Abstract

A power control subsystem for controlling the supply of power transmitted to at least one node over communication cabling, the power control subsystem comprising circuitry to control current of a power transmitted over communication cabling, the circuitry being operative to provide current limiting for the power at a first threshold, and delayed over current cut-off of the power at a second threshold, the second threshold being lower than the first threshold.
