Unit Identifier Switches

Two Unit Identifier (UID) Switches and LED Indicators are located on the motherboard. The Front Panel UID Switch is located at Pin 13 on the Front Control Panel (JF1). The Rear UID Switch is located at SW1 next to the VGA connector on the back panel. The Front Panel UID LED is located at Pin 7 of JF1, and the Rear UID LED is located at LE4. When you press a UID switch on the front panel or on the back panel, 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 identification of a system unit that may be in need of service.

		Note: UID LED is supported by the
		physical switch or the BMC. When it
		is controlled by the physical switch, it
		will stay solid. When it is controlled by
3	1	the BMC, it will blink.
