System and method for policing bad powered devices in power over ethernet

摘要

A system and method for policing bad powered devices in power over Ethernet. Degradation of components within powered devices can lead to noise and ripple that exceed specified thresholds. This noise and ripple can adversely impact the operation of the power sourcing equipment. A noise detector implemented in the power sourcing equipment can detect the presence of such noise and ripple and modify the application of power to the particular port.
