Attach Cables

The connectors include a latching mechanism. The latching and unlatching mechanism varies

by manufacturer, and prior to installing cables, familiarize yourself with how to engage and

disengage the latch.

If the cable plug is not properly oriented to fit onto the port receptacle (as you attempt to insert

the cable in the port), do not twist the plug to achieve the correct orientation. Instead, reach back

a few feet on the cable, and twist the bulk cable to allow the plug to rotate to the proper orientation.

Doing this prevents the rotational forces from acting right at the plug terminations.

Attach cables to switches and HCAs assuring that the latch is engaged on each connection. Pull

or push evenly across the width of the lanyard to latch or unlatch the plug connector. Pulling

abruptly on the lanyard, or pulling on only one side of the lanyard will prevent the latch/unlatch

operation from occurring, and could damage or break the lanyard.

Care should be taken such that the mounting of the cable to switch or adapter does not place

unnecessary stress on the connection as depicted below:
