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 at UID SW, which is next to the Display Port on the back panel. The UID
LED 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
