Unit Identifier Switch
A Unit Identifier (UID) Switch and
two LED Indicators are located on
the serverboard. The UID Switch is
located next to the 10G_LAN 4 port
on the backplane. The Rear UID
LED (LE2) is located next to the UID
Switch. The Front Panel UID LED is
located at Pins 7/8 of the Front Con-
trol 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.
