mount flanges to the rack.

grounding, follow the rack manufacturer’s instructions for rack installation. If the instructions are unclear, consult a qualified electrician.

8 Install the cable tray beneath the hub. The cable tray is designed to manage the

cables attached to the front of the hub by feeding them under and through the back of the unit. Use of the cable tray is optional. You can mount the cable tray onto the rack in one of four positions. Mount the hub using the same rack-mount position settings as those used to mount the cable tray.

WARNING: You can install the hub in the rack either before or after you install the cable tray, but the cable tray must be installed below the hub. Never allow an installed cable tray to support the weight of the hub. The weight of a hub resting on a rack-mounted cable tray may cause the cable tray to buckle or separate from the rack.

All rack-mount illustrations provided in this chapter show the hub installed in a Tel co rack. Install the screws that secure the hub to the Telco rack in open slots on each rack-mount flange.

Telco rack and Metric rack screw locations are shown in Figure 3-16

. For descriptions of Telco and Metric racks, refer to Location Requirements earlier in this chapter.

Installing the Hub 3-21

To install the hub in a Telco rack:

1 Install each of the eight clip nuts provided onto each side of the front of the

rack (four clip nuts per rack-mount flange). Install each clip nut behind a hole into which you plan to install a trusshead screw. Refer to Figure 3-14

WARNING: With a full complement of modules and load-sharing power supplies, the CoreBuilder 5000 Integrated System 17-slot Hub weighs approximately 120 lbs. (54 kg), a CoreBuilder 5000 Integrated System 10-slot Hub weighs approximately 79 lbs. (35.8 kg), and a CoreBuilder 5000 Integrated System 7-slot Hub weighs approximately 56 lbs. (25.4 kg). Therefore, install your 17-slot, 10-slot, or 7-slot hub before you install modules and power supplies. Continue to support the weight of the hub until after you have installed four of the eight screws (2 screws per rack-mount flange) for the 17-slot and the 10-slot hubs only. The 7-slot hub has three rack positions on each side of the hub.

If you attempt to place the weight of the rack-mounted 17-slot or 10-slot hub on fewer than four fully installed screws, the hub may drop off of the rack. Personal injury or serious damage to the hub may result.

2 Slide the hub into the rack until both rack-mount flanges are flush with the

front of the rack.

Figure 3-14

Figure 3-14 Installing a Clip Nut in the Rack

shows the clip nut installation.

Be sure to thread the screw through this nut to securely attach each clip nut to the rack

Rack-mount flanges are set to ’flush mount’ at the factory. If desired, change the rack-mount flange position by removing the screws that attach each flange to the hub. When re-installing the rack-mount flanges on the hub, make sure both flanges are set to the same position before you re-install the screws. Also, make certain that all removed screws are re-installed correctly.

2 Slide the hub into the rack until the hub is flush with the front of the rack. 3 Match the uppermost closed slot on each rack-mount flange to the uppermost

hole on the rack where you previously installed a clip nut. Do not attempt to install screws in open slots on either rack-mount flange.

4 Secure the hub to the rack with the screws provided (eight 10-32 x 1/2-inch

screws). a Install one screw in the uppermost closed slot on each rack-mount flange.

Install two screws per rack-mount flange before you allow the weight of the hub to rest (unaided) on the rack. Tighten all screws completely. A fully

installed screw is flush with the surface of each rack-mount flange.

When installing the hub in a metric rack, install the screws in the closed slots.

b Install the remaining screws in closed slots on each rack-mount flange (for a

total of four screws per rack-mount flange). Install each screw so it is (approximately) equidistant from the screw installed directly above it and the screw installed directly below it. Tighten all screws completely.

WARNING: If you attempt to place the weight of the hub on fewer than four fully installed screws, the hub may drop off of the rack. Personal injury or serious damage to the hub may result.

The CoreBuilder 5000 Integrated System Hub provides a fault-tolerant, intelligent power supply subsystem. The CoreBuilder 5000 Intelligent Power Subsystem supports:

■ Load-sharing AC and DC power supplies

■ High power availability

■ Controller-based power verification features designed to ensure optimal

performance

Table 4-1

Table 4-1 Intelligent Power Subsystem Features

Feature Description

Load-sharing power supplies

describes Intelligent Power Subsystem features.

Provides evenly distributed power consumption among all installed power supplies. Hub activity is not disrupted if a power supply fails because there is no changeover (and hence, no changeover interval).

4-2 CHAPTER 4: INSTALLING POWER SUPPLIES

Table 4-1 Intelligent Power Subsystem Features (continued)

Feature Description

Front-load accessibility Provides easy access for upgrades. As your power needs

Dedicated power supply bay cooling

High power capacity Determines the current power limit. The power mode and the

increase over time, it is easy to upgrade by adding a power supply into the front of the 10-slot and 17-slot hubs (add power supplies from the rear of the the 7-slot hub). Because power supply connectors are keyed to the power distribution board, replacing a faulty power supply is a short procedure.

Cools the power supply bay. Vent holes on the back of the CoreBuilder 5000 Integrated System 10-slot and 17-slot Hubs (vent holes are on the right side of the CoreBuilder 5000 Integrated System 7-slot Hub) reduce the possibility that an overheat condition in the power supply bay will cause or contribute to hub or module failure. This feature works with other hub features to maintain normal hub internal operating temperature.

amount of power available determine the current power limit. The actual power delivered depends on whether you are running in non-fault-tolerant mode or in fault-tolerant mode.

Non-Fault Tolerant Mode:

Depending on the power supply models installed in a 10-slot hub, three power supplies deliver from 885 to 1245 Watts of power to installed modules.

Depending on the power supply models installed in a 17-slot hub, four power supplies deliver from 1180 to 1660 Watts of power to installed modules.

Depending on the power supply models installed in a 7-slot hub, two 295 Watt power supplies deliver from 590 to 705 Watts of power to installed modules and two 415 Watt power supplies deliver 830 Watts of power to installed modules.

(For detailed information on power supply capacity, refer to the sections titled Power Supply Output in Non-Fault-Tolerant Mode and Power Supply Output in Fault-Tolerant Mode in this chapter.)

Fault-Tolerant Mode:

Depending on the power supply models installed in a 10-slot hub, three power supplies deliver from 590 to 830 Watts of power to installed modules.

Depending on the power supply models installed in a 17-slot hub, four power supplies deliver from 885 to 1245 Watts of power to installed modules.

Depending on the power supply models installed in a 7-slot hub, two 295 Watt power supplies deliver from 295 to 415 Watts of power to installed modules and two 415 Watt power supplies deliver 415 Watts of power to installed modules.

If a power supply fails while the hub is running in fault-tolerant mode, still-functioning supplies provide all of the power necessary to keep installed modules and the hub running. (One power supply capacity is held in reserve.) This is because the power reserved for fault-tolerance is made available to modules already powered on. Hence, the failure of a power supply has no impact to the system.

CoreBuilder 5000 Power Supply Models 4-3

Table 4-1 Intelligent Power Subsystem Features (continued)

Feature Description

Controller Module-based software-driven power management

Confirms that there is enough power for the CoreBuilder 5000 module. The CoreBuilder 5000 Fault-Tolerant Controller Module (Model Number 6000M-RCTL or 6000M-CMGT) polls each new CoreBuilder 5000 module installed in the hub to confirm enough power is available for the CoreBuilder 5000 module. If available power is:

Adequate – The new CoreBuilder 5000 module powers on. Inadequate – The new CoreBuilder 5000 module does not

power on. System overload is avoided. Software-driven power management (Intelligent Power

Management) also provides protection against the possibility of a catastrophic power failure. If the hub is operating in power non-fault-tolerant mode and a power supply fails, installed Controller Modules power off selected (low power class) CoreBuilder 5000 modules until the power deficit is corrected. Intelligent Power Management ensures that key components and resources continue to operate, even under extreme failure conditions.

(If the hub is configured with a DMM module, alerts and traps are sent to the network management applications regarding any changes.)

CoreBuilder 5000 Power Supply Models

Table 4-2 lists the power supplies supported by the CoreBuilder 5000 Integrated

System Hub.

Table 4-2 CoreBuilder 5000 Integrated System Hub Power Supply Models

Model Number Watts Input Power Type

6000PS 295 AC 6000PS-48V 295 DC 6000PS-HO 415 AC

You can purchase the power supply model numbers that your configuration requires. You can use any combination of power supplies in your hub, ranging from all of one type to a mixture of all three types.

Some products may contain the prefix ’3C9’. These are the same as those that do not contain this prefix.

Full support of the 6000PS-48V and 6000PS-HO power supplies requires that you load DMM software Version v2.3 or later and Controller software Version v1.1 or later. Earlier software versions support these models as unknown 295 Watt power supply types.

4-4 CHAPTER 4: INSTALLING POWER SUPPLIES

Determining the Model Number of Your Power Supply

After hub installation (refer to Chapter 3), if your hub is managed by a CoreBuilder 5000 Distributed Management Module, determine the model number of your power supply to configure your environment appropriately. Each power supply has its own requirements. To determine the Model Numbers of your power supplies:

1 Enter the SHOW HUB command. 2 Press Enter.

Chapter 6 provides information about the SHOW HUB command.

For information on how power supplies ship, refer to Chapter 3, the section titled Second Shipping Box Contents.

Power Requirements This section describes the following power requirements for the

CoreBuilder 5000 Integrated System Hub:

■ AC Power

■ -48 Volt DC Power

Use a dedicated 15 Amperes (Amps) circuit (or an equivalent method of providing this current) to supply power to installed CoreBuilder 5000 power supplies when operated at a voltage of between 90 Volts and 130 Volts AC. This ensures adequate power for a fully loaded hub configuration. This circuit must be grounded to a safety (protective earth) ground, not to a neutral ground that carries current back to the transformer.

WARNING: Do not use electrical conduit pipe as your only means of grounding the hub.

When you use a single circuit to power multiple load-sharing power supplies, that single circuit may be required to deliver more than 15 Amps. This depends on the number of installed power supplies and on the voltage configuration. Load-sharing power supplies always draw power when inserted into the hub. There is no low-power standby mode of operation.

WARNING: For use in Denmark, each 6000PS-HO power supply must receive power from a separately dedicated socket outlet having a 16 Amp fuse in the installation.

WARNING: Ved brug i Danmark, skal hver 6000PS-HO stromforsyning modtage strom fra en separat, dedikeret stikkontakt med en 16 Amp sikring i installationen.

AC Power Requirements CoreBuilder 5000 load-sharing AC power supplies are autosensing. Each power

supply can automatically sense (identify) the type of input AC voltage to which it is being connected at the wall outlet. Compatible voltages are as follows:

■ Europe – 220 Volts to 240 Volts

■ North America – 110 Volts to 220 Volts

■ Japan – 100 Volts

DC Power Requirements The -48 Volt DC power supply must provide:

■ Voltage range – -40 Volts to -57 Volts

■ Permanent power for 1 DC supply – 11 Amps

■ Inrush current for 1 DC supply – 60 Amps and 16 Amps within 16 ms. To

accept the inrush current, use a 100 Amps source to feed up to four -48 Volt DC power supplies.

CAUTION: Use only the power cord supplied in the -48 Volt DC power supply shipping box. Only qualified service personnel should install the power cord to the DC power source.

For instructions on how to install the -48 Volt DC input power cord, refer to the section titled Installing the -48 Volt DC Power Supply and Power Cord later in this chapter.

Load-Sharing Power Supplies 4-5

Load-Sharing Power Supplies

This section describes available power modes and power supply capacity in each power mode.

Table 4-3

lists the number of power supplies each CoreBuilder 5000 Integrated

System Hub can accommodate.

Can accomodate this number of power

supplies....

CoreBuilder 5000 Integrated System Hubs can ship with or without power supplies. For information on how hubs are shipped, refer to Chapter 3, the section titled Removing the Hub and Components From the Shipping Boxes.

Power Supply Modes The CoreBuilder 5000 Integrated System Hub runs in either of two power supply

output modes:

■ Power Non-Fault-Tolerant Mode

■ Power Fault-Tolerant Mode

The following sections describe:

■ Power Supply Modes

■ Power Availability and Power Supply Capacity

For optimal power redundancy in either power mode, run the hub with at least one power supply more than the minimum number required to operate all installed modules and all modules you plan to install.

4-6 CHAPTER 4: INSTALLING POWER SUPPLIES

Power Non-Fault-Tolerant Mode

Power non-fault-tolerant mode is:

■ A user-selectable mode in which 100 percent of the power that can be

allocated to modules is available to them (no power is held in reserve).

■ The default mode for power supplies as shipped.

While the hub is running in power non-fault-tolerant mode, the amount of power available to modules is determined by the number and type of installed power supplies. For example, if your hub is in non-fault-tolerant mode and has a mixture of 415 Watt (6000PS-HO) and 295 Watt (6000PS and 6000PS-48V) power supplies, the 415 Watt power supplies deliver 415 Watt and the 295 Watt power supplies deliver 295 Watts.

If a power supply fails while the hub is running in power non-fault-tolerant mode:

■ Installed Controller modules may shut down selected CoreBuilder 5000

modules in an attempt to bring installed module power consumption under the now-reduced power budget.

■ Installed modules continue to operate without interruption if the output of

at least one installed power supply is not required by installed modules when a power supply fails.

For more information, refer to Chapter 2, the section titled CoreBuilder 5000 Module Power-Down Response.

CAUTION: When switching on power supplies in a hub containing ONline modules, switch all installed power supplies on simultaneously to avoid the possible shutdown of one or more power supplies. This is necessary only when the power required by installed ONline modules is greater than the capacity of the first power supply you switch on. For example, if you switch on one power supply at a time, the first power supply you switch on may get overloaded and shut down before a second power supply can power up and share the load. Also, if a power supply shuts down due to an overload, be aware that you must wait at least 10 seconds before attempting to switch that power supply on again.

Power Fault-Tolerant Mode

Power fault-tolerant mode is a user-selectable mode in which one power supply’s worth of power is held in reserve. This reserve power is not available to installed modules until a power supply fails, or until the user switches the power mode from power fault-tolerant mode to power non-fault-tolerant mode.

While the hub is running in power fault-tolerant mode:

■ All installed power supplies are functioning and contributing power to the

hub. No single power supply is a dedicated standby power supply. Rather, a factory-defined power limit (based on the number of installed power supplies) ensures that at least one power supply’s worth of power is available to replace power lost when a power supply fails.

Load-Sharing Power Supplies 4-7

■ The amount of power required by installed modules must not be greater

than the number of installed power supplies minus one (N-1). When you reserve one power supply’s worth of power in power fault-tolerant mode, the failure of a single power supply has no impact on installed modules already powered up.

If your hub has a mixture of 415 Watt (6000PS-HO) and 295 Watt (6000PS and/or 6000PS-48V) power supplies (only in fault-tolerant mode), the 415 Watt power supplies are treated as if they were 295 Watt supplies. In most cases, it is not to your advantage to mix 415 Watt and 295 Watt power supplies when running in fault-tolerant mode.

If a power supply fails while the hub is running in power fault-tolerant mode:

■ Active and Standby Controller Modules respond by automatically disabling

power fault-tolerant mode.

■ Power formerly reserved (unavailable to installed modules) is made available

to power enabled CoreBuilder 5000 modules to prevent them from powering down by power class and slot location (as an attempt to bring power consumption under the now-reduced power budget).

Power Availability and

Power Supply Capacity

■ All modules that had power before the power supply failure continue to

receive power without interruption.

■ Upon power supply recovery, power fault-tolerant mode is automatically

re-enabled.

To prevent Active and Standby Controller Modules from automatically disabling power fault-tolerant mode in response to a power supply failure, ensure that the number of installed power supplies is equal to or greater than N-2 (two extra power supplies). In a hub with at least two extra installed power supplies, N-1 power supplies continue to be available to run the hub in power fault-tolerant mode, even after a single power supply fails. If a power supply failure occurs under any condition, an alarm is sent to the Network Management applications.

This section explains the following concepts concerning power supply management:

■ Power available to modules – The amount of power available to modules

is determined by the number and type of installed power supplies.

■ Power capacity of a power supply – The power capacity of a power

supply unit is the amount of power the power supply delivers. For example, the 415 Watt power supply delivers 415 Watts and the 295 Watt supply delivers 295 Watts.

When managing power in your system, consider the system overhead, that is, the power consumed by the hub itself (fans, TriChannel signalling, Controller Module). Before installing any new module into a hub, you should assess the power budget by calculating the total power requirements for all installed modules, fans, and controllers.

4-8 CHAPTER 4: INSTALLING POWER SUPPLIES

Refer to the documentation supplied with each module to determine your module power requirements. Take into account any modules you plan to install, as well as those already installed.

System overhead amount consumes 18 Watts of the +12 Voltage and 1 Watt of the +5 Voltage.

Managing Power in the Hub

The Controller Module provides comprehensive power management for the CoreBuilder 5000 Integrated System Hub and all installed CoreBuilder 5000 modules.

ONline modules cannot be power managed, but an installed Master DMM (Distributed Management Module) maintains an ONline module power consumption table. This table lists power consumption values for specific ONline module types (for example, a BNC Module). The Master DMM provides these ONline power consumption values to installed Controller Modules so the Controller Modules can maintain an accurate power budget.

For more information, refer to Appendix B, ONline Module Power Consumption and Voltages and Watts Consumed Per Module.

For more information about the DMM commands discussed below, refer to the

CoreBuilder 5000 Distributed Management Module Commands Guide.

This section describes:

■ Establishing Power Fault-Tolerance

■ Power Supply Output in Non-Fault-Tolerant Mode

■ Power Supply Output in Fault-Tolerant Mode

■ Enabling and Disabling Power to Slots

Establishing Power

Fault-Tolerance

■ CoreBuilder 5000 Module Power Class Settings

Operate the hub in power fault-tolerant mode to ensure that at least one supply’s worth of power is available to replace power lost when and if a single power supply fails.

To set the hub to power fault-tolerant mode or power non-fault-tolerant mode, enter the SET POWER MODE command at the DMM prompt.

When you attempt to set the hub to power fault-tolerant mode, Active and Standby Controller Modules determine if there is sufficient unallocated power budget available to place one power supply’s worth of power in reserve.

■ If there is sufficient unallocated power budget, the hub sets to power

fault-tolerant mode.

■ If there is insufficient unallocated power budget, the hub remains in power

non-fault-tolerant mode.

Managing Power in the Hub 4-9

Determining Hub Power Budget

To ensure optimal power fault-tolerance, determine the current power budget for the hub as follows:

1 If you have installed a CoreBuilder 5000 Distributed Management Module in

your hub, enter the SHOW POWER BUDGET command at the terminal prompt. The SHOW POWER BUDGET command shows the amount of power currently

available for modules:

■ Total power installed

■ Amount of power consumed

■ Amount of power available

Compare this information with the power requirements for each module installed in the hub. Refer to the documentation supplied with each module to determine your module power requirements. Take into account any modules you plan to install, as well as those already installed.

Power supply output values displayed by the SHOW POWER BUDGET command have been rounded down. Therefore, these values may not precisely match those provided in the documentation shipped with each power supply.

Power Supply Output

in Non-Fault-Tolerant

Mode

2 Examine the output of the SHOW POWER BUDGET command. If necessary, add

another power supply to your hub.

If your software version of the DMM is earlier than software Version v2.3, any 6000PS-HO or 6000PS-48V power supplies you are using are interpreted as unknown 295 Watt power supply types.

In the power supply output tables below, values are rounded values that do not include system overhead (fans, TriChannel signalling, and two installed Controller Modules).

Table 4-4

shows the power available in power non-fault-tolerant mode (by voltage type) when the power supplies are 295 Watts, AC (Model Number 6000PS) or DC (Model Number 6000PS-48V). Power output for the

-48 Volt DC power supply is identical to the 295 Watt AC power supply.

Enabling and Disabling

Power to Slots

In summary, you can establish power fault-tolerant mode only if:

■ Power budget consumed is less than or equal to the power delivery

capability provided by N-1 power supplies.

■ The hub is managed by an installed CoreBuilder 5000 Distributed

Management Module.

If you have an installed Distributed Management Module (DMM), you can use CoreBuilder 5000 power management commands to enable or disable power to any selected slot containing a CoreBuilder 5000 module. Installed Controller Modules allow you to enable power to a slot, but only if there is sufficient unallocated power budget to power up the module installed in the slot.

Managing Power in the Hub 4-13

This section describes:

■ Power Enabled State

■ Power Disabled State

Power Enabled State

To enable power to a specified slot:

1 Enter the SET POWER SLOT MODE ENABLE command. 2 Press Enter.

If there is:

■ Sufficient power available to meet the requirements of the

CoreBuilder 5000 module, installed Controller Modules enable power to the specified slot and reduce the power budget by the amount of power the CoreBuilder 5000 module installed in that slot consumes.

■ Insufficient power to meet the requirements of the CoreBuilder 5000

module, the CoreBuilder 5000 module remains in power pending state until sufficient power becomes available.

A CoreBuilder 5000 module that was powered down due to a lack of sufficient available power is in power pending state. The module can be automatically powered up again by installed Controller Modules when sufficient power becomes available.

Power Disabled State

A CoreBuilder 5000 module in power disabled state is a CoreBuilder 5000 module that was powered down. A CoreBuilder 5000 module in power disabled state is not eligible to be automatically powered up again when sufficient power becomes available.

To disable power to a CoreBuilder 5000 module in a specified slot:

1 Enter the SET POWER SLOT MODE DISABLE command. 2 Press Enter.

Upon disabling power to a slot containing a CoreBuilder 5000 module, the power previously consumed by the CoreBuilder 5000 module is returned to the unallocated power budget (that is, to the power available budget).

ONline Management Modules do not provide a user interface to Controller Module power management functionality.

4-14 CHAPTER 4: INSTALLING POWER SUPPLIES

CoreBuilder 5000

Module Power Class

Settings

A power class setting is a user-definable value ranging from 1 through 10 (10 is the highest possible power class setting). You can define the power class setting for any installed CoreBuilder 5000 module to make one CoreBuilder 5000 module more important or less important than another.

Installed Controller Modules use default and user-defined power class settings to make power management decisions. For example, installed Controller Modules use CoreBuilder 5000 module power class settings to determine the order in which installed CoreBuilder 5000 modules power up and power down under certain power deficit and overheat conditions.

This section describes:

■ Using the Default Power Class Setting

■ Setting Power Class Manually

■ Power Class 10 Warnings

Using the Default Power Class Setting

Each CoreBuilder 5000 module is shipped with a default power class setting of 3.

■ Assign higher power class settings to all installed DMMs, and assign the

highest power class setting of any installed CoreBuilder 5000 module to the Master DMM. This assures that the Master DMM powers down last (after all other installed CoreBuilder 5000 modules).

■ Assign a higher power class setting to any CoreBuilder 5000 module

connected to critical network resources.

Setting Power Class Manually

To set the power class for a CoreBuilder 5000 module in a specified slot:

1 Enter the SET POWER SLOT CLASS command. 2 Press Enter.

Refer to the CoreBuilder 5000 Distributed Management Module Commands Guide for a discussion of this feature.

Even though it has a power class setting, a Controller Module cannot be power managed. A Controller Module always draws power when inserted in the hub, and a Controller Module cannot be powered down using a DMM command.

Power Class 10 Warnings

A CoreBuilder 5000 module assigned a power class setting of 10 cannot be automatically powered down by installed Controller modules.

For example, if a power supply failure causes a power deficit (or if a hub overheat condition develops while OVERHEAT_AUTO_POWER_DOWN is enabled), a CoreBuilder 5000 module assigned a power class setting of 10 continues to run until you order it to shut down. Under some conditions (such as an extended overheat condition), hub or module hardware damage may result.

Installing Power Supplies 4-15

To ensure that installed Controller Modules are able to automatically make all power management decisions without waiting for user intervention, do not assign a power class setting of 10 to any CoreBuilder 5000 module unless absolutely necessary.

Installing Power Supplies

Installing a

Load-Sharing AC Power

Supply

This section contains the following topics:

■ Installing a Load-Sharing AC Power Supply

■ Installing a -48 Volt DC Power Supply and Power Cord

■ Removing a -48 Volt DC Input Power Supply and Power Cord

Due to regulatory safety issues, a -48V DC power supply can only exist in a rack or an enclosed cabinet. As a result of this placement restriction, a CoreBuilder 5000 hub containing both an AC power supply and a -48V DC power supply must be installed in an enclosed cabinet or in a rack. Table or shelf-mounted CoreBuilder 5000 hubs cannot contain -48V DC power supplies.

To ensure optimal power redundancy, determine current hub power requirements. For more power requirement information, refer to the section titled Allocating Sufficient Power for Installed Modules, later in this chapter.

You can install power supplies in any of the power supply slots. A factory label located directly below the power supply slots identifies the slot number associated with each power supply.

For important recommendations on power monitoring, reporting, and maintenance, refer the section titled Managing Power in the Hub earlier in this chapter.

For the 7-slot hub, power supplies are installed using the same procedures except you install the power supply horizontally instead of vertically. A label is affixed to the power supply to identify the ON ( ) position of the power supply switch.

4-16 CHAPTER 4: INSTALLING POWER SUPPLIES

Figure 4-1 shows the location of the label for the ON ( ) position for the 7-slot

hub power supply.

ON/OFF label for the power supply in a 7-slot hub is located in this area

Figure 4-1 Location of the ON Position Label for 7-slot Hubs

To add a power supply to the CoreBuilder 5000 Integrated System Hub:

1 Remove the blank faceplate covering each slot in which you will install a power

supply. Keep this blank faceplate for later use.

2 Set the ON/OFF (  / Ο ) switch on the front of the power supply you are

installing to the OFF ( Ο ) position before inserting the power supply into the hub.

3 Slide the power supply into the selected power supply slot. Push the power

supply unit into the hub until the front panel of the power supply is flush with the front of the hub. The rear power supply connectors should now be firmly seated into the hub power supply connectors.

Screws on the power supply

Slide the power supply into the selected slot as shown here

Figure 4-4 Installing a Load-Sharing Power Supply in a 7-slot Hub

4 Fasten the power supply to the hub by tightening the two screws on the power

supply faceplate. Ensure that both screws are securely fastened (tighten the screws to Torque Specification 3 to 5 inch pounds).

5 Plug the power cord into the power supply socket. 6 Plug the power cord into the wall outlet. 7 Set the power supply’s ON/OFF switch (  / Ο ) to the ON (  ) position.

Optionally, wait until all modules are installed before setting the switch to the ON (  ) position.

CAUTION: When switching on power supplies in a hub containing ONline modules, switch on all installed power supplies simultaneously to avoid the possible shutdown of one or more power supplies. This is necessary only when the power required by installed ONline modules is greater than the capacity of the first power supply you switch on. For example, if you switch on one power supply at a time, the first power supply you switch on may overload and shut down before a second power supply can power up and share the load. Also, if a power supply shuts down due to an overload, be aware that you must wait at least 10 seconds before attempting to switch on that power supply again.

The power supply should now be fully operational.

CAUTION: When one or more power supplies are active, module and power supply slots carry electric current. To avoid possible electric shock and damage to hub components, do not place hands, tools, or other objects (other than properly installed modules and power supplies) into exposed module or power supply slots. Do not allow liquids of any kind to contact exposed slots.

Installing Power Supplies 4-19

Installing a -48 Volt DC

Power Supply and

Power Cord

This section describes how to prepare and install a -48 Volt DC power supply and power cord in your hub. The -48 Volt DC power supply is a DC version of the AC 295 Watt power supply and provides the identical power output of the 6000PS power supply.

The DC input cable ships with the 6000PS-48V power supply.

WARNING: Only trained electrical service personnel should make connections and disconnections to the -48 Volt DC power source. A circuit breaker (short-circuit protection) must be set up in the main power source. This circuit must be grounded to a safety ground (protected earth). For each power supply use one 20 Amp protection device to protect the cabling of the -48 Volt DC power supply against short circuits.

WARNING: To comply with UL requirements, the -48 Volt DC power supply must only be installed in a rack-mounted CoreBuilder 5000 hub or a CoreBuilder 5000 hub installed in an enclosed cabinet.

CAUTION: The -48 Volt power supply switch only shuts off the output side of the power supply.

Before You Begin

You must read the notices in this section before you install the -48 Volt DC power supply and power cord.

CAUTION: Connect the -48 Volt DC power supply to Safety Extra Low Voltage supply (SELV) only. Carefully read the safety label attached to the power supply unit you received.

WARNING: Make certain that the building power source is turned OFF (circuit breaker is in the OFF position).

Before you install the -48 Volt DC power supply:

1 Verify that the power source is compatible with the voltage and tolerances

specified on the input rating plate located on the power supply unit. The nominal value is -48 Volt DC, 11 Amps.

2 Remove the following items from the shipping box:

a Power supply b Power input cable c Terminal rings

The -48 Volt DC power supply ships with different size terminal rings. One terminal ring is for only the green/yellow ground wire. The remaining terminal rings are used with the red and black wires. Choose the correct terminal rings to support your installation.

The AMP part number for the terminal crimping tool is AMP Number 58433-2 (this includes the correct crimping die set). The AMP Die Set part number is 58423-1 (if you already have the crimping tool with other dies).

The following terminal ring installation shows how you install terminal rings to the power cord. The installer should adapt the building DC input and make the power cord connection using the terminal rings shipped with the power supply or whatever method is necessary to meet system installation requirements. For compatibility with the building power source, the installer chooses which size terminal rings should be crimped on the power cord wires.

Preparing and Installing the DC Input Power Cord

To prepare and install the -48 Volt DC input power cord:

1 Obtain the power supply cable that you removed from the shipping box. The

input power cable has three groups of wires. Each wire is labeled with the corresponding voltage. The two red wires are labeled 48VDC and the two black wires are labeled 0VDC.

Installing Power Supplies 4-21

Figure 4-6 shows the 6000PS-48V Power Supply input power cord.

2 red wires (-48 Volt DC)

1 green/yellow ground wire

2 black wires (0 Volt return)

Figure 4-6 -48 Volt DC Input Power Cord

To comply with UL requirements, the power cord must be routed through a rack or cabinet raceway to the rack or cabinet distribution panel delivering the -48 Volt DC input power. The cable may be routed to the back using the cable tray option of the CoreBuilder 5000 hub.

Safety label

Keyed connector

CAUTION: You must install the green/yellow ground wire first.

2 Fit the appropriate terminal rings to each wire of the power cord and tighten

them with a crimping tool according to the AMP rings size. Each wire has a terminal ring at the end (see Figure 4-7

Terminal ring

Figure 4-7 Terminal Ring on Each Wire

3 Connect the cable ground wire (green/yellow) to the ground terminal lugs.

The power source should be labeled with minus (-) and positive (+) symbols.

4 Take the two black wires and connect the two black wires to the positive (+)

symbol on the power source (zero Volt return).

4-22 CHAPTER 4: INSTALLING POWER SUPPLIES

5 Take the two red wires and connect the two red wires to the minus (-) symbol

of the power source (-48 Volt).

Installing the -48 Volt DC Power Supply

To install the -48 Volt DC power supply:

1 Make certain that the power supply’s ON/STANDBY switch is in the STANDBY

position.

2 After removing a blank faceplate that covers a power supply slot, carefully slide

the power supply into the selected slot of the CoreBuilder 5000 hub chassis.

3 Fasten the power supply to the hub by tightening the two spring-loaded screws

on the power supply faceplate. Ensure that both screws are securely fastened (tighten the screws to Torque Specification 3 to 5 inch pounds).

4 Plug the keyed cable connector into the power supply socket (see Figure 4-8).
