Abstract
Described herein are systems, devices, techniques and products for minimizing disruption to network systems due to false detection of a Power over Ethernet (PoE) Power Sourcing Equipment (PSE) as a Powered Device (PD). The disclosed systems, devices, techniques and products provide a way for a PSE to identify itself and avoid being detected as a legacy PD. The disclosed systems, devices, techniques and products further provide a way for a PSE to identify devices that do not require power from the PSE, such as another PSE or a device that is not a PD, and disable automatic PD detection, disable PoE, or otherwise prevent injection of power/current to the other device.
