Unit Identifier Switch
A Unit Identifier (UID) Switch and two LED
Indicators are located on the motherboard. The
UID Switch is located next to the LAN ports on
the backplane. The Rear UID LED (LED3) is
located next to the UID Switch. The Front Panel
UID LED is located at pins 7/8 of the Front
Control Panel at JF1. Connect a cable to pin
8 on JF1 for Front Panel UID LED indication.
When you press the UID switch, both Rear UID
LED and Front Panel UID LED Indicators will be
turned on. Press the UID switch again to turn
off both LED Indicators. These 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.supermicro.
