Abstract
A PoE power utilization method constituted of: detecting a first function of a voltage between a current path node and a current return path node during a first time period and during a second time period, the second time period different than the first time period; sensing a second function of the magnitude of a current flowing through the current path during the second time period; responsive to the detected first time period voltage function, the detected second time period voltage function and the sensed second time period current magnitude function, determining a third function of a resistance seen by the current path; and outputting an indication of the determined resistance function.
