Abstract

The invention discloses power over Ethernet method and device, and belongs to the field of communication. A power supply port is arranged in a sleep state by a power over Ethernet device, and a timer is arranged at the power supply port; the timer enables the power supply port when achieving a set time; a powered device (PD) is detected whether to be connected into the power supply port, when the PD is connected into the power supply, the power supply port is triggered to supply power for the PD; and when no PD is connected into the power supply port, the power supply port is set to be in the sleep state again, and the timer is arranged at the power supply port. By implementing the power over Ethernet method and device, the electric consumption of a system can be effectively reduced, and the energy can be saved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a method and device for powering over Ethernet. Background technique [0002] Power over Ethernet (English: Power Over Ethernet, referred to as: POE) refers to the power supply for some IP-based terminals (such as IP phones, wireless LAN access) without any changes to the existing Ethernet wiring infrastructure. point AP, network camera, etc.) while transmitting data signals, it can also provide DC power supply technology for such devices. The PoE system includes a power supply equipment (English: Power sourcing equipment, PSE for short) and a powered device (English: Powered device, short: PD). [0003] At present, PoE technology is more and more widely used in people's lives, the proportion of PoE ports in Ethernet electrical switches continues to increase, and the types of devices supported by PoE are becoming more and more abundant.
