Abstract
Presented herein are techniques for storing parameter values determined by a power sourcing equipment (PSE) device during a Power over Ethernet (PoE) detection process. More specifically, in one example, a voltage is applied to an end device connected, via an Ethernet cable, to a port of the PSE device. The PSE device measures the current drawn by the end device and calculates, based on the measured current, a resistance and/or a capacitance value for the end device. The resistance and/or capacitance values are then stored in a memory of the PSE device.
