To remove and replace the expansion interface board
HP 16501A
1
Using previous procedures, remove the following assemblies:
•
Bottom cover
•
All optional modules and filler panels
2 Disconnect the interface cable by pressing the release tabs on either side of the
cable connector while pulling the cable connector away from the board.
3 Disconnect 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.
4 Remove the two screws connecting the expansion interface board to the rear panel
of the expansion frame.
5 Carefully slide the expansion interface board out of the expansion frame.
6 Reverse 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.
