Abstract
A power over Ethernet apparatus is provided. The power over Ethernet apparatus includes a power sourcing equipment (PSE) controller, a main chip and a redundant controller. The PSE controller is for power allocation among ports of the power over Ethernet apparatus. The main chip is coupled to the PSE controller through a first branch and for controlling the PSE controller. The redundant controller is coupled with the main chip, and coupled to the PSE controller through a second branch to control the PSE controller when the main chip stops sending a heart-beat signal. Methods of power over Ethernet are also provided.
