Troubleshooting the Power Supply
If you are unable to resolve the problem, or if you determine that either a power
supply or backplane connector is faulty, contact the Cisco Technical Assistance
Center (TAC) for instructions.
Troubleshooting Power Problems using Cisco IOS
Check for system messages related to the power supply, and refer to the system
message guide for your software release. You may need to add a power supply or
upgrade to a larger one for your current configuration or verify that the switches
are set properly. Connect a terminal to the console port, and look for any of the
following system messages:
