NOTE: Begin lifting the system board at the edge near the hard drive shield. The sheet metal may have to be deflected slightly to provide clearance for removing the board. Continue lifting the system board out toward the front of the computer.
Reverse the above procedure to install the system board.
IMPORTANT: When installing the system board, install the screws and standoff first but do not tighten them. This allows the alignment pins to properly position the board. Next, install the screwlocks, then tighten the screws and standoff. This procedure ensures proper alignment of the External Options Connector on the system board with the connector on the expansion base at docking.
