2-12 General Description
DISK ACCESS Lamp ( )
The DISK ACCESS lamp indicates the status of the hard disk mounted in the 3.5-inch disk bay.
The lamp turns green each time access is made to the hard disk.
When the DISK ACCESS lamp turns amber, it indicates that a hard disk failure has occurred.
Check the hard disk lamp for the status of the failing hard disk.
IMPORTANT:
If a hard disk in the server is connected to the internal
disk array controller (which is additionally mounted), the access lamp
signal cable (connected to the connector on the mother board) must be
connected from the disk array controller to the mother board.
ACT Lamp ( )
The ACT lamp is green while the server is connected to the LAN. The lamp flashes while the
server is accessed via the LAN (during transmission/reception of packets). The number next to the
icon indicates the network port number on the rear panel of the server.
UID Lamp (UID)
Pressing the UID switch toggles the front panel UID lamp (blue) and the mother board UID lamp on
and off. The mother board UID lamp is visible through the rear of the chassis and allows you to
locate the server you're working on from the rear of the servers on a rack.
Disk Access Lamp
The disk access lamp of the floppy disk drive or CD-ROM drive is on while the drive is accessed.
