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