Confirming Servers (UID Switch)
Using Unit ID (UID) Switch helps you to identify the target server.
When the server is working, before you turn the server off or disconnect a cable from the server, be sure to
identify the target server by using UID Switch/LED first.
To turn UID LED on, press UID Switch. When it is pressed again, the LED will be off.
