Fan Module LEDsThe fan module LED is located below the air holes on the front of the module.

StatusColorLED

The fan module is operational.GreenSTS

The fan module is not operational (fan is probably not functional).Red

Fan module is not receiving power.Off

Power Supply LEDsThe power supply LEDs are located on the left front portion of the power supply. Combinations of states

indicated by the Okay ( ) and Fault ( ) LEDs indicate the status for the module as shown in the followingtable.
