Identifying Server (UID Switch)
Using UID (Unit ID) Switch helps you to identify the target server.
When the server is working,
be sure to identify the target server by using UID Switch first
before you turn
off the server or disconnect a cable from the server. The front and the rear UID LEDs work together.
To turn UID LED on, press UID Switch. When it is pressed again, the LED will be off.
