Abstract: Methods for operating a power transmitter and a power receiver to enable selection of one of a plurality of power modes in a coordinated manner, as needed by a power receiver. The plurality of power modes may include fault managed power modes at different voltages, at least one non-fault managed power mode and an alternating current (AC) power mode.

Abstract: A power transceiver with bi-directional fault managed power is provided that enable role reversals and fault detections. Specifically, a method is provided in which a first power transceiver detects whether a fault is present on one or more wires. The first power transceiver is configured to transmit power over the one or more wires from a power source device to a second power transceiver. The method further includes determining whether the fault is an intentional fault generated by the second power transceiver and controlling the first power transceiver to switch to a receiver mode for receiving the power over the one or more wires from the second power transceiver based on determining that the fault is the intentional fault.

Abstract: A network interface device operates in a normal operating mode in which the network interface device continually receives transmission symbols via a communication link. The network interface device determines that the network interface device is to transition to a low power mode, and in response transitions receiver circuitry to the low power mode. During a transition time period corresponding to determining that that the network interface device is to transition to the low power mode, the network interface device ignores signals received via the communication link.

Abstract: Presented herein are techniques for preventing an electrical arc upon disconnect of a network cable. A method can include monitoring a network cable connected to a device for faults at a remote location from a connector of the network cable by observing conditions on the network cable of power applied to the network cable, wherein the network cable is for sending data and power. The method can further include detecting a fault on the network cable, wherein the fault was introduced intentionally at the connector prior to disconnecting the connector from the device. The method can further include terminating power at the remote location that is sent over the network cable to prevent an electrical arc upon disconnecting the connector from the device.
