[0022] Optionally, the first power supply module includes an electronic fuse circuit.

[0023] According to another aspect of the present invention, a control method for an adapter card is provided for controlling the adapter card described in any embodiment of the present invention; the adapter card includes: a power interface, at least one first power supply module, a second power supply module, and at least one network card power supply interface; the input terminal of the first power supply module is electrically connected to a first power supply module of a server motherboard through the power interface, the output terminal of the first power supply module is electrically connected to the network card power supply interface, and the enable terminal of the first power supply module is connected to the controller of the server motherboard; the input terminal of the second power supply module is electrically connected to the first power supply module through the power interface, the output terminal of the second power supply module is electrically connected to the network card power supply interface, and the enable terminal of the second power supply module is connected to the controller;

[0030] The first power module is electrically connected to the input terminal of the first power supply module of the adapter card through the power interface of the adapter card.

The controller is used to output an enable signal to the first power supply module and the second power supply module after the server is connected to AC power.

[0033] The technical solution of this invention, by setting a first power supply module and a second power supply module on the adapter card, allows the server motherboard controller to send an enable signal to the first and second power supply modules before the server is powered on, if the server is connected to AC power. Upon receiving the enable signal, the first power supply module converts the first power supply voltage provided by the first power module on the server motherboard into a first supply voltage and outputs the first supply voltage to the network card power supply interface to power the network card; the second power supply module converts the first power supply voltage into a second supply voltage and outputs the second supply voltage to the network card power supply interface to power the network card.

Furthermore, the server motherboard controller can control the network card to shut down via the first and second power supply modules; therefore, it is possible to perform on / off processing of the network card in the S5 state before the server is powered on.

[0039] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0040] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0041] Figure 1 This is a schematic diagram of the structure of an adapter card provided in an embodiment of the present invention, for reference. Figure 1The adapter card 100 includes a power interface 101, at least one first power supply module 102, a second power supply module 103, and at least one network card power supply interface 104. The input terminal of the first power supply module 102 is electrically connected to the first power supply module 201 of the server motherboard 200 through the power interface 101, the output terminal of the first power supply module 102 is electrically connected to the network card power supply interface 104, and the enable terminal of the first power supply module 102 is connected to the controller 202 of the server motherboard 200. The first power supply module 102 is used to convert the first power supply voltage of the first power supply module 204 into a first power supply voltage when it receives the enable signal from the controller 202. The first power supply module 201 is connected to the first power supply module 201 via a power interface 101, and the output of the second power supply module 103 is connected to the network card power supply interface 104. The enable terminal of the second power supply module 103 is connected to the controller 202. The second power supply module 103 is used to convert the first power supply voltage into a second power supply voltage when it receives the enable signal from the controller 202, and output the second power supply voltage to the network card power supply interface 104 to power the server's network card before the server is powered on.

[0042] The adapter card 100, for example, is a Riser adapter card, a PCIe adapter or expansion card used to add slots, facilitating the connection of more devices, such as network cards, graphics cards, or sound cards, to the server motherboard 200. The first power supply module 102 may include a boost circuit or a buck circuit, a fuse circuit, or other voltage conversion circuits. The first power supply module 102 converts the first power supply voltage provided by the first power module 201 into a first supply voltage, such as the main power supply voltage required by the network card, i.e., the power supply voltage required by the main control chip on the network card. The second power supply module 103 may include a boost circuit or a buck circuit, or other voltage conversion circuits. The second power supply module 103 converts the first power supply voltage provided by the first power module 201 into a second supply voltage, such as powering the memory or optical port on the network card. The network card power supply interface 104 is provided with at least two sub-interfaces. Different sub-interfaces can output different power supply voltages, so different power supply voltages (first power supply voltage and second power supply voltage) can be output to the network card to power different devices on the network card and meet the power supply requirements of different devices.

[0043] Specifically, when the server is powered off, if the server is connected to AC power, the server will enter the S5 state, at which time the server is not powered on. In the S5 state, the first power module 201 on the server motherboard 200 can provide a first power supply voltage, such as 12V_STBY voltage. When the first power supply module 102 receives the enable signal from the controller 202, the first power supply module 102 will convert the first power supply voltage 12V_STBY into a first supply voltage, such as 12V voltage, but it can also be a voltage of other values. The first power supply module 102 outputs the first supply voltage to the load, such as the network card or graphics card, through the network card power supply interface 104. Thus, before the server is powered on, that is, when the server is in the S5 state, power is supplied to the server's network card or graphics card. When the second power supply module 103 receives the enable signal from the controller 202, it converts the first power supply voltage 12V_STBY into a second power supply voltage, such as 3.3V, or other values. The second power supply module 103 outputs the second power supply voltage to the load, such as a network card or graphics card, through the network card power supply interface 104. Thus, before the server is powered on, i.e. when the server is in S5 state, power is supplied to the server's network card or graphics card. Therefore, when the server is in S5 state, the power consumption requirements of the network card or graphics card can be met, and the server's network card or graphics card can operate normally.

[0044] Furthermore, the controller 202, for example, is a Baseboard Management Controller (BMC), which performs operations such as firmware upgrades and monitoring of the server when it is not powered on. When the server is in state S5, the first power supply module 102 and the second power supply module 103 will only supply power to the network card when they receive the enable signal from the controller 202, enabling the network card to operate. When the first power supply module 102 and the second power supply module 103 receive the power off signal from the controller 202, they will stop outputting the first and second power supply voltages, causing the network card to power off. Thus, the power off of the network card can be controlled by the first power supply module 102 and the second power supply module 103. The controller 202 can also control the network card to power off independently. Therefore, it is possible to turn the network card on and off in state S5.

[0045] It should be noted that, Figure 1 This illustration only shows the case where the adapter card has two first power supply modules 102 and two network card power supply interfaces 104, but it is not a limitation. The specific number of network card power supply interfaces 104 can be determined according to the actual number of network cards that need to be connected.

[0046] The technical solution of this embodiment, by setting a first power supply module and a second power supply module on the adapter card, allows the server motherboard controller to send an enable signal to the first and second power supply modules before the server is powered on, if the server is connected to AC power. Upon receiving the enable signal, the first power supply module converts the first power supply voltage provided by the first power module on the server motherboard into a first supply voltage and outputs the first supply voltage to the network card power supply interface to power the network card; the second power supply module converts the first power supply voltage into a second supply voltage and outputs the second supply voltage to the network card power supply interface to power the network card. Thus, power is supplied to the server's network card or graphics card before the server is powered on, ensuring the server's network card or graphics card can operate normally before power-on. Furthermore, the server motherboard controller can control the network card to shut down via the first and second power supply modules; therefore, it is possible to perform on / off processing of the network card in the S5 state before the server is powered on. The technical solution of this embodiment solves the problem that when the adapter card is connected to a device that cannot be powered independently, the device cannot operate normally in the S5 state before the server is powered on; it realizes powering the server's network card or graphics card before the server is powered on, and realizes the on / off processing of the network card in the S5 state before the server is powered on.

[0047] Figure 2 This is a schematic diagram of another adapter card provided in an embodiment of the present invention. Optionally, refer to... Figure 2 The adapter card 100 also includes an input / output expansion module 105; the input terminal of the input / output expansion module 105 is connected to the controller 202, the output terminal of the input / output expansion module 105 is electrically connected to the enable terminal of the first power supply module 102, and the output terminal of the input / output expansion module 105 is also electrically connected to the enable terminal of the second power supply module 103; the input / output expansion module 105 is used to convert the control signal of the controller 202 into an enable signal, and output the enable signal to the first power supply module 102 and the second power supply module 103.

[0048] Specifically, the input / output expansion module 105 includes, for example, an input / output (I / O) expander. The I / O expansion module 105 can communicate with the controller 202, for example, via serial communication. The I / O expansion module 105 receives control signals sent by the controller and converts these control signals into enable signals. When the controller 202 detects that the server is connected to AC power, the controller 202 outputs an enable control signal to the I / O expansion module 105. The I / O expansion module 105 converts the control signal into an enable signal. After receiving the enable signal, the first power supply module 102 and the second power supply module 103 output a first power supply voltage to the network card power supply interface 104, and the second power supply module 103 outputs a second power supply voltage to the network card power supply interface 104, thereby powering the network card or graphics card. This ensures that the network card can operate normally in the S5 state before the server is powered on.

[0049] Optionally, refer to Figure 2 The adapter card 100 also includes a controller interface 106; the input terminal of the input / output expansion module 105 is connected to the controller 202 through the controller interface 106; the power terminal of the input / output expansion module 105 is electrically connected to the second power module 203 of the server motherboard 200 through the controller interface 106. The controller interface 106 is used to output the second power supply voltage of the second power module 203 to the power terminal of the input / output expansion module 105 so as to supply power to the input / output expansion module 105 before the server is powered on.

[0050] Specifically, the input / output expansion module 105 can obtain the control signal output by the controller 202 through the controller interface 106, and can obtain the second power supply voltage provided by the second power module 203 through the controller interface 106. The second power supply voltage is, for example, 3.3V_STBY, so that the input / output expansion module 105 can operate normally before the server is powered on.

[0051] Optionally, refer to Figure 2 The adapter card 100 also includes a temperature detection module 107; the temperature detection module 107 is connected to the controller 202 through the controller interface 106, and the temperature detection module 107 is used to detect the temperature information of the adapter card and send the temperature information to the controller 202; the power supply terminal of the temperature detection module 107 is electrically connected to the second power supply module 203 through the controller interface 106, and the controller interface 106 is used to output the second power supply voltage to the power supply terminal of the temperature detection module 107 so as to supply power to the temperature detection module 107 before the server is powered on.

[0052] Specifically, the temperature detection module 107, including a temperature sensor, can detect the temperature information of the adapter card and send it to the controller 202 via the controller interface 106. This allows the controller 202 to monitor the temperature status of the adapter card in real time and take timely measures, such as controlling the operation of the cooling fan, when the temperature of the adapter card is too high. Furthermore, the temperature detection module 107 can obtain the second power supply voltage provided by the second power module 203 through the controller interface 106, ensuring that the temperature detection module 107 can operate normally in the S5 state before the server is powered on.

[0053] Optionally, refer to Figure 2 The adapter card 100 also includes a storage module 108; the storage module 108 is connected to the controller 202 through the controller interface 106, and the storage module 108 is used to store the configuration information of the adapter card; the power supply terminal of the storage module 108 is electrically connected to the second power module 203 through the controller interface 106, and the controller interface 106 is used to output the second power supply voltage to the power supply terminal of the storage module 108 so as to supply power to the storage module 108 before the server is powered on.

[0054] Specifically, the storage module 108 includes, for example, a memory, such as a programmable memory. The storage module 108 can obtain configuration information of the adapter card 100 sent by the controller 202 through the controller interface 106, including information such as the serial number of the adapter card 100. Furthermore, the storage module 108 can obtain the second power supply voltage provided by the second power module 203 through the controller interface 106, enabling the storage module 108 to operate normally in the S5 state before the server is powered on.

[0055] In addition, the temperature detection module 107 and the storage module 108 have their own address information, and the controller 202 can communicate with the corresponding temperature detection module 107 or storage module 108 according to the address information.

[0056] Optionally, refer to Figure 2 The adapter card 100 also includes a first bandwidth adjustment module 109 and a second bandwidth adjustment module 110; the output end of the first power supply module 102 is electrically connected to the network card power supply interface 104 through the first bandwidth adjustment module 109; the output end of the second power supply module 103 is electrically connected to the network card power supply interface 104 through the second bandwidth adjustment module 110.

[0057] Specifically, the first bandwidth adjustment module 109 includes, for example, a Slimline connector, and the second bandwidth adjustment module includes, for example, a Slimline connector. The Slimline connector can adjust the bandwidth to adjust the output bandwidth of the first power supply module 102 and the second power supply module 103, so that the network card power supply interface 104 matches the network card, thereby ensuring that the bandwidth of the output first power supply voltage and the second power supply voltage meets the requirements of the network card.

[0058] Optionally, refer to Figure 2 The first power supply module 102 includes an electronic fuse circuit.

[0059] Specifically, the first power supply module 102 includes an electronic fuse circuit, which integrates overcurrent, overheat and overvoltage protection functions. When the first power supply voltage output by the first power supply module 102 is too large or the current corresponding to the first power supply voltage is too large, protective measures are taken to achieve the effect of protecting the circuit and the adapter board.

[0060] For example, since the first power supply voltage and its corresponding current are relatively large, a corresponding first power supply module 102 is set for each network card power supply interface 104. That is, the number of first power supply modules 102 is the same as the number of network card power supply interfaces 104, which helps to ensure the stable operation of the circuit and thus ensure the normal operation of the network card.

[0061] It should be noted that, Figure 2 This illustration only shows the case where the adapter card has two first power supply modules 102 and two network card power supply interfaces 104, but it is not a limitation. The specific number of network card power supply interfaces 104 can be determined according to the actual number of network cards that need to be connected.

[0062] Figure 3 This is a flowchart of a control method for an adapter card provided in an embodiment of the present invention, see reference. Figure 1 and Figure 3 The control method for the adapter card is used to control the adapter card in any embodiment of the present invention; the control method is executed by a controller on the server motherboard; the control method includes:

[0063] S301. After the server is connected to AC power, an enable signal is output to the first power supply module and the second power supply module; so that the first power supply module outputs the first power supply voltage to the network card power supply interface, and the second power supply module outputs the second power supply voltage to the network card power supply interface, thereby powering the server's network card before the server is powered on.

[0064] Specifically, the control method of the adapter card is executed by the controller 202 on the server motherboard 200, such as the baseboard management controller. After the server is connected to AC power, that is, after the server's power supply unit (PSU) is connected to AC power, the controller 202 will know that the server is connected to AC power, that is, it will know that the server has entered the S5 state. The controller 202 will output an enable signal to the first power supply module 102. The first power supply module 102 will convert the first power supply voltage 12V_STBY into a first supply voltage, such as 12V, but it can also be other values. The first power supply module 102 outputs the first supply voltage to the load, such as the network card or graphics card, through the network card power supply interface 104. Thus, before the server is powered on, that is, when the server is in the S5 state, power is supplied to the server's network card or graphics card. When the second power supply module 103 receives the enable signal from the controller 202, it converts the first power supply voltage 12V_STBY into a second power supply voltage, such as 3.3V, or other values. The second power supply module 103 outputs the second power supply voltage to the load, such as the network card or graphics card, through the network card power supply interface 104. Thus, before the server is powered on, i.e. when the server is in S5 state, it supplies power to the server's network card or graphics card. Therefore, when the server is in S5 state, the server's network card or graphics card can operate normally.

[0065] Based on the above technical solution, optionally, the control method of the adapter card also includes:

[0066] Output a shutdown signal to the first power supply module and the second power supply module to control the network card to shut down.

[0067] For example, refer to Figure 1 When the network card is not needed, the controller 202 of the server motherboard sends a shutdown signal to the first power supply module 102 and the second power supply module 103. When the first power supply module 102 and the second power supply module 103 receive the shutdown signal from the controller 202, they stop outputting the first power supply voltage and the second power supply voltage, thereby shutting down the network card. Thus, the network card can be shut down by controlling the first power supply module 102 and the second power supply module 103. The controller 202 can also control the network card to shut down independently. Therefore, it is possible to turn the network card on and off in the S5 state before the server is powered on.

[0068] This invention also provides a server, which includes an adapter card 100 according to any embodiment of the invention, and a server motherboard 200. The server motherboard 200 includes a first power module 201 and a controller 202. The first power module 201 is electrically connected to the input terminal of the first power supply module 102 of the adapter card 100 through the power interface 101 of the adapter card 100. The first power module 201 is used to provide a first power voltage to the first power supply module 102 before the server is powered on. The first power module 201 is also electrically connected to the input terminal of the second power supply module 103 of the adapter card 100 through the power interface 101. The first power module 201 is used to provide a first power voltage to the second power supply module 103 before the server is powered on. The controller 202 is electrically connected to the enable terminal of the first power supply module 102 and the second power supply module 103. The controller 202 is used to output an enable signal to the first power supply module 102 and the second power supply module 103 after the server is connected to AC power.

[0069] The server provided in this embodiment includes the adapter card provided in any of the above implementation schemes. The implementation principle and technical effect of the server provided in this embodiment are similar to those of the above implementation schemes, and will not be repeated here.

For example, the steps described in this invention can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution of this invention can be achieved, and this is not limited herein.

[0071] The specific embodiments described above do not constitute a limitation on the scope of protection of this invention.
