Unit Identifi cation Switches
There are two Unit Identification (UID)
Switches on the motherboard. The Front
Panel UID Switch is connected to a pin in
the Front Control Panel (JF1). The Rear UID
Switch (SW1) is located next to Fan6. When
you push the UID Switch on the Front Control
Panel, both Rear UID and Front Panel UID
Indicators will be turned on. Push the FP UID
Switch or the Rear UID Switch-SW1 again to
turn off both Indicators. These UID Indicators
provide easy identifi cation of a system unit
