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 preventing overheating of a server system after a BMC fails. The invention determines whether the BMC is in a failure state by monitoring the periodic pulse signal sent by the BMC in a normal working state. Through the determined state, the signal gating of the gating line is realized to ensure that the fan can still work according to the fan control signal generated by the pulse generator after the BMC fails, so as to ensure the normal cooling function of the system.

[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...

Abstract

The invention discloses a method for preventing overheating of a server system after a BMC fails. The specific implementation process is as follows: inside the server, the BMC is used as the controller of the fan speed, and the BMC outputs a periodic pulse signal as a feeder in a normal working state. The dog signal connects the BMC chip to the single-chip microcomputer. The single-chip microcomputer is used as the monitoring unit of the BMC working state. By monitoring the dog feeding signal thrown by the BMC, it can monitor whether the BMC is working normally. When the BMC fails, the fan speed can be adjusted to ensure the system. Normal cooling. Compared with the prior art, this method for preventing the overheating of the server system after the BMC fails realizes the monitoring of the working state of the BMC. By detecting the working state of the MBC, when it is found that the BMC fails to work abnormally, the strobe line strobe pulse generator generates The signal realizes the control of the rotational speed of the fan, ensures that the server can work normally, has strong practicability, 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 preventing overheating of a server system after BMC failure. 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 powe...
