Unit Identier Button/UID LED Indicator
A Unit Identier button and an LED indicator are located on the motherboard. The UID
button (JUIDB) is located next to the VGA port on the back panel. The UID LED is located at
UIDLED1, next to the UID button. When you press the UID button, the UID LED will be turned
on. Press the UID button again to turn off the LED indicator. The LED indicator provides easy
identication 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 https://www.
