Power device interface arranged to detect amount of power available

摘要

A powered device interface arranged as an interface between power received over a structured communication cabling and a powered device, the powered device interface constituted of: a class event counter; a logic circuit in communication with the class event counter; and a plurality of flag outputs each responsive to the logic circuit, each of the flag outputs associated with a predetermined powering level of a power sourcing equipment connected over the structured communication cabling, the logic circuit arranged to: output an active signal at the flag output associated with a detected powering level of the connected power sourcing equipment; and output an active signal at all other flag outputs associated with powering levels less than the detected powering level of the connected power sourcing equipment.
