Fan board control method, system and equipment and medium

Abstract

The invention discloses a fan board control method. The fan board control method comprises the following steps that each connector is used for receiving actual installation position data sent by the corresponding connected fan board; according to the actual installation position data, whether the actual installation position of the fan board connected with the connector is a preset installation position or not is judged; and in response to the fact that the actual installation position of the fan board connected with the connector is not the preset installation position, the sequence of the fan board control signals sent to the connector is adjusted through control signals generated according to the actual installation position data. The invention further discloses a system, computer equipment and a readable storage medium. According to the method, fool-proof design of the fan board is achieved by collecting the position information of the fan board, normal sorting control of the fans can be achieved even if the cables are assembled and inserted reversely, and usability and maintainability of products are improved.

Description

technical field [0001] The present invention relates to the field of servers, in particular to a control method, system, equipment and storage medium for a fan board. Background technique [0002] Such as figure 1 As shown, the two fan boards in a 4U node usually use the same model, and there is no difference in hardware and structure. There are usually two identical connectors on the Host board to connect the two boards, and each connector is connected to the The actual installation position of the fan board needs to correspond to the preset position, that is, the fan board connected to connector 1 needs to be placed on the upper layer, and the fan board connected to connector 2 needs to be placed on the lower layer. [0003] Such as figure 2 As shown, when numbering the fans on the fan board, the method is generally from top to bottom and from left to right. Controllers are unaware. In this way, when the fan board 2 connected to the connector 1 is on the lower layer a...

Problems solved by technology

[0003] like figure 2 As shown, when numbering the fans on the fan board, the method is generally from top to bottom and from left to right. The controller is unaware

In this way, when the fan board 2 connected to the connector 1 is on the lower layer and the fan board 1 connected to the connector 2 is on the upper layer, the order of the fans corresponding to the in-position signal and the speed signal fed back by the connector to the upper layer is reversed, that is, the connector 1 The feedback to the upper-layer controller is actually the fan presence signal and speed signal of fan board 2 (that is, the fan presence signal and speed signal numbered 5-9), but the upper-layer controller still thinks it is received from connector 1 by default. The received fan in-position signal and speed signal are those of the fans numbered 0-4, which will cause the fan number corresponding to the alarm given by the upper controller when the fan on fan board 2 fails It is different from the number on the server label. For example, when the fan numbered 5 on fan board 2 fails, the BMC will give the fan numbered 1 a fault. separate control

[0004] Therefore, when the server is assembled, it is usually distinguished by the cable label or from the selection of the HOST-side connector. The assembler needs to carefully check the connection of the cables. However, because the fan board models are the same, the fan board-side connectors cannot be distinguished. It is very easy to reverse the cable insertion, which will affect product maintenance and ease of use
