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:
