ABSTRACT
The article discusses ways on how to protect power over Ethernet (POE) systems from lightning surges and other electrical hazards. It is stated that increases have occurred in the amount of power that POE power-supply equipment (PSE) can deliver from 15.4 watts for POE to 30 watts for POE+ thereby, increasing the number of potential applications like powering VOIP telephony. it is indicated that in POE, PSE feeds power into the cable either through a switch called end span or through a midspan.
