Frame Power Supply Failure

The number of power supplies in the frame depends on the size of frame you have, and if the redundant power option is installed.

When a frame power supply fails, the switcher identifies the failed component on the Status menu. Use this information to trouble-shoot the power supply and replace it if required.

There are a number of LEDs on the power supply that can identify what is wrong with the power supply.
