Unit Identier Switch
A Unit Identier (UID) switch is located
next to the VGA port. The Rear UID
LED (LED1) is located next to the UID
switch. The front UID LED connects
to pin 7 of the JF1 header. When you
press the UID switch, both front and
rear UID LED indicators will be turned
on. Press the UID switch again to turn
off both LED Indicators. These UID
Indicators provide easy identication
of a system unit that may be in need
of service.
Note: UID can also be triggered via
IPMI on the serverboard. For more
information on IPMI, please refer to
the IPMI User's Guide posted on our
website at http://www.supermicro.com.
