Identifying Server (UID Switch)
Using Unit ID (UID) Switch helps you to identify the target server from several servers in one rack.
When servers are running on a rack, before you turn the server off or disconnect a cable from the server, be
sure to identify the target server by using UID Switch first.
To turn UID LED on, press UID Switch. When it is pressed again, the LED will be off.
