Problems solved by technology

[0006] Traditional POE equipment is controlled by a single-chip microcomputer or not controlled at all, which is not easy to manage, cannot be intelligently controlled, and lacks flexibility
Moreover, when using the controller, since a single 48V DC power supply is used, a special DC-DC power module needs to be added on the board to provide the controller with a low-voltage working voltage, the design is complex and the efficiency is low.

Embodiment 1

[0033] Embodiment 1 of the present invention is described by taking POE serial port management as an example. Figure 4 In the schematic diagram of using MCU and serial port to manage POE, the Ethernet switch part is composed of CPU and Ethernet switch chip, and the CPU is dedicated to the Ethernet switch chip. Although there is a Gigabit connection between the Ethernet switch chip and the backplane, it has nothing to do with POE management. The Ethernet power supply part is composed of a POE controller and a POE output circuit. The management interface of the POE controller is managed by the MCU on the low-voltage side after being isolated by the optocoupler. The MCU communicates with another board through the serial port on the front panel. The power output by POE comes from the 48V DC connector on the front panel. The Ethernet switching part and the POE part share the same POE transformer and the same output connector. The POE external management interface on the board ca...

Embodiment 2

[0036] Embodiment 2 of the present invention is described by taking POE gigabit management as an example. Figure 6 As shown, the POE management part and the Ethernet switch share a CPU, and the POE management data is transmitted from the backplane through the Gigabit port of the Ethernet chip by the CPU. The front panel only provides the service interface of POE power output and the 48V DC power interface of POE. The Ethernet part and POE part in the figure are implemented on an AMC board, which realizes the Ethernet switch with Power over Ethernet function.

[0037] Figure 7 Describes the structure diagram of managing POE through the Gigabit port, specifically: the POE part is managed by the CPU of the Ethernet switch, and the CPU is connected to the backplane through the Gigabit port of the Ethernet chip. If the Gigabit ports are interconnected, when it is necessary to manage the POE or query the POE status, the management data will be sent from the 100M network port on ...

Abstract

The present invention relates to a POE system realized on MicroTCA and its management method, including simultaneously realizing Ethernet function and Ethernet power supply function on a plug-in board card; utilizing a microprocessor and its serial port to manage POE through another board card ; Or directly use the CPU to manage POE, and manage the management data in the form of IP packets through Gigabit and 100M Ethernet ports for management; through the combination of two PD-side POE controllers, high-power power supply is realized. The POE system has good module scalability and management intelligence, which simplifies system design.

Description

technical field [0001] The invention relates to the technical fields of network communication and Ethernet power supply, in particular to a POE system and a management method thereof realized on an AMC board of a microtelecom computing framework MicroTCA standard platform. Background technique [0002] POE (Power Over Ethernet) is a technology that provides DC power to powered devices while using twisted-pair wires to transmit Ethernet data. [0003] MicroTCA (Micro Telecommunications Computing Architecture) is a specification formulated by the PICMG standardization organization. It is a new generation of super-performance general-purpose business processing platform built with standardized, modular and open design ideas. [0004] With the wide application of POE technology, more and more POE devices have appeared. In the traditional design, the AMC board of the MicroTCA platform uses a single 12V load power from the backplane, and is restricted by the board area and space. ...
