Abstract

The invention discloses a method for power over Ethernet. Power sourcing equipment acquires power sourcing information of Ethernet ports, and the power sourcing information includes the state of powered devices; if the state of the powered devices of the Ethernet ports is ineffective, the powered devices connected with the power sourcing equipment via the Ethernet ports are detected, and when the powered devices are ensured to be effective powered devices, the state of the powered devices of the Ethernet ports is set to be effective and the powered devices are powered on; and if the state of the powered devices of the Ethernet ports is effective, the powered devices are directly powered on so that rapid power-on and starting of the powered devices can be realized. The invention also provides the power sourcing equipment and a system for power over Ethernet.

Description

technical field [0001] The invention relates to the field of network communication, in particular to an Ethernet power supply method, a power supply device and an Ethernet power supply system. Background technique [0002] Power over Ethernet (English: Power over Ethernet, abbreviation: PoE) equipment includes power supply equipment (English: power sourcing equipment, abbreviation: PSE) and powered equipment (English: powered device, abbreviation: PD). The power supply equipment can provide different powers to the power receiving equipment, such as 15.4 watts (English: watt, symbol: W), 30W, etc. [0003] In recent years, PoE technology has been more and more widely used, and the types of powered devices have become more and more abundant. Many powered devices require a power-on start-up time of less than 100 milliseconds to improve customer experience. However, the power-on process of the power supply device to the powered device is relatively complicated. As a result, the...
