General Description 2-17
Identification of Servers ~ UID Switch ~
An "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 going to maintain.
The UID LED goes on when the UID (Unit ID) switch is pressed. It goes off when the switch is
pressed again.
The UID LED blinks upon reception of command from software.
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.
