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.
