Removing a Module
ATMSpeed/155 modules can be hot-inserted in a chassis at any time. However, to
remove an active module from the Centillion 100 chassis, 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. Using the medium flat-tip screwdriver, loosen the two captive retaining
screws on the module until they pop free of the chassis.
4. Rotate the left and right inserter/extractor levers away from the center of
the module to their protruding positions (see Figur
e 2-31).
The module is disengaged from the backplane.
Note: If the power for the Centillion 100 chassis is off, this step is not
necessary.
Caution: If you remove a module without waiting 45 seconds after
disabling the ports, you must power cycle the Centillion 100 chassis.
When you turn off the power on the Centillion 100 chassis, you must wait
15 to 20 seconds before turning the power back on. The Centillion 100
modules begin switching an additional 15 to 20 seconds after power is
resumed.
