Abstract:
1. A power over Ethernet system, comprising: a powered device detection component that detects a presence of a network device upon coupling of said network device to a power source equipment port via an Ethernet cable; a power controller that initiates a first delivery of power to said power source equipment port, said first delivery of power being restricted by a current limit that is assigned to said power source equipment port, said current limit being set to a first level during said first delivery of power; and an authentication component that receives authentication information from said computing device while said computing device receives said first delivery of power, said authentication component determining whether said received authentication information matches registered authentication data, wherein upon a determination that said received authentication information matches said registered authentication data, said power controller changes said current limit assigned to said power source equipment port to a second level that is higher than said first level, said current limit at said second level enabling a second delivery of power to said power source equipment port that is at a level higher than said first delivery of power, wherein said power controller ends a delivery of power to said power source equipment port if said authentication information does not match said registered authentication data.
