Unit Identifier Switch/UID LED Indicator

on the rear side of the system. The front UID LED is located on Pin 7 of the Front Control
Panel (JF1). When you press the UID switch, both front and rear UID LED indicators will be
turned on. Press the UID switch again to turn off the LEDs. The UID Indicators provide easy
identification of a system unit that may be in need of service.
