Unit Identifier Switch/UID LED Indicator
A Unit Identifier (UID) switch and an LED indicator are located on the motherboard. The UID
switch is located next to the VGA port on the back panel. The UID LED is located at LED1,
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 LED 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/.
