Disabling the Fast

Reset Function

Installing the Module in a CoreBuilder 5000 Hub

The Fast Reset function restores clock synchronization to the engines if a controller switchover occurs in the CoreBuilder 5000 hub.

■ If the engine supports Fast Reset, do not change the jumpers from

their default settings.

■ If the engine does not support Fast Reset, disable it. Disabling Fast

Reset causes a normal engine reset to occur during a controller switchover.

To disable Fast Reset, insert the appropriate jumper (see Table 2-3

)

on the CoreBuilder 5000 Carrier.

You do not need to power down the CoreBuilder 5000 hub to install or remove the module. You can insert the module while the hub is operating (this is called a hot swap).

To install the module:

1 Use one of the following proper grounding techniques when you install

the module:

■ Properly ground yourself prior to handling the module.

■ Attach a static wrist guard to yourself or touch a grounded static

mat prior to handling the module.

2 To determine if the hub has enough power for the new module, enter

the SHOW POWER BUDGET command. Refer to Appendix A

for details on power requirements for each of the specified wattages. For engine power requirements, refer to the documentation for the engine.

Refer to the CoreBuilder 5000 Distributed Management Module Commands Guide for information on the SHOW POWER BUDGET command.

3 Locate an open slot in the hub. If necessary, remove a blank panel to

expose a slot.

In this chapter, the section Configuring the Carrier on page 3-5 describes how to use management commands to make basic changes to carrier configuration settings. For complete instructions on using management commands to manage the carrier, refer to one of the following:

■ CoreBuilder 5000 Distributed Management Module User Guide

(Document Number 17-00370)

■ CoreBuilder 5000 Management Module Commands Guide

(Document Number 17-00372)

The 3Com CoreBuilder 5000 Manager is an SNMP manager with a graphical user interface. For instructions on using the CoreBuilder 5000 Manager to manage the carrier, refer to the CoreBuilder 5000 Manager for UNIX User Guide (Document Number 17-00320).

This section describes the possible sources of carrier configuration settings and the factors that determine which configuration source the carrier uses. This section contains the following sections:

■ Carrier Configuration Sources

■ Hot-Swap Installation

Carrier

Configuration

Sources

■ Determining the Carrier Configuration Source

In a managed hub (hub with a DMM installed), the carrier obtains its configuration settings from one of the following sources:

■ DMM settings

■ Carrier NVRAM settings

■ Carrier DIP switch settings

■ Carrier default settings

DMM Settings

The DMM can provide configuration settings to the carrier if you are performing a hot-swap. For more information on hot-swapping, refer to Hot-Swap Installation on page 3-4.

Carrier Configuration Source Overview 3-3

Carrier NVRAM Settings

The carrier can store configuration settings in its NVRAM (Non-Volatile Random Access Memory), which it can use when powering up in either a managed or unmanaged hub. Two NVRAM DIP switches control whether or not the carrier uses NVRAM settings. When the carrier is shipped from the factory, its NVRAM contains no settings.

The carrier stores settings in NVRAM when either of the following occurs:

■ You use a DMM configuration command or an SNMP manager to

change a carrier configuration setting. For example, if you use the SET PORT NETWORK command to change a carrier port network assignment, the carrier stores the new network assignment in its NVRAM.

The carrier stores the new setting as soon as you issue the command. The SAVE command does not affect the contents of NVRAM.

■ The DMM sends settings to the carrier during a hot-swap. For a

definition of hot-swap, refer to Hot-Swap Installation on page 3-4.

For information on setting the NVRAM DIP switches, refer to Enabling or Disabling NVRAM Configuration Settings on page 2-11.

Carrier DIP Switch Settings

The carrier contains a DIP switch that you can use to configure port network assignments. For more information on DIP switch settings, refer to Setting the Carrier DIP Switches on page 2-9.

Carrier Default Settings

In some cases the carrier uses default configuration settings contained in its software. The carrier contains the following default settings for port network assignment:

■ Ports 1 and 5 use Isolated_1

■ Ports 2 and 6 use Isolated_2

■ Ports 3 and 7 use Isolated_3

■ Ports 4 and 8 use Isolated_4

3-4 CONFIGURATION

Hot-Swap Installation Whether or not you hot-swap the carrier affects which configuration

source the carrier uses.

Removing a carrier from the hub and installing an identical model carrier in the same slot is a hot-swap. When you perform a hot-swap, the DMM teaches the new carrier the configuration used by the old carrier. The new carrier saves the settings in its NVRAM.

The DMM teaches the new carrier only if it has a saved configuration for the old carrier installed in that slot. The DMM saves the configuration when you do one of the following:

■ Issue the SAVE command.

■ Use SNMP to make the configuration changes to the carrier. The

DMM automatically saves the changes.

■ Reset or power-cycle the DMM. The DMM automatically learns and

saves the NVRAM configurations of all installed modules.

Swapping in a new carrier that contains a different engine from the old carrier is still a hot-swap. Only the carrier models must be the same.

* Use the SHOW DEVICE command to view the DIP configuration setting. Use the SET DEVICE

DIP_CONFIGURATION command to change the DIP configuration setting.

† If there are no settings stored in carrier NVRAM, the carrier uses default settings.

If the DMM detects a problem with the NVRAM configuration, it forces the carrier to use default settings. For example, if you install the carrier with ports assigned to Ethernet_8 into a CoreBuilder 5000 hub model that does not support Ethernet_8, the DMM forces the carrier to use default settings. If the configuration problem is port-level, the DMM forces only the affected ports to use default settings.

‡ The DMM must be fully initialized when you install the carrier module.

Configuring the Carrier

This section describes how to configure the carrier using network management commands. It contains the following sections:

■ Selecting a Network

■ Saving the Configuration

■ Showing Carrier Configuration and Status

Selecting a Network The engine connects to the backplane through backplane ports on the

carrier. The carrier provides a total of eight backplane ports. Engine 1 uses ports 1 to 4 and Engine 2 uses ports 5 to 8. Depending on the engine architecture, the engine may not use all of the ports.

3-6 CONFIGURATION

You can assign a carrier module port to:
