  • Power status telemetry for powered devices in a system with power over ethernet
    Patent number: 11936485
    Abstract: A powered device interface assembly includes an optocoupler and a powered device interface. The opto-coupler is electrically coupled with a microcontroller of the power device interface. The powered device interface includes a telemetry circuit coupled with the opto-coupler and configured to generate encoded telemetry information for output via a single pin of the powered device interface for transmission to the microcontroller of the powered device, wherein the opto-coupler is coupled with the single pin and is configured to electrically isolate the single pin from the microcontroller.
    Type: Grant

  • Power control of powered devices in a system with power over the ethernet
    Patent number: 11689377
    Abstract: A powered device interface includes a supply sensing circuit, a demand sensing circuit, and a control circuit. The supply sensing circuit is configured to sense an amount of power received by the powered device from at least one power source equipment over an ethernet cable. The demand sensing circuit is configured to sense a power demand requested by the powered device. The control circuit is coupled with the supply sensing circuit and the demand sensing circuit and is configured to cause the power demand requested by the powered device to be reduced when the power demand requested by the powered device exceeds the amount of power allowed by the power source equipment for the powered device.
