ABSTRACT:
A system delivers power to a powered device through a local area network using a power sourcing equipment to process data of an interconnected network and to receive power from a first power source coupled to the power sourcing equipment. The system may include a powered device coupled at a distance away from the power sourcing equipment through a local area network (LAN) to process the data of the interconnected network through the power sourcing equipment. The powered device may include a modular power over LAN circuit to enable power to the powered device through the LAN when the modular power over LAN circuit is coupled to the powered device.
