Abstract
A method for controlling the output power of power sourcing equipment powering a device through an ethernet cable, comprising: performing a power negotiation between the power sourcing equipment and the powered device, the negotiation comprising establishing a relation between an output voltage of the power sourcing equipment and a loop current from the powered device to the power sourcing equipment by measuring the loop current in a current-sensing device; obtaining indications of whether the powered device needs increased power and whether the power sourcing equipment is able to deliver increased power; if the powered device needs increased power and the power sourcing equipment is of a power sourcing equipment type able to deliver increased power, physically manipulating the current-sensing device such that it senses a manipulated lower loop current; and providing a manipulated higher output power from the power sourcing equipment to the powered device.
