Problems solved by technology

[0003] However, in practical applications, due to the limited maximum Powerbank supported by the existing PSE board (also known as PSE power management chip), in the face of increasingly complex and diverse PDs (Powered Devices, powered equipment), the power supply system proposed Higher and more flexible power requirements, the power modules provided by existing switches are far from meeting these power requirements

Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] A switch generally includes a main control board and a PSE board. The main control board can be provided with a power slot for external power supply. In an existing switch, a record is usually statically configured on the PSE board to indicate that the PSE board can provide The power table that outputs the maximum power. These power values ​​are the maximum power values ​​that can be provided to the PSE board obtained by combining different types of power modules supported. The power table includes the Power bank ID of the power bank and the written data corresponding to each Power bank ID. The input power combination can be assigned to the bank value of the maximum power value of the PSE board. For example, the PSE board supports a maximum ...

Abstract

The invention provides a power supply method and device, and equipment, and the method comprises the steps: writing the maximum power provided by a power supply module into a bank represented by a Power bank ID corresponding to a power supply slot on a PSE board according to the detected condition whether the power supply slot of a main control board is connected with the power supply module and the type of the power supply module, and instructing the PSE board to select the written power in the bank represented by the Power bank ID as the maximum power to supply power according to the condition whether the power supply slot of the main control board is connected to the power supply module, so that the main control board can detect the power supply module inserted into the power supply slot in real time and the type of the power supply module, and the PSE board is instructed to provide diversified banks represented by the Power bank ID of the written power so as to supply power, so that diversified power requirements can be met.

Description

technical field [0001] The present application relates to the technical field of switches, in particular to a power supply method, device and equipment. Background technique [0002] At present, in the switch, the PSE (Power Sourcing Equipment, power supply equipment) board is generally statically configured with a power meter to represent the maximum output power value of the PSE board. These maximum power values ​​are the maximum power corresponding to different power modules. Combined and written to the bank indicated by several Power bank IDs on the PSE board, in order to configure the prepared power meter to the PSE board through the communication bus (serial port) during the startup process to control the PSE board to determine The power recorded in the bank represented by which Power bank ID is used as the current maximum output power for power supply. [0003] However, in practical applications, due to the limited maximum Powerbank supported by the existing PSE boar...
