Systems and methods for powering a power-over-ethernet powered device using multiple power-over-ethernet sourcing devices

Abstract:

Systems, methods, and apparatuses are provided herein for implementing a PoE system comprising a plurality of power sourcing equipment that power a single powered device. Control circuitry may determine the power necessary to operate a powered device in a first power mode, and may cause the powered device to draw, from a first power sourcing device, to a first port of the powered device, a first wattage. The powered device may draw, from a second power sourcing device, to a second port of a powered device, a second wattage, where a sum of the first and second wattage equals the amount of power necessary to operate in the first power mode, wherein a first isolation boundary isolates the first power sourcing equipment, the first Ethernet link, and the first port, and wherein a second isolation boundary isolates the second power sourcing equipment, the second Ethernet link, and the second port.
