Checking LEDs

PWR01

PWR02

LEDs on PSUs, fans, and the front panels of switches indicate the operational status of the devices. After you have installed a PSU or fan and have powered on the switch, check the LEDs to verify operation by using the following tables.

The following table describes LEDs on the PWR01 and PWR02 power supply units.
