Abstract
An Ethernet power sourcing equipment (PSE) and a power management method thereof are provided. The Ethernet PSE includes a plurality of ports and a controller. Each port is coupled to a powered device (PD), to supply power to the PD through the port when the PD is in a power supply stage. When the PD enters a startup stage before the power supply stage, the controller calculates a remaining power quota based on a power quota allocated to the PD.
