4.Remove the long screw (if present) from the 50-pin cable. Discard this screw.

5.Remove the two cable-fastening screws from the Security Module shipping carton.

6.Attach the 50-pin cable connector to the 50-pin connector on the front of the module.

7.Install the two screws in the top and bottom screw holes of the

50-pin cable connector to secure the cable to the module connector as shown in Figure 3-5. (Only one of the cable-fastening screws may be installed depending on the angle of the 50-pin cable connector.)
