You can turn on or off UID LED in either of following two ways:

UID LEDs on the target server (front and rear). Press it again to turn off the LEDs.
(2) Press the UID switch on server.
When the location of target server is known and you need to work with the server from rear side,
press the UID switch on front panel. The UID LEDs on front and rear panel go on. You can
identify the target server by viewing the LED on rear panel. Similarly, press the UID switch on
