IDENTIFICATION OF SERVERS ~ UID SWITCH ~

A UID (Unit ID) LED is provided on the front panel and rear panel. If more than one server is

mounted in a single rack, the LED identifies the server you are performing maintenance on.

The UID LED turns on or blinks when the UID (Unit ID) switch on the front panel is pressed. It

goes off when the switch is pressed again.

Maintenance from the rear of the rack has to be carried out in a dark, narrow space. The interface

cable of a server or power supply unit in normal state may be disconnected by accident in this

situation. To prevent this problem, you should start maintenance after confirming the target server

by using the UID switch.
