Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] In the existing fan control device, in the process of controlling the fan speed, a large number of input / output ports of the CPLD are occupied, thereby causing a waste of CPLD pin resources. The purpose of the present invention is to provide a fan control device to reduce the number of occupied CPLD input / output ports, thereby reducing the waste of CPLD pin resources. In order to enable those skilled in the art to better understand the present invention...

Abstract

The invention discloses a fan control device. The device comprises a CPLD and a multi-channel Switch chip; a BMC is connected with the input end of the CPLD and n first input ends of the multi-channelSwitch chip correspondingly, the output end of the CPLD is connected with a gating port of the multi-channel Switch chip, n second input ends of the multi-channel Switch chip are connected with a VCC, and n output ends of the multi-channel Switch chip are connected with n fans correspondingly, wherein the n is larger than or equal to 2. Obviously, according to the fan control device, only two ports of the CPLD are needed to be occupied, the rotating speed of the fans can be controlled, compared with the prior art, 2 * N +1 ports of the CPLD are required to be occupied, the occupied number ofthe CPLD ports is greatly reduced, and waste of the CPLD pin resources is avoided. Correspondingly, the invention discloses a server and the server also has the beneficial effects above.

Description

technical field [0001] The invention relates to the technical field of server communication, in particular to a fan control device and a server. Background technique [0002] With the continuous development of science and technology, servers are used more and more frequently. Since the server emits a large amount of heat in the chassis during use, whether the heat can be quickly discharged from the server is a prerequisite for the server to work stably. [0003] like figure 1 Shown is a schematic structural diagram of a fan control device in the prior art. exist figure 1 Among them, N output terminals of BMC (Baseboard Manager Controller, baseboard management controller) are connected with N input terminals of CPLD (Complex Programmable Logic Device, complex programmable logic device), and one output terminal of BMC is connected with the input terminal of CPLD, N output terminals of the CPLD are connected with N fans. exist figure 1 Among them, if the BMC is working no...
