Cisco Systems Jackscrew installation instructions Installing the Screw-Type Lock

Step 4: Repeat steps 2 and 3 for all addition ports that require jackscrews.

Step 5: Place the removed brackets and slotted screws aside; you can discard them after the jackscrews are installed, and the installation is complete.

Installing the Screw-Type Lock

Use the hardware provided in the replacement kit to reinstall the connector. Do not use any of the hardware you removed from the slide-type lock bracket.

Step 1: Ensure that the slide-type lock bracket, shown in Figure 5, has been removed from the connector port.

Step 2: Insert a lock washer onto the shaft of a jackscrew and push it up to the head of the jackscrew.

Step 3: Insert the jackscrew into one of the threaded holes on the connector. Turn the jackscrew clockwise about two full turns to thread it into the hole.

Step 4: Repeat steps 2 and 3 for the second jackscrew and lock washer, placing the second jackscrew in the other threaded hole on the connector. Turn the jackscrew clockwise about two full turns to thread it into the hole.

Step 5: Observe both jackscrews edge-on and turn them another half turn to ensure they are threaded properly.

Step 6: Use the 3/16-inch nut driver to tighten the jackscrews in the connector. Do not overtighten the screws; the lock washer will secure the jackscrews in place, and the thumbscrews on the cable connector, when inserted and tightened, will further tighten the jackscrews.

Step 7: Repeat steps 1 through 6 for all addition ports that require jackscrews.

Step 8: Proceed to the next section to check the installation.
