[0002] With the large-scale deployment of 5G edge computing or high-energy consumption of artificial intelligence (AI) system servers, computer servers are often distributed in remote areas, and traditional on-site maintenance mode faces high cost challenges. The auxiliary power supply of the current server is directly connected to the external power supply, even if the main system power supply is remotely controlled to be turned off, the auxiliary power supply of the key components of the central processing module still maintains power supply, so that the key components are in a low-power running state. This not only limits the depth of operation demand in the remote maintenance scene, but also leads to energy waste and accelerated hardware aging. Therefore, there is room for improvement.

[0021] In the following description, a large number of details are discussed to provide a more thorough explanation of the embodiments of the present application. However, it is obvious to those skilled in the art that the embodiments of the present application can be implemented without these specific details, and in other embodiments, well-known structures and devices are shown in block diagrams rather than in detail to avoid making the embodiments of the present application difficult to understand.

[0022] Referring to Figure 1 The present application provides a power supply system of a server, which can receive control instructions sent by remote personnel to power on, power off or reset the central processing module 50 of the server. The control instructions can include power-on instructions, power-off instructions, and reset instructions. The power supply system can include a power module 10, a baseboard management control module 20, a switch module 30, and a reset module 40. The server of the present application can be applied to, for example, a network platform server (such as a 5G network server), a data center (such as a large-scale cloud data center), a database (such as a financial database server), an AI computing server (such as an edge computing platform server), a server of a monitoring and data acquisition system, a traffic control system server, an intelligent power grid platform server, a distributed control system (DCS) operation station, an artificial intelligence and high-performance computing (HPC) server, a big data analysis server, a network security platform server, a communication and collaboration platform server, or other suitable types of servers.

[0023] Referring toFigure 1 In some embodiments, the power supply unit 10 (PSU) can be connected to an external power source (e.g. a power grid or a battery) through an external power line, and convert the input power (e.g. AC or DC) into a stable power supply required by the server to power the server. The power supply unit 10 can also be used to output another 12V power supply (P12V_PSU) to power other modules inside the server.

[0024] Referring to Figure 1 , Figure 2 and Figure 3 In some embodiments, the baseboard management control module 20 can be electrically connected between the power supply unit 10 and the central processing module 50 of the server, for generating corresponding power-on signals, power-off signals, and reset signals according to external power-on instructions, power-off instructions, and reset instructions, respectively. The baseboard management control module 20 can include a first voltage conversion unit 21, a baseboard management control unit 22, a signal output unit 23, a first MOS transistor M1, a first resistor R1, and a first capacitor C1.

[0025] Referring to Figure 3 In some embodiments, the first voltage conversion unit 21 can be, for example, a DC-DC (Direct Current-Direct Current) converter, which can be used to adjust the voltage of the power supply provided by the power supply unit 10, and convert the voltage output by the power supply unit 10 into a specific voltage required by other devices (e.g. the baseboard management control unit 22, the signal output unit 23, etc.). For example, the voltage of the power supply provided by the power supply unit 10 can be 12V, and the first voltage conversion unit 21 can receive the 12V power supply and convert it into different power supplies according to the requirements, such as 1.5V, 1.2V, 2.5V, etc. The converted power supply can be provided to the baseboard management control unit 22, the signal output unit 23, etc. to meet the power supply requirements of these units.

[0026] Referring to Figure 3In some embodiments, the baseboard management control unit 22 may, for example, be a baseboard management controller (BMC) or an embedded management controller, which can be used to monitor and manage the status of the hardware device, and perform remote control operations. The baseboard management control unit 22 can receive control instructions sent by remote personnel through a communication module (such as a network interface, serial port, etc.), and perform corresponding operations according to the instructions. The control instructions can include power-on instructions, power-off instructions, and reset instructions. Remote personnel can send power-on instructions to require the baseboard management control unit 22 to power on the device. Remote personnel can send power-off instructions to require the baseboard management control unit 22 to cut off the power supply of the device. Remote personnel can send reset instructions to require the baseboard management control unit 22 to reset the device.

[0027] Referring to Figure 3 In some embodiments, the signal output unit 23 may, for example, be an I / O expansion chip, which is used to receive control signals and generate corresponding output signals. For example, the signal output unit 23 can generate corresponding power-on signals, power-off signals, and reset signals according to power-on instructions, power-off instructions, and reset instructions. Specifically, when it is required to power on the central processing module 50, the signal output unit 23 generates a power-on signal, which can be represented as an AUX_ON signal being 1. When it is required to cut off the power supply of the central processing module 50, the signal output unit 23 generates a power-off signal, which can be represented as an AUX_ON signal being 0. When it is required to reset the central processing module 50, the signal output unit 23 generates a reset signal, which can be represented as an RTCRSTn signal being 1. AUX_ON is a GPIO (general-purpose input / output) signal sent by the BMC, which is used to control the switch module.

[0028] Referring to Figure 3In some embodiments, one end of the first capacitor CI is electrically connected to the output end of the power module 10, directly receiving the power supply output by the power module 10. The other end of the first capacitor CI is grounded (GND), forming a current loop. The first capacitor CI can filter the power supply output by the power module 10. By filtering, the noise, ripple and other interference signals in the power supply are eliminated or reduced, ensuring the stability and purity of the power supply. Specifically, the first capacitor CI has energy storage characteristics. When the voltage output by the power module 10 fluctuates, the first capacitor CI can absorb or release electrical energy, thereby smoothing the voltage fluctuations. The first capacitor CI has a low impedance characteristic for high-frequency noise, which can short-circuit the high-frequency noise to the ground, thereby filtering out high-frequency interference in the power supply. For low-frequency ripple, the first capacitor CI reduces the voltage fluctuation amplitude through charging and discharging, making the power supply more stable. After filtering the power supply, the filtered power supply can be provided to the second voltage conversion unit 31 and the first MOS tube Ml. The size of the first capacitor CI can not be limited, for example, it can be 5-15 μF.

[0029] Please refer to Figure 3 In some embodiments, the first MOS tube Ml is an N-MOS transistor (for example, using model NX7002), which is turned on when the gate is low and turned off when the gate is high. The gate (Gate) of the first MOS tube Ml can be electrically connected to the output end of the signal output unit 23 for receiving the power-on signal or the power-off signal. The source (Source) of the first MOS tube Ml can be electrically connected to the power module 10 through the first resistor Rl for receiving the 12V power supply provided by the power module 10 and filtered. The source of the first MOS tube Ml can also be electrically connected to the switch module 30. The drain (Drain) of the first MOS tube Ml can be grounded (GND) as a current loop. Among them, the first resistor Rl can function as a voltage reducer to supply power to the first MOS tube Ml after reducing the 12V power supply. The size of the first resistor Rl can not be limited, for example, it can be 5-15 KΩ.

[0030] In some embodiments, when the signal output unit 23 outputs the power-on signal (for example, the AUX_ON signal is 1), the first MOS tube Ml enters the on state, and in the on state, the source of the first MOS tube Ml can output the first conduction signal to the switch module 30. When the signal output unit 23 outputs the power-off signal (for example, the AUX_ON signal is 0), the first MOS tube Ml enters the off state, and in the off state, the source of the first MOS tube Ml cannot output the first conduction signal to the switch module 30. At this time, the switching state of the switch module 30 can be controlled by the different states of the first MOS tube Ml, thereby controlling the power supply of the central processing module 50.

[0031] Referring to Figure 1 and Figure 3 In some embodiments, the switch module 30 can be electrically connected between the power module 10 and the central processing module 50. The switch module 30 can be used to enter the on state according to the power-on signal to supply power to the central processing module 50. The switch module 30 is also used to enter the off state according to the power-off signal to stop supplying power to the central processing module 50. The switch module 30 can include a second voltage conversion unit 31, a second capacitor C2, and a second MOS tube M2.

[0032] Referring to Figure 3 In some embodiments, the second MOS tube M2 can be a P-MOS transistor (for example, IRF9310). The gate of the second MOS tube M2 can be electrically connected to the source of the first MOS tube M1 for receiving the first conduction signal. The source of the second MOS tube M2 can be electrically connected to the power module 10 for receiving the power supply provided by the power module 10. The drain of the second MOS tube M2 can be electrically connected to the central processing module 50 for outputting the power supply to the central processing module 50. When the first MOS tube M1 enters the on state and generates the first conduction signal, the second MOS tube M2 enters the on state when receiving the first conduction signal. When the first MOS tube M1 enters the off state, the second MOS tube M2 also enters the off state. The second MOS tube M2 passes or blocks the power supply of the power module 10 through the on or off state, thereby controlling the working state of the central processing module 50. The second MOS tube M2 functions as a switch in the circuit and controls the on-off of the power supply according to the first conduction signal.

[0033] Referring to Figure 3 In some embodiments, one end of the second capacitor C2 is electrically connected to the drain of the second MOS tube M2, and the other end of the second capacitor C2 is grounded (GND), forming a current loop. The second capacitor C2 can filter the power supply output by the second MOS tube M2. Through filtering, interference signals such as noise and ripple in the power supply are eliminated or reduced, ensuring the stability and purity of the power supply. The size of the second capacitor C2 can not be limited, for example, it can be 5-15 μF.

[0034] Referring to Figure 3 In some embodiments, the second voltage conversion unit 31 can be a DC-DC (direct current-direct current) converter, which can be used to adjust the voltage of the filtered power supply provided by the second MOS tube M2, and convert the voltage output by the second MOS tube M2 into a specific voltage required by the central processing module 50 and its internal key components.

[0035] Referring to Figure 1 and Figure 3In some embodiments, the reset module 40 can be electrically connected between the signal output unit 23 and the central processing module 50. The reset module 40 can be used to enter the conduction state according to the reset signal to clear the data stored in the central processing module 50. The reset module 40 can include a third capacitor C3, a second resistor R2, a third resistor R3, a third MOS tube M3, and a fourth MOS tube M4.

[0036] Referring to Figure 3 In some embodiments, the substrate management control unit 22 can be provided with a power supply end. The power supply end can output a power supply to supply power to the third MOS tube M3 and the fourth MOS tube M4. The power supply can be a 3.3V direct current power supply, which can be represented as BMC_P3V3_SB. One end of the third capacitor C3 is electrically connected to the power supply end of the substrate management control unit 22, and the other end of the third capacitor C3 is grounded (GND) to form a current loop. The third capacitor C3 can filter the power supply output by the power supply end. The size of the third capacitor C3 can not be limited, for example, it can be 5-15μF.

[0037] Referring to Figure 3 In some embodiments, the third MOS tube M3 can be an N-MOS transistor (for example, NX7002). When the gate is low, the third MOS tube M3 is turned on, and when the gate is high, the third MOS tube M3 is turned off. The gate (Gate) of the third MOS tube M3 can be electrically connected to the output end of the signal output unit 23 to receive the reset signal. The source (Source) of the third MOS tube M3 can be electrically connected to the power supply end of the substrate management control unit 22 through the second resistor R2 to receive the power supply provided by the substrate management control unit 22. The drain (Drain) of the third MOS tube M3 can be grounded (GND) as a current loop. The second resistor R2 can be used to step down the preset voltage (for example, 3-5V) power supply and supply power to the third MOS tube M3 through the stepped-down power supply. The size of the second resistor R2 can not be limited, for example, it can be 5-15KΩ.

[0038] Referring to Figure 3In some embodiments, when the signal output unit 23 outputs a reset signal (e.g., the RTCRSTn signal is 1), the third MOS transistor M3 enters an on state, in which the source of the third MOS transistor M3 can output a second enable signal to the fourth MOS transistor M4. When the signal output unit 23 does not output a reset signal (e.g., the RTCRSTn signal is 0), the third MOS transistor M3 enters an off state, in which the source of the third MOS transistor M3 cannot output a second enable signal to the fourth MOS transistor M4. The RTCRSTn signal can be a low-active signal sent to the central processing module 50. When the central processing module 50 detects that the signal is pulled low and remains for a certain period of time, it will clear the CMOS settings stored in its internal RAM, such as BIOS configuration, hardware boot sequence, security key, etc., and restore them to the factory default values.

[0039] Referring to Figure 3 In some embodiments, the fourth MOS transistor M4 can be an N-MOS transistor (model NX7002) that is on when the gate is low and off when the gate is high. The gate of the fourth MOS transistor M4 can be electrically connected to the source of the third MOS transistor M3 for receiving the second enable signal. The source of the fourth MOS transistor M4 can be electrically connected to the power supply terminal of the baseboard management control unit 22 through the third resistor R3 for receiving the power supply provided by the baseboard management control unit 22. The drain of the fourth MOS transistor M4 can be grounded (GND) as a current loop. The third resistor R3 can function to step down the preset voltage (e.g., 3-5V) power supply and supply power to the fourth MOS transistor M4 after stepping down. The size of the third resistor R3 can not be limited, for example, it can be 5-15KΩ.

[0040] Referring to Figure 3 In some embodiments, when the third MOS transistor M3 outputs the second enable signal, the fourth MOS transistor M4 enters an on state, in which the source of the fourth MOS transistor M4 can output a data clear signal to the central processing module 50. The central processing module 50 can enter a reset state according to the data clear signal to clear the system data stored therein and reset the system setting data in the central processing module 50.

[0041] In some embodiments, the central processing module 50 can include a central processing unit (CPU), a platform controller hub (PCH), a complex programmable logic device (CPLD), etc. The central processing unit (CPU) can be responsible for performing computing, control and data processing tasks, and is the core processing unit of the system. The platform controller hub (PCH) is part of the Intel chipset architecture, which is used to manage the connection and power functions of the CPU and other hardware such as memory, storage, peripherals, etc. The complex programmable logic device (CPLD) is a programmable digital integrated circuit used to implement specific logic functions.

[0042] In some embodiments, when the system needs to be reset, the signal output unit 23 can output a low-level power-off signal (AUX_ON=0) and maintain it for a predetermined time (for example, 10-50 seconds, and for example, 20-40 seconds). At this time, the second MOS tube M2 enters the off state due to insufficient gate-source voltage difference. When the second MOS tube M2 enters the off state, the gate of the first MOS tube M1 cannot receive a signal, so the second MOS tube M2 also enters the off state. Subsequently, the circuit between the power supply module 10 and the central processing module 50 is cut off, and the central processing module 50 can enter the ACPI G3 state (completely powered-off state, and mechanically closed).

[0043] In some embodiments, after the central processing module 50 enters the ACPI G3 state, the signal output unit 23 can generate a high-level reset signal and transmit it to the gate of the third MOS tube M3. At this time, the third MOS tube M3 can enter the on state, and then the fourth MOS tube M4 can also enter the on state and generate a data clear signal. At this time, the reset pin of the central processing module 50 can be pulled high to a high level (logic high) due to the data clear signal, triggering a CMOS clear action to clear the faulty system configuration data and restore the default system settings.

[0044] The application also provides a server, which can include the above-mentioned power supply system, and the power supply system can realize power supply and reset of the central processing module 50 inside the server.

[0045] Please refer to Figure 4 The application also provides a power supply method for a server, which can be applied to the above-mentioned power supply system of the server, and the power supply method can include the following steps: Step S10, the server needs to be restarted after an exception or firmware upgrade; Step S20, whether the BMC triggered software shutdown restart can be recovered, if not, then the next step; Step S30, whether the BMC triggered hardware shutdown restart can be recovered, if not, then the next step; Step S40, the BMC triggers whether the G3 state can be recovered, if not, the next step; Step S50, the BMC triggers the G3 state and triggers the CMOS clearing action, resets the system setting data in the central processing module.

[0046] In some embodiments, in step S10, the current state of the central processing module can be judged, when the server is in an abnormal state or firmware upgrade, the substrate management control module generates a corresponding power supply signal according to the external power supply instruction. In steps S20 and S30, the switch module can enter the on state according to the power supply signal to supply power to the central processing module. Among them, step S10, step S20, step S30 are the operations supported by the default BMC function, which will not be repeated here.

[0047] In some embodiments, in steps S40 and S50, it is judged whether the central processing module returns to the working state, when the central processing module is in an abnormal state or firmware upgrade, the substrate management control module generates a corresponding power-off signal according to the external power-off instruction; the switch module enters the off state according to the power-off signal to stop supplying power to the central processing module, and makes the central processing module enter the G3 state and trigger the CMOS clearing action.

[0048] In some embodiments, for steps S40 and S50, the remote server can be more thoroughly and safely recovered. The substrate management control unit 22 (BMC) power supply is completely independent of the auxiliary power supply of the central processing module 50. The power supply module 10 can continuously supply power to the substrate management control unit 22 through the first voltage conversion unit 21, and the substrate management control unit 22 is always on. The power supply module 10 can supply power to the central processing module 50 through the switch module 30 and the second voltage conversion unit 31, and the switch module 30 can be controlled by the substrate management control unit 22, thereby realizing the opening and closing of the switch module 30.

[0049] In some embodiments, in step S40, the substrate management control unit 22 (BMC) can trigger the AUX_ON signal to be 0 and maintain for a first preset time (for example, 10-50 seconds, and for example, 20-40 seconds), the switch module 30 (SW1) completely closes the auxiliary power supply of the central processing module 50, realizing the complete power-off state (G3 state) of the central processing module 50, and the substrate management control unit 22 (BMC) outputs the AUX_ON signal to be 1, the switch module 30 (SW1) opens the auxiliary power supply of the central processing module 50, and the central processing module 50 system recovers to ACPI S5 state without booting, and the subsequent server can operate according to the normal boot process.

[0050] In some embodiments, in step S50, the baseboard management control unit 22 (BMC) triggers the AUX_ON signal to be 0 to close the switch module 30 (SW1) and keep the second preset time (for example, 30-50 seconds, and for example, 30-40 seconds), the switch module 30 (SW1) completely closes the auxiliary power supply of the central processing module 50, and completely realizes the G3 state of the central processing module 50. In the G3 state, the baseboard management control unit 22 (BMC) can send a 1-second low-level pulse to the platform controller hub (PCH) of the central processing module 50 through the RTCRST signal to realize the clearing of CMOS, and then the baseboard management control unit 22 (BMC) outputs the AUX_ON signal to be 1 to open the auxiliary power supply of the central processing module 50. In the case of no booting, the central processing module 50 returns to the ACPI S5 state, and the subsequent server can operate according to the normal booting process.

[0051] It is worth noting that the trigger condition of the present application can be triggered by the administrator through a remote command, or can be automatically triggered by the system. For example, the administrator can initiate a power-down request of the G3 state through an IPMI command, a Redfish API, or a BMC Web interface. Alternatively, when the baseboard management control unit 22 detects a system deadlock, a specific hardware error, or a temperature out of control that cannot be recovered, the baseboard management control unit 22 automatically triggers according to a preset strategy.

[0052] In some embodiments, when the trigger condition is executed by the baseboard management control unit 22, if the system is in a booting state (S0), an emergency shutdown signal can be sent, for example, through an intelligent platform management interface (IPMI), to attempt to quickly but relatively orderly shut down the operating system. If this step fails or times out, the next step is continued. When AUX_ON=0, the baseboard management control unit 22 controls the GPIO (General Purpose Input / Output) pin output of the AUX_ON signal to be low. This signal is transmitted to the control electrode of the switch module, causing the switch module to immediately close. Then, the baseboard management control unit 22 maintains the state of AUX_ON=0 for a preset time. There are a large number of capacitors in the CPU system auxiliary power supply domain, and the preset holding time ensures that these capacitors have enough time to completely discharge through the on-board bleed resistor, and all related chips are completely disabled, eliminating any unstable state that may be maintained by residual charge. Then, AUX_ON=1 is restored. After the preset time, the baseboard management control unit 22 restores the AUX_ON signal to high, reopens the switch module, and the CPU auxiliary power supply domain is powered on again. Then, the state is restored. At this time, the main system hardware has experienced a complete power-down of the G3 state. After the system hardware self-checks, it will be stable in the ACPI S5 state and wait for the next booting instruction.

[0053] It can be seen that in the above scheme, the auxiliary power supply of the central processing module can be remotely cut off, and the G3 complete power-off state of the ACPI (Advanced Configuration and Power Interface) specification is simulated to realize deep operations such as CMOS clearing, system resetting, hardware resetting, and thus the remote power-off step is performed in compliance. Cutting off the auxiliary power supply completely can eliminate standby energy consumption in the shutdown state, reduce energy waste, and reduce the risk of hardware aging caused by long-term low-power operation of key components. By simulating the remote power-off and recovery process, manual on-site maintenance is replaced, significantly reducing the operation and maintenance cost and downtime of servers in remote areas. Furthermore, the present application can realize efficient energy management, and in remote data centers, it can also remotely cut off all power supplies (including auxiliary power supplies) of completely unused equipment to realize true zero power consumption and remotely wake up when needed. In particular, for AI models (such as large language models (LLM) and diffusion models), the cost of electric power operation is extremely high. The efficient energy management of the present application can complete more calculations under the same power consumption and heat dissipation budget, thereby promoting the development of AI performance, so energy management is directly related to the feasibility, technical scalability, and application universality of AI. In addition, the scheme of the present application can avoid complex timing logic problems and ensure that all operations comply with industry mandatory specifications, and in particular, it can reduce manual intervention and reduce maintenance costs.
