2-12 General Description

DISK ACCESS LED ( )

The DISK ACCESS LED indicates the status of the hard disk drive mounted in the 3.5-inch disk
bay.
The LED turns green each time access is made to the hard disk drive.
When the DISK ACCESS LED turns amber, it indicates that a hard disk drive failure has occurred.
Check the hard disk drive LED for the status of the failing hard disk drive.
IMPORTANT: If a hard disk drive in the server is connected to the
internal disk array controller (which is additionally mounted), the
access LED signal cable (connected to the connector on the mother
board) must be connected from the disk array controller to the mother
board.

ACT LED (

)
The ACT LED is green while the server is connected to the LAN. The LED 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 LED (UID)

Pressing the UID switch toggles the front panel UID LED (blue) and the mother board UID LED on
and off. The mother board UID LED 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 LED
The disk access LED of the floppy disk drive or CD-ROM drive is on while the drive is accessed.
