Unit Identier Switches/UID LED
Indicators
A rear Unit Identier (UID) switch and a
rear UID LED (LE1) are located next to the
VGA port on the motherboard. The front
UID switch and the front UID LED are both
located on the Front Panel Control (JF1)
(with the front UID switch on pin 13, and
the front LED on pin 7 of 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 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 @http://www.super-
