1Using previous procedures, remove the following assemblies:

•Bottom cover

•All optional modules and filler panels

2Disconnect the interface cable by pressing the release tabs on either side of the cable connector while pulling the cable connector away from the board.

3Disconnect the two cables on the expansion interface board. One cable is connected to the front-panel LED and one cable is connected to the mother board.

4Remove the two screws connecting the expansion interface board to the rear panel of the expansion frame.

5Carefully slide the expansion interface board out of the expansion frame.

6Reverse this procedure to install the replacement expansion interface board.

In order to ensure correct connection of the interface cable, the 68-pin "D" connectors on the cable are asymmetric in shape. They only fit into the ports on the boards when oriented to match the shape of the ports.

When reconnecting the interface cable, make sure the cable connector is properly seated into the port on the expansion interface board by pulling the cable connector without pressing the release tabs. If the connector is properly seated, it will remain connected to the port.
