Appendix B 

Connector Pin Assignments

This appendix describes the system board connector pin assignments.

Table B-1 lists the connectors and sockets on the system board. The table also cross-
references the page numbers where the connectors and their pinouts are described.
Table B-2 and Table B-3 list each connector by its function, number, and type.

Figure B-1 shows the locations of the connectors and slots on the system board.
Figure B-2 shows the locations of the connectors on the back of the system unit.
