Estimating the term…
The invention relates to a PoE system, which comprises a powered device (2) and a power sourcing device (1). The power sourcing device comprises one or more ports (12) and the powered device is connectable to a port of the power sourcing device by an electrical conductor (13) for conveying the sourced power along with data. The powered device comprises an interface for providing a measure of its energy consumption within the PoE system and, if it does not have the ability to measure its energy consumption, is adapted to negotiate with the power sourcing device whether the power sourcing device has the ability to measure the energy consumption of the powered device and to provide the measured energy consumption to the powered device for provision via the interface. This can make the PoE system more flexible and allow for a single “point of contact” for providing energy usage feedback.
A PoE system, wherein the PoE system comprises:
A method for providing a measure of an energy consumption of a powered device in a PoE system comprising the powered device and a power sourcing device for sourcing a power to the powered device, wherein the power sourcing device comprises one or more ports and the powered device is connectable to a port of the power sourcing device by an electrical conductor for conveying the sourced power along with data, wherein the method comprises:
