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:

C4K_CHASSIS-2-INLINEPOWEROFF

C4K_CHASSIS-2-INSUFFICIENTPOWERDETECTED

C4K_CHASSIS-2-INSUFFICIENTPOWERSHUTDOWN
