2-36 General Description
Identification of Servers (UID Switch)
An "UID (Unit ID) lamp" is provided on the front panel and rear panel. If more than one server is
mounted in a single rack, the lamp identifies the server you are going to maintain.
The UID lamp goes on 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.
