Problems solved by technology

The number of problems with the management board in the board-making process of the foundry increases accordingly. The main problems are that the management board has false soldering or the management board monitors the fan control board, the node mid-board and the link of the power supply unit. These functional problems are difficult to locate and solve quickly, which affects the production efficiency of large servers and rack cabinets
With the increase of functions and devices on the management board, it also increases the difficulty of locating and solving the problems of the management board after leaving the factory. Once the management board fails, the traditional method is to send the management board back to the foundry for problem location and solution. This solution requires a long period of time and seriously affects the production of cabinets
[0004] This traditional method of detecting and solving management board failures has been unable to meet the rapidly increasing usage of management boards.

Embodiment 1

[0021] A method for on-line detection of the management board of the present invention, the content of the online detection of the management board includes: detecting whether the power supply unit of the management board, the node middle board and the fan control board are in or not; Links, communication links between the management board and the fan control board, and the connectivity of the communication link between the management board and the node mid-board; complete the detection of the function of the management board.

Embodiment 2

[0023] A method for on-line detection of the management board of the present invention, the content of the online detection of the management board includes: detecting whether the power supply unit of the management board, the node middle board and the fan control board are in or not; Links, communication links between the management board and the fan control board, and the connectivity of the communication link between the management board and the node mid-board; complete the detection of the function of the management board.

[0024] Power supply unit detection on the management board: the initial level state of the GPIO port of the power supply unit is high level, and it becomes low level after connecting the power supply unit; during detection, if it is displayed as above, the power unit detection passes, otherwise the power unit detection fail.

[0025] On the management board, the mid-node mid-board is detected: the initial state of the absent signal of the mid-node mid-...

Abstract

The invention discloses a management mainboard online detection method and belongs to the technical field of management mainboard detection. The management mainboard online detection method comprises the steps of respectively detecting whether a power unit, a node middle plate and a fan control board of a management mainboard are in the state; detecting communication conditions of a communication link between the management mainboard and the power unit, a communication link between the management mainboard and the fan control board and a communication link between the management mainboard and the node middle plate; completing detection on functions of the management mainboard. Compared with the prior art, the management mainboard online detection method can detect the functions of the management mainboard effectively, convenience is brought to a production contract factory of the management mainboard to detect whether the functions of the management mainboard are good, and the failure rate after the management mainboards leave the factory is reduced.

Description

[0001] technical field [0002] The invention relates to the technical field of detection of a management main board, in particular to a method for online detection of a management main board. Background technique [0003] The management board is widely used in large-scale servers and rack cabinets. The management board is connected to the node mid-plane, power supply unit and fan control board, so that the power supply information of large servers and rack cabinets can be read through the management board, and server node information and Read and control fan information, and finally realize unified power supply, unified management and unified control of large servers and rack cabinets. The management board is the core of unified power supply and unified cooling for large servers and rack cabinets. At the same time, along with the sharp increase in the application of servers and rack cabinets, the number of management boards is also rapidly increasing. The number of proble...
