Caution: The router detects error and warning conditions by comparing the
number of power modules detected to the number of power modules in the
configuration information. If a power module is added or removed, the power
supply configuration must be updated to ensure the proper warning and error
conditions will be detected.
Caution: To prevent static shock, which can damage electrical equipment, use
industry accepted handling practices when servicing the router and its
components. See Appendix E, “Electrostatic Discharge,” for more information.
Removing a Power Module or Power Bay Cover
To remove a power module or power bay cover:
1. Loosen the thumbscrews 1 in a counterclockwise rotation on the power
module or the power bay cover as shown in Figure 112 and Figure 113.
The thumbscrews cannot be physically detached from the modules, but can be
loosened so that the power module or power bay cover can be removed, as
described in Step 2.
