Unit Identifi er Switch/UID LED
Indicator
A Unit Identifi er (UID) switch and an
LED indicator are located on the moth-
erboard. The UID switch is located next
to the VGA port on the backplane. The
UID LED (LE4) is located next to the
UID switch. When you press the UID
switch, the UID LED will turn on. Press
the UID switch again to turn off the LED
indicator. The UID Indicator provides
easy identifi cation of a system unit that
may be in need of service.
Note: UID can also be triggered via
IPMI on the motherboard. For more
