Abstract:
A power source equipment is configured to provide a power to a powered device in a power over Ethernet. The power source equipment includes a first port, a second port, and a control circuit. The first port is configured to perform a power classification on the powered device, and provide a first voltage to the powered device in a first stage. The second port is configured to provide a second voltage to the powered device in a second stage. The control circuit is configured to disable the second port in the first stage, and configured to control the second port to output the second voltage and increase the first voltage in the second stage.
