Inserting a cable into the horizontal top contact connector
1
When installing the cable, check the locking actuator to ensure it is in the unlocked position. The tabs on
the ends of the actuator are vertical when the actuator is unlocked.
2
Insert the cable with the contacts on the cable facing up. Insert the cable on top of 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.
