Nortel Networks 5000BH manual Replacing a TokenSpeed Module, Loosening the TokenSpeed module

Using the 8-port TokenSpeed and TokenSpeed/MCP Switch Modules

Replacing a TokenSpeed Module

You do not need to turn off the switch power before you replace a TokenSpeed module that does not have an MCP.

To replace a TokenSpeed module, follow these steps:

1.Disable all ports on the module using SpeedView, or disconnect the cables from each port.

Disabling the ports on a module is described in Using SpeedView 2.1 for Windows.

2.Wait 45 seconds.

Waiting allows the system software to process the requests to disable the ports.

Caution: If you remove a module without waiting 45 seconds after disabling the ports, you must power cycle the Centillion switch chassis. When you turn off the power on the Centillion switch chassis, you must wait 15 to 20 seconds before turning the power back on. The TokenSpeed modules begin switching an additional 15 to 20 seconds after power is resumed.

3.Loosen the two retaining screws on the module until they pop free of the chassis frame (see Figure 3-11).
