Abstract:
A system for power distribution to network devices in a powered network is described herein. The system includes a first power sourcing equipment (PSE) device, which is configured to communicate data and selectively provide power to one or more devices. The system further includes a second PSE device coupled to the first PSE device through a network cable. The second PSE device is configured to communicate data, selectively provide power to one or more devices, and to receive a probing input through the network cable. The second PSE device includes a false detection mitigation circuit, which is configured to increase a leakage current of the second PSE device. The increased leakage current is associated with a resistive signature that is outside of a resistive range of a valid powered device.
