Disk drive LEDs

The disk fault LED on the system status and control panel indicates the general status of the disk subsystem. The disk fault LED lights when a fault is detected in the disk subsystem. LEDs inside the system indicate the fault status of individual disk drives.

There are three LEDs (Activity, Fault, OK-to-remove) for each disk drive. The disk drive LEDs are located on the front of the disk cage, as shown below.

The disk drive LEDs are defined as follows:
