A connector connection verification system includes a cable connector and a networking device. The networking device includes a port system defining a port and including a networking device connector, and at least one cable connector sensor device that is located adjacent the port. The cable connector sensor device(s) detects that the cable connector is inserted in the port defined by the port system while the cable connector does not mate with the networking device connector included in the port system and, in response, transmits an incorrect connection signal that indicates that the cable connector is incorrectly connected to the port system. A management interface provided on the networking device may receive the incorrect connection signal from the cable connector sensor device(s), and provide information that describes the cable connector and that indicates that the cable connector is incorrectly connected to the port system for display on a display device.
