Unit Identifier Switch/LEDs (On the I/O
Module)
A Unit Identifier (UID) switch on the AOM-
X10QBi-A/L I/O module, and two LED indica-
tors are located on the baseboard. The UID
switch is located next to the LAN ports on
the I/O module. The rear UID LED (LED28)
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 pins 7/8 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 identifica-
tion of a system unit that may be in need of
service.
Note:
UID can also be triggered
via the IPMI on the system moth-
erboard. For more information on
the IPMI, please refer to the IPMI
User's Guide posted on our website
