Abstract

The invention provides a method and a device for remotely testing the stability of a server PWM fan. The method comprises the following steps that S1, a to-be-tested server PWM fan test network environment is configured, and a PWM fan interface is controlled through a fan control terminal and a to-be-tested server BMC to carry out stability testing; S2, the fan control terminal simulates on-off ofa PWM fan power supply signal through the PWM fan interface, and then whether control of the PWM fan interface on the fan power supply state is effective or not is verified through a wind speed sensor and the to-be-tested server BMC; S3, the fan control terminal simulates on-off of a PWM fan speed regulation signal through the PWM fan interface, and whether the PWM fan can normally regulate the speed or not is verified through the to-be-tested server BMC and a fan sensor; and S4, the fan control terminal simulates on-off of a PWM fan wind speed feedback signal through the PWM fan interface, and whether the PWM fan can normally feed back the wind speed or not is verified through the to-be-tested server BMC.

Description

technical field [0001] The invention belongs to the technical field of server fan testing, and in particular relates to a method and a device for remotely testing the stability of a PWM fan of a server. Background technique [0002] With the rapid development of all walks of life, the demand for servers is increasing, and more and more customers use a large number of servers as core applications. Today's servers run 7*24 hours without any special circumstances; most servers use PWM fans for air cooling and heat dissipation; and the internal temperature of the server directly determines the work of various components of the server such as CPU, memory, etc. Stability; therefore PWM fan stability is one of the most important criteria to measure the stability of the server. [0003] At present, manual methods are generally used to test the PWM fans of servers; for example, manually plugging and unplugging fans on site, blocking fan blades to simulate fan failures, etc., and the...
