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.
