Abstract
The present disclosure discloses a method and an apparatus of power over Ethernet, and belongs to the field of communications. An Ethernet power sourcing equipment sets a power supply port to a sleep state, and sets a timer for the power supply port; enables the power supply port when the timer reaches a set time; and detects whether a powered device PD is connected to the power supply port, and if a PD is connected to the power supply port, triggers the power supply port to supply power to the PD; if no PD is connected to the power supply port, resets the power supply port to the sleep state, and sets the timer for the power supply port. Implementation of the present disclosure effectively reduces power consumption of the system and saves energy.
