Unit Identifier Switch/UID LED Indicator
A Unit Identifier (UID) switch and an LED indicator are located on the motherboard. The UID
button is located at UID, on the back panel. The UID LED (LED2) is located next to the UID
switch. When you press the UID switch, the UID LED will be turned on. Press the UID switch
again to turn off the LED indicator. The UID Indicator provides easy identification of a system
unit that may be in need of service.
Note: UID can also be triggered via IPMI on the motherboard. For more information
on IPMI, please refer to the IPMI User's Guide posted on our website at
supermicro.com/support/manuals/.
