Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] The invention provides a method for the server fan to rotate at full speed after the BMC fails. The invention determines whether the BMC is in the failure state by monitoring the periodic pulse signal sent by the BMC in the normal working state. Through the determined state, the signal gating of the gating line is realized, so that the fan can still work according to the normal fan control signal after the BMC fails, and the normal heat dissipation function of the system is guaranteed.

[0016] as attached figure 1 As shown, the specific implementation process is:

[0017] Inside the server, the BMC is used as the controller of the fan speed, and the BMC outputs periodic pulse signals as the dog feeding signal under normal working conditions, and the BMC chip is connected to the single-chip microcomputer, which is used as the monitoring...

Abstract

This invention discloses a method for rotating a fan of a server at full-speed after BMC (Baseboard Management Controller) fails. The method specifically comprises the following steps: the BMC is used as a controller of the rotating speed of the fan in the server; periodic pulse signals are output as feeding-dog signals when the BMC works normally, and a chip of the BMC is connected with a single chip; the single chip is used as a monitoring unit of the working state of the BMC; through monitoring the feeding-dog signals sent out by the BMC, the single chip monitors whether the BMC works normally or not; and after the BMC fails, the rotating speed of the fan is regulated to ensure normal heat dissipation of the system. Compared with the prior art, the method for rotating the fan of the server at full-speed after the BMC fails monitors the working state of the BMC; through detecting the working state of the MBC, when the failure of the BMC and the abnormal working situation are found, a gating line gates high-level signals to control the rotating speed of the fan; thus, the server can work normally; the method has strong practicality, and is easy to popularize.

Description

technical field [0001] The invention relates to the technical field of computer servers, in particular to a method with strong practicability and full-speed rotation of the fan of the server after the BMC fails. Background technique [0002] With the rapid development of technology, people have higher and higher requirements for the ease of use, flexibility, versatility, stability and power consumption of products. [0003] In the current server design, BMC chips are generally used to manage the motherboard. The BMC can detect and control power consumption, temperature, and fan speed to achieve better management of the motherboard. In current server applications, people have higher and higher requirements for servers in terms of power consumption and stability. However, the BMC chip solution will have a certain failure rate. When the BMC chip fails, the fan loses control. Therefore, the normal operation of the server system cannot be guaranteed, thereby causing the overall...
