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. The UID switch is located at JUIDB1, which is next to the VGA
port on the back panel. The UID LED (LED1) is located next to the UID switch. When you
press the switch, the LED will be turned on, which provides easy identification of a system
unit that may be in need of service. Press the switch again to turn off the LED indicator.
Note: UID can also be triggered via BMC on the motherboard. For more information on BMC,
please refer to the BMC User's Guide posted on our website at
