Abstract

The invention provides a power supply method, device and network equipment of the Ethernet. The power supply method comprises the following steps: a detection module detects the operation state of a POE (power over Ethernet) power, and acquires information of the POE power which is in the powered mode; a CPU (central processing unit) acquires the above-said information, and analyzes the information to get the number of the POE powers in the powered mode; the CPU judges whether the number of the powers equals to zero; when the number of the powers is judged to be non-zero, the CPU provides a total power value corresponding to the number to the POE module; and the POE module controls the power supply to the PD (power device) according to the total power value. By adopting the technical scheme in the invention, the efficiency and convenience of the POE power supply can be improved, the problem of power supply overcurrent due to the fact that users cannot change the total power value timely through the software when the number of the POE powers is changed in the prior art can be solved, and the safety of the POE power can be ensured.

Description

Technical field [0001] The present invention relates to communication electronic technology, in particular to an Ethernet power supply method, device and network equipment. Background technique [0002] Power Over Ethernet (PoE) technology is a technical solution that simultaneously transmits Ethernet data signals and DC power signals through a common Ethernet cable. In other words, POE refers to providing DC power supply capability to IP terminals while transmitting data signals to Internet Protocol (Internet Protocol; referred to as IP) terminals through Ethernet cables under the existing Ethernet cable wiring infrastructure. Among them, the IP terminal may be an IP telephone, a wireless local area network access point (Access Point; referred to as AP), a security network camera, etc. [0003] A complete POE system includes power source equipment (Power Source Equipment; referred to as: PSE) and powered equipment (Power Device; referred to as: PD); PSE is the manager of the POE ...
