2-38 Setting Up the System
DISK ACCESS Lamp ( )
The DISK ACCESS lamp indicates the status of the hard disks mounted in the
3.5-inch disk bay. The lamp flashes green each time access is made to the hard
disks in your system. The location of this indicator is shown in Figure 2-35, F.
When the DISK ACCESS lamp turns amber, it indicates that a hard disk failure
has occurred. Check the hard disk lamp located on each hard disk to determine
the failing drive.
Note:
If a hard disk in the server is connected to a disk array
controller, the access lamp signal cable must be connected from the disk
array controller to the system board.

Pressing the UID switch located on the front panel (see Figure 2-35, Y) toggles

to locate the server you're working on from the rear of the servers in a rack. The
location of the rear panel UID lamp is shown in Figure 2-36, N.
