Abstract: A method is provided to conserve power in a power sourcing equipment (PSE) that provides a PSE port voltage at PSE ports. The method includes, in response to detecting a powered device (PD) is connected to the PSE port, providing a power supply output voltage at a default value and turning on the PSE port. After turning on the PSE port, the method includes determining the PSE port voltage. When the PSE port voltage is greater than a threshold value, the method includes decreasing the power supply output voltage.
