Nortel Networks 5000BH manual Removing and Replacing a Module

Installing and Connecting the TokenSpeed Module

Predefined configurations are available for the following applications:

•All transparent switching with no spanning tree support

•All transparent bridging with IEEE 802.1d spanning tree support

•All source route bridging between token rings (see Table 3-3 for default ring numbers) with IBM spanning tree support

You must enter additional configuration information if you are using any of the following features:

•Virtual rings

•Filtering

•Source routing ring numbers that are different than the default values

•Combinations of bridging modes and spanning tree not offered as defaults

For instructions for using these features, refer to Using SpeedView 2.1 for

Windows.

Removing and Replacing a Module

A TokenSpeed module can be hot inserted in a chassis at any time, but a TokenSpeed/MCP module should not be removed from a functioning switch. Installing a TokenSpeed/MCP module resets the switch and loads the default configuration, thus interrupting network connectivity.

If you are adding a module to an empty slot in an already functioning switch, follow the instructions that begin on page 3-2. If you are replacing an installed module, follow the instructions in the next two sections.

To remove or replace a TokenSpeed or TokenSpeed/MCP module, you need a medium-size flat-tip screwdriver to loosen and tighten the retaining screws on the module.

If you suspect that a TokenSpeed module is malfunctioning, see Chapter 4, “Troubleshooting the TokenSpeed Module,” before you replace the module.

Note: To minimize configuration conflicts, you should replace a module with another identical module. If the new module is not identical to the module previously in that slot, the new module remains inoperative until it is reconfigured using SpeedView.
