A Unit Identifier button (JUIDB), a
backplane LED indicator and a front
panel UID header are provided on
the motherboard. The UID button is
located next to the VGA port on the
backplane. The rear UID LED indicator
(LED1) is located next to the UID but-
ton. The front panel UID LED header
is located at pins 7/8 of JF1. Connect a
cable to pin 8 on JF1 for the front panel
UID LED connection. When you press
