METHOD FOR MITIGATING FALSE POWERED DEVICE DETECTION
First Claim
1. A power sourcing equipment (PSE) device for use in a powered network, comprising:
- a PSE controller integrated circuit;
a power rail;
a plurality of network ports configured to communicate data, selectively provide power to one or more devices through a plurality of network cables, and to receive a probing input through a network cable of the plurality of network cables, the plurality of network ports coupled to the power rail;
a power supply circuit coupled to the power rail; and
a false detection mitigation circuit coupled to the power rail, the false detection mitigation circuit configured to increase a leakage current of the PSE device, wherein the increased leakage current is associated with a resistive signature that is outside of a resistive range of a valid powered device.

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.
