Front LED indicators
The front of the system contains 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 either left or right toward the disk whose status it represents. If the
disk drive has a failure, the disk’s status LED turns from blue to amber.
There are two square-shaped system LEDs. A blue system power LED is on whenever the
system has power. An amber system fault LED is normally off and is lit amber whenever
the chassis or any other FRU in the system requires service.
