Determining which power supply failed

If you are replacing a power supply that has failed and you are not sure which supply has failed,
enter the following command at any CLI command prompt:

This command displays status information for the power supplies and the fans. The power supplies
are numbered from left to right. These numbers assume you are facing the front of the device, not
the rear.

If the display indicates “Installed (Failed)” for any of the slots, the power supply installed in that
particular slot has failed.
