Embodiment Construction

[0037] In order to make the description of the present invention more detailed and complete, reference may be made to the attached drawings and various embodiments described below, and the same numbers in the drawings represent the same or similar components. On the other hand, well-known components and steps have not been described in the embodiments in order not to limit the invention unnecessarily.

[0038] The embodiment of the present invention is a server with multiple main boards controlling power supply fans, which can be applied in workstations or widely used in related technical links. It is worth mentioning that this server can prevent the two motherboards from competing to control the speed of the power supply fan, thereby improving work efficiency. The following will match Figure 1 to Figure 4 To specifically describe the implementation of this server.

[0039] Please refer to figure 1 , figure 1 It is a block diagram of a server 100 with multiple motherboard...

Abstract

The invention provides a server of a power supply fan controlled by multiple mainboards for the purpose of solving the problem that two mainboards struggle to control the speed of the power supply fan. The server comprises a first mainboard, a second mainboard and a power supply backing plate, wherein the power supply backing plate is provided with a first power supply connector, a second power supply connector and a selection circuit; the first power supply connector is used for connecting the first mainboard; the second power supply connector is used for connecting the second mainboard; thefirst mainbaord provides a first selection signal when in start-up; the second mainboard provides a second selection signal when in start-up; and the selection circuit receives the first and second selection signals and selectively transmits a first power supply control signal or a second power supply control signal to the power supply backing plate so that the rotate speed of the power supply fan is controlled by the first mainbaord or the second mainboard, thereby avoiding the competition of the two mainboards.

Description

technical field [0001] The present invention relates to an electronic device, and in particular to a server with multiple main boards controlling power supply fans. Background technique [0002] In recent years, due to the development of industry and commerce and the progress of society, the relatively provided products are mainly aimed at convenience, reliability, and economic benefits. Therefore, the products currently developed are more advanced than before, and can contribute to society. [0003] In terms of servers, in recent years, the industry has continuously developed more economical and convenient power supply fans for power supply cooling, so that its operation and efficiency can achieve twice the result with half the effort. In terms of system design, the motherboard is required to control the speed of the power fan on the power supply. However, when there are two motherboards in the system, the two motherboards will compete to control the speed of the power sup...
