Unit Identier Switch/UID LED Indicator
A Unit Identier (UID) switch and an LED In-
dicator are located on the motherboard. The
rear UID switch is located next to the VGA
port on the back panel. The front UID switch
is located on Pin 13 on the Front Panel
Control (JF1). The rear UID LED (LE1) is
located next to the UID switch and the front
UID LED is located on Pins 7 on JF1. When
you press the UID switch, the UID LED will
