Unit Identifier Switches/UID LED
Indicators
A rear Unit Identifier (UID) button (JUIDB1)
and a rear LED (LE1) are located close to
LAN 2 port on the rear side of the mother-
board. The front UID switch is located at pin
13 of the Front Control Panel (JF1), while
the front UID LED is located on pin 7 of JF1.
When you press the front UID switch or the
rear one, both front and rear UID LEDs will
be turned on. Press the UID button again to
turn off the LED indicator. The UID Indicators
provide easy identification 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-
micro.com.
