Error LED

Critical faults on the service controller are indicated through the amber error LED.

The error LED has the following two states:
OFF
The service controller is functioning correctly.
ON
A critical service-controller failure was detected and you must replace the service controller.

The error LED can light temporarily when the node is powered on. If the error LED is on, but the front panel display is completely blank, wait five minutes to allow the LED time to turn off before performing any service action.
