Abstract: Systems and methods are provided for a power distribution device having a power input and a plurality of power receptacles. The power receptacles are coupled in parallel with each other. A switching circuit is coupled between the power input and the power receptacles. A circuit breaker detects when an aggregate current load of the receptacles is greater than a rating of the circuit breaker. The circuit breaker disconnects the power input from all of the receptacles after a first amount of time following the detection. An electronic controller is configured to disconnect a subset of the receptacles from the power input with the switching circuit to reduce the aggregate current load below the rating of the circuit breaker within a second amount of time following the detection. The second amount of time is less than the first amount of time.

Abstract: A keyboard-mouse-video (KVM) system. The system includes a KVM switch having a first controller; a ROC unit having a second controller; and a cable which connects the ROC unit to the KVM switch, the cable having four pairs of wires. The first controller is configured to transmit and the second controller is configured to receive an Ethernet signal using a first pair of wires. The second controller is configured to transmit and the first controller is configured to receive a serial signal using a second pair of wires.
