Unit Identifier Switch/UID LED Indicator
A Unit Identifier (UID) switch and a rear UID LED (UID-LED) are located on the I/O backpanel.
A front UID switch is located on pins 7 & 8 of the front control panel (JF1). When you press
the front or the rear UID switch, both front and rear UID LEDs will be turned on. Press the
UID switch again to turn off the LED indicators. The UID indicators provide easy identification
of a system that may be in need of service. (Note: UID can also be triggered via IPMI on
the motherboard. For more information, please refer to the IPMI User's Guide posted on our
website at http://www.supermicro.com.)
