Inserting a cable into the horizontal bottom contact connector
1
Check the actuator to verify it is in the open position.
2
Insert the cable into the ZIF connector with the contacts facing downward and away from the locking actuator. The
cable needs to be inserted below the actuator.
Note: Verify that the cable is installed squarely into the connector. If the cable is not squarely installed, then
intermittent failures could occur.
