Front LED indicators

The front of the system contain 12 disk drive status LEDs that are normally blue, and blink when there is activity on the disk. The LEDs are shaped like triangles, and the apex of the triangle points left or right, indicating that disk's status. If the disk drive has a failure, the disk’s status LED turns from blue to amber, indicating that a drive must be replaced.

The front also contains two system status LEDs. A blue system power LED is present that is on whenever the system has power. An amber system fault LED is also present that is normally off and lit amber whenever the chassis or any other FRU in the system requires service.
