Unit Identification Switches

There are two Unit Identification (UID) Switches on the motherboard. The Front Panel UID Switch is connected to Pin 13 of the Front Control Panel. The Rear UID Switch (SW1) is located next to LAN Port2. When you push the UID Switch on the Front Control Panel, both Rear UID and FP UID Indicators will turn on. Push the FP UID Switch (or the Rear UID Switch-SW1) again to turn off both Indicators. These UID Indicators provide easy identification of a system unit that may be in need of service. (*For more information on the FP UID Switch, please refer to FP UID Switch on Page 2-11.)

SGPIO Headers

There are two SGPIO (Serial General Purpose Input/Output) headers (J29, J30) located on the motherboard. These headers are used to "talk to" the AMI Chip on the backplane. See the table on the right for pin definitions. Refer to the board layout below for the locations of the headers.
