Problems solved by technology

[0003] The traditional method of testing the speed regulation function of the system fan requires the use of system tools to change the temperature of the CPU and memory. However, the system tool has limitations and cannot make the temperature of the CPU and memory too high or low, so it cannot meet the requirements of testing the low speed and temperature of the system fan. full speed demand

Embodiment Construction

[0008] A method for testing the system fan speed regulation function of the present invention, the test method is that OEM IPMI commands in the BMC, the test user uses the IPMITool software to send the IPMI commands under Dos, and informs the BMC that the system fan speed is set to a specific value. level, and then read all fan speeds to determine whether it is at a specific speed level. Firstly, format the U disk into a Dos boot disk under the windows system; secondly, copy the IPMITool software under Dos to the U disk; thirdly, start the system into Dos, use the IPMITool software to send specific IPMI commands to the BMC, and the BMC will follow this The IPMI command controls the fan speed to be at a specific speed level; finally, use the IPMITool software to send the IPMI command to read the speed of all fans, and determine whether the speed of all fans is at a specific speed level.

Abstract

The invention provides a method for testing the speed-adjusting function of a system fan, wherein the IPMI (Intelligent Platform Management Interface) instructions of an OEM (original equipment manufacturer) are sent to a BMC (Baseboard Management Controller); according to the IPMI instructions, the BMC controls the system fan in four grades, such as a low speed, an intermediate speed, a high speed and a full speed, then checks the rotation speed of the fan, and determines whether the rotation speed of the fan is in a specific rotation speed grade; therefore, the purpose of testing and verifying the correctness of the speed-adjusting function of the fan is achieved; and the method comprises the following specific steps: (1) formatting a U flash disk into a Dos startup disk under a windows system; (2) copying IPMIToo1 software under Dos into the U flash disk; (3) starting a system to enter the Dos, sending specific IPMI instructions to the BMC by using the IPMIToo1 software, and controlling the rotation speed of the fan to be in a specific rotation speed grade according to the IPMI instructions by the BMC; and (4) sending the IPMI instructions to read all rotation speeds of the fan by using the IPMIToo1 software, and judging whether all the rotation speeds of the fan are below the specific rotation speed grade.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method for testing the speed regulation function of a system fan. Background technique [0002] In the development of high-performance servers, system fans play an important role. The system fan is used to meet the heat dissipation requirements of high-performance servers and ensure that all components can work normally and stably. While meeting heat dissipation requirements, low power consumption and low noise have become the goals pursued by all manufacturers. Therefore, using BMC to realize fan speed regulation function has become a must-have function. However, when testing and verifying this function, the traditional method is to use system tools to change the system CPU and memory temperature, trigger the BMC to change the condition of the system fan speed, and test and verify the correctness of the fan speed regulation function. [0003] The traditional method of testing the sp...
