Embodiment 3

[0058] In one embodiment, the logic controller can also read the network card information to determine the power consumption of the network card, and then switch different power modules according to the power consumption of the network card to optimize the power supply design, thereby achieving the purpose of energy saving. optional, in figure 2 On the basis of the method described in the embodiment, as image 3 In the illustrated embodiment three, the power supply method also includes:

[0059] S104, when the logic controller detects that the power consumption of the network card is not greater than the preset power consumption threshold, disconnect the connection between the second power supply module and the network card through the logic controller; when the logic controller detects that the power consumption of the network card is greater than the preset power consumption When the consumption threshold is reached, the logic controller starts the third power supply modul...

Embodiment 5

[0068] In practical applications, when the server executes the method described in any of the above embodiments, the DC power supply DC of the server may be triggered. Therefore, in figure 2 On the basis of the method described in the embodiment, as Figure 5 In the illustrated embodiment five, the method also includes:

[0069] S107, when it is detected that the DC power supply is triggered to be powered on, start the fourth power supply module through the logic controller to provide power for the network card, start the fifth power supply module through the logic controller to provide power for peripheral devices, and turn on the power supply module through the logic controller The fuse connects the line between the fourth power source and the pluggable device.

[0070] Wherein, the fourth power supply module is a power supply that provides OCP_AUX voltage, and the OCP_AUX voltage can be obtained from the P12V_1 voltage output by the main CRPS power supply. For example, i...

Embodiment 6

[0072] In practical applications, when the server executes the method described in any of the above embodiments, the AC power supply AC of the server may be triggered. Therefore, in figure 2 On the basis of the method described in the embodiment, as Figure 6 In the illustrated embodiment six, the method also includes:

[0073] S108, when it is detected that the AC power supply is triggered to shut down, perform a shutdown operation. That is, when the server detects that the AC power supply (AC power supply) is triggered to shut down, for example, manually disconnecting the power cord of the server, the server can enter the G3 state, stop all work of the server, and perform a shutdown operation on the server.

[0074] In one embodiment, a power supply circuit of a server applying the above power supply method is also provided, such as Figure 7 In the seventh embodiment shown, the power supply circuit includes: a logic controller 10, a first power supply module 11, a first ...

Abstract

The invention relates to a power supply method and a power supply circuit of a server. According to the method, when it is detected that an alternating-current power supply is triggered to be powered on, a logic controller is initialized, a first power module is started through the logic controller to provide electric energy for working equipment in the S5 state, and when it is detected that a network card is in place, a second power module is started through the logic controller to provide electric energy for the network card, and when the logic controller detects that the network card is not in place, the connection between the second power supply module and the network card is disconnected through the logic controller. According to the method, an optimized power supply scheme for supplying power to different devices in different states is achieved, the waste phenomenon that redundant electric energy is provided for the server when the network card is not in place or the server is in the S5 state is avoided, and the method for selecting the matched power supply modules to supply power according to the power supply requirements of the devices is achieved, and the problem that the existing power supply demand and power supply capacity are unbalanced is solved.

Description

technical field [0001] The present application relates to the technical field of computer equipment, in particular to a server power supply method and circuit. Background technique [0002] With the wide application of ultra-large-scale data centers, servers have higher and higher requirements on parameters such as network bandwidth, throughput, and transmission delay. As the main accessories of servers, server network cards are used between servers, servers, and switches. connections, there are increasingly higher performance requirements. OCP 3.0 network card is a new generation of multi-functional high-performance server network card. With its advantages of high bandwidth, multiple specifications, and easy maintenance, it has gradually become the mainstream configuration server network card. [0003] At present, the OCP3.0 network card designed in the motherboard circuit of the server generally uses the AUX fan to dissipate heat, or set multiple eFUSE electronic fuses to...
