Unit Identifier Switch/UID LED Indicator
A Unit Identifier (UID) switch and a rear UID LED (LE1) are located on the rear side of the
motherboard. When you press the rear UID switch, the rear UID LED (LE1) will be turned
on. Press the UID switch again to turn off the LED indicator. The UID indicator 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
