Indicators
A rear Unit Identifier (UID) switch and a
rear UID LED (LE1) are located next to the
VGA port on the motherboard. The front UID
switch and the UID LED are both located on
the front panel control (JF1), with the front
UID switch on pin 13 of JF1 and the front
LED on pin 7. When you press either the
front or 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 identifica

Note:
UID can also be triggered via
IPMI on the motherboard. For more
