[3]  The A-Board is mated to the D-Board by four flexible connectors: A4, A5, A6 & A7 (D4, D5, D6 & D7 on the D-Board, respectively).

• To remove either boards, unplug the connectors on the A-Board.
• Some tie-wraps that secure the wire dressings may need to be unfastened for chassis removal.

D-BOARD GROUND CONNECTOR

• To release the GND cable from D13 connector insert a wire in both cavities of connector, then pull up the cable.
