Provided is a control unit for displaying a network load sustained on a networking cable. The control unit requests a current network load of the networking cable from a monitoring circuit. The control unit receives the current network load from the monitoring circuit. The control unit instructs a visual indicator to display the current network load of the networking cable.

A method is provided that includes accessing, by a debugging device associated with an external user device, (i) a serial console of a hardware network device, and (ii) a management Ethernet port of the hardware network device. The method includes providing, by the debugging device, (i) a serial console interface from the serial console of the hardware network device to the external user device, and (ii) a management Ethernet interface from the management Ethernet port of the hardware network device to the external user device. The method includes receiving, by serial console interface and the management Ethernet interface of the debugging device, user input from the external user device. The method includes sending, using a hardware bypass in the debugging device. Ethernet management traffic from the hardware network device to the external user device through an internal network, responsive to the debugging device improperly operating.

A method and fiber optic coupling system are provided. The method includes establishing that a physical coupling has occurred between a fiber optic cable and a fiber optic Small Form-factor Pluggable (SFP). The fiber optic cable includes a cable magnetic connector. The fiber optic SFP includes a SFP magnetic connector having a plurality of magnetic switches. The fiber optic SFP is operably coupled to a SFP circuit board, an emitter, and a receiver. The method further includes determining that the cable magnetic connector has applied a magnetic field to the plurality of magnetic switches. The method further includes activating the emitter and the receiver, responsive to the magnetic field being applied to the plurality of magnetic switches.
