Problems solved by technology

In order to make the fan operate effectively in the existing electronic product system, the fan tachometer (FAN CONTROL TABLE) is generally updated in time according to the operating status of the electronic product system. The update of the fan tachometer in the existing electronic product system is related to the board management in the electronic product system. The controller firmware (BMC firmware) is independent of each other. In the process of updating the fan tachometer, if a power failure occurs, the fan tachometer will lose its function or produce wrong speed control

Embodiment Construction

[0009] The technical content of the present invention is described below through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific examples, and various modifications and changes can be made to the details in this specification based on different viewpoints and applications without departing from the spirit of the present invention.

[0010] Such as figure 1 Shown is a method for updating a fan tachometer according to the present invention. The method is applied in an electronic product system having a baseboard management controller. A preset fan tachometer is stored in the baseboard management controller. The preset fan tachometer is, for example, is a data file (dat file), and the electronic product system is, for example, a server system. The method for updating...

Abstract

A fan tachometer update method is applied in an electronic product system with a baseboard management controller (BMC), and the baseboard management controller stores a preset fan tachometer, so that the baseboard management controller receives the input update the fan speed data and store the updated data in a temporary storage space, then write the data stored in the temporary storage space into a temporary fan speed table, and check whether the temporary fan speed table is consistent with the input fan speed update data , as a judgment of data integrity, if yes, the temporary fan speed table will overwrite the preset fan speed table, and the temporary fan speed table can be deleted.

Description

technical field [0001] The invention relates to a fan tachometer updating technology, in particular to a fan tachometer updating technology applied in an electronic product system with a base board management controller. Background technique [0002] With the vigorous development of the electronic industry, electronic products have gradually entered the direction of multi-functional and high-performance research and development. In order to meet the miniaturization packaging requirements of electronic products, the heat generated by the electronic components on the circuit board of electronic products will increase significantly, and the demand for the number of fans will also increase relatively. For example, the existing 1U or 2U electronic product systems are all Equipped with 6 to 8 fans, or even as many as 12 fans, the existing electronic product system can dynamically adjust the fan speed according to its operating status so as to transfer the heat generated by the ope...
