Installing and Connecting the TokenSpeed Module
893-01019-A 3-11
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 T
able 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.
