Description

Technical Field

[0001] The present invention relates to the technical field of servers, and in particular to a power-on method, device, equipment and medium. Background Art

[0002] When developing and designing servers, in order to improve their heat dissipation efficiency, simplify heat dissipation design, balance air volume distribution, save space and improve system redundancy, the server power supply and system fan are placed on the same side, but this may also bring the risk of power module fan reversal. Specifically, when the power module is replaced and repaired, the newly inserted power fan may reverse due to the air suction effect. If the reversal speed is high, the fan may not be pulled to the forward state after the power is powered on, resulting in a power fan fault alarm and the loss of server power supply redundancy.

[0003] To avoid the above situation, the current system architecture design will compare the power fan's anti-reversal capability and wind flow simulation value. If the requirements are not met, a control strategy will be introduced into the controller to monitor the power status in real time and control the fan to rotate forward at full speed. However, this strategy may cause the power fan power supply circuit current to increase instantaneously, or even damage the power fan or server power supply, which is not conducive to the stable operation of the server.

[0004] In view of the above problems, how to solve the problem that the server power supply power-on mode against wind will damage the power supply fan or server power supply, which is not conducive to the operation of the server, is an urgent problem to be solved by technical personnel in this field.

[0069] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0070] The core of the present invention is to provide a power supply power-on method, device, equipment and medium to solve the problem that the server power supply power-on method against wind will damage the power supply fan or server power supply, which is not conducive to the operation of the server.

[0071] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0072] In server R&D and design, in order to improve heat dissipation efficiency, simplify heat dissipation design, balance air volume distribution, save space and improve system redundancy, the server power supply and system fan are usually placed on the same side. However, this design may cause some problems. When the server fan is working, two airflow loops are generated: one is the main heat dissipation airflow loop between the server fan and the whole machine components, and the other is the airflow loop between the server fan and the internal air duct of the power module. The latter may affect the heat dissipation of the power module, because the server fan will produce a suction effect on the internal air duct of the power module, which is opposite to the active heat dissipation wind direction of the power module fan, and may cause the risk of reversal of the power module fan.

[0073] Taking the replacement and maintenance process of the server power supply as an example, it is assumed that the server power supply module adopts a 1+1 redundant configuration. Under normal circumstances, the server system fan maintains normal speed. However, if the server works under extreme conditions, the system fan will be at the highest full speed state. At this time, if one of the power supply modules is replaced and repaired, before the new power supply is inserted into the server and the power supply line is not connected, due to the suction effect of the server fan on the air duct of the power supply module, the fan of the new server power supply will reverse with the suction direction of the system fan. If the reverse speed of the fan of the newly inserted power supply in the server is high, after the power supply is powered on, it may not be possible to rely on the anti-reverse starting force of the power supply fan to pull the power supply fan to the forward state. This will cause the server power supply to be powered on and the fan will be detected to be in the reverse state for more than the threshold time, and then report the power supply fan fault alarm, which will cause the output of the newly inserted power supply to be powered off and the server power supply redundancy to disappear. If the server is working under complex working conditions at this time, it may cause the server system to lose power and shut down, affecting the reliability of the server operation, and even causing a major safety accident in the computer room.

[0074] In order to solve this problem, when designing the server system architecture, the system cooling engineer will simulate the airflow conditions of the air inlet on one side of the server power supply gold finger and compare it with the anti-reverse airflow value of the server power supply fan. If the anti-reverse capability of the server power supply fan is greater than the airflow simulation value, it is considered that the server power supply anti-reverse capability meets the system design requirements and no special air duct design is required. If the anti-reverse capability of the server power supply fan is less than the airflow simulation value, a dedicated control strategy for the server power supply fan will be imported into the server complex programmable logic device (CPLD) version. This strategy will monitor the input power supply and in-place status of the system power supply in real time. When it is detected that the power supply is in the in-place state and the input power supply is restored, the system CPLD will immediately issue a fan control command to the server power supply, commanding the power supply fan to rotate forward at full speed, so as to achieve the server power supply fan to rotate forward quickly from the reverse state, and ensure the normal output power supply after the power supply is powered on.

[0075] However, when the anti-reversal capability of the newly powered-on power supply fan of the server is less than the wind flow simulation value, the above strategy may cause the current of the power supply fan power supply circuit to increase instantaneously, and in severe cases, it may exceed the overcurrent limit of the power supply fan power supply circuit, and finally cause the power supply fan to fail due to overcurrent damage of the MOS tube of its power supply circuit, so that the newly replaced power supply of the server is damaged and cannot be powered on normally. In order to solve the above problem, the present invention provides a power supply power-on method.

[0076] It should be noted that the method provided by the present invention is applied to a host computer. It is understandable that the host computer is in communication with the server node, can receive and pass the networking request of the server node on the same side of the power supply and system fan, and subsequently manage and control the server node.

[0077] Figure 1 A flow chart of a power-on method provided by an embodiment of the present invention. Figure 1 As shown, the method includes:

[0078] S10: When receiving a power off and replacement command for a server node, start a fault detection for the server node to determine whether the server node has a fault; if not, proceed to step S11;

[0079] Specifically, when the operation and maintenance personnel need to power off and replace the initial power supply of the server node, a power supply power off and replacement command for the initial power supply is issued. At this time, based on the power supply power off and replacement command, fault detection of the server node is started to determine whether the server node has a fault.

[0080] It should be noted that the fault detection of the server node involves the detection of multiple key information of multiple components of the server node. The specific process of the fault detection of the server node is not limited in this embodiment and depends on the specific implementation situation. Only when the server node passes the fault detection and confirms that the server node is normal, the subsequent steps are carried out. Otherwise, the power supply needs to be disconnected and replaced, so as to avoid abnormal power failure of the server and affect the normal operation of the server.

[0081] S11: Replace the initial power supply of the server node with the target power supply, and run the overcurrent protection module and the speed and rotation direction monitoring module of the target power supply.

[0082] Wherein, the overcurrent protection module is arranged in the power supply fan power supply circuit of the target power supply.

[0083] Furthermore, when it is confirmed that the server node is normal, the initial power supply of the server node is replaced with the target power supply, and the overcurrent protection module and the speed and rotation direction monitoring module of the target power supply are operated.

[0084] It should be noted that the overcurrent protection module is arranged in the power supply fan power supply circuit of the target power supply, and its function is to supplement the overcurrent protection mechanism of the server power supply fan power supply circuit, so as to prevent the instantaneous increase of the current in the power supply fan power supply circuit from damaging the power supply fan or the server power supply. In this embodiment, the specific structure of the overcurrent protection module is not limited, and it depends on the specific implementation situation. In addition, the function of the speed and rotation direction monitoring module is to detect the speed and rotation direction of the power supply fan of the target power supply. In this embodiment, the specific structure of the speed and rotation direction monitoring module is not limited, and it depends on the specific implementation situation.

[0085] S12: Obtain the fan speed and fan rotation direction of the target power supply through the speed and rotation direction monitoring module.

[0086] S13: Determine and execute a fan control strategy of the target power supply according to the fan speed and fan rotation direction of the target power supply, and control the target power supply to power on.

[0087] Subsequently, the fan speed and fan rotation direction of the target power supply are obtained through the speed and rotation direction monitoring module. It is understandable that when the target power supply is replaced, affected by the rotation of the server fan, the power supply fan of the target power supply may be in a stationary state, or may be in a reverse rotation state at different speeds. In order to avoid the instantaneous increase in the power supply fan power supply circuit current caused by the full speed rotation of the power supply fan, or even exceeding the overcurrent limit of its fan power supply circuit, which ultimately causes the newly added power supply fan in the server to fail due to overcurrent damage to the MOS tube of its power supply circuit, it is necessary to determine and execute the fan control strategy of the target power supply according to the fan speed and fan rotation direction of the target power supply, and control the target power supply to power on, thereby realizing adaptive control of power on.

[0088] It should be noted that in this embodiment, there is no restriction on the specific method for obtaining the fan speed and fan rotation direction of the target power supply, and there is no restriction on the specific process of determining and executing the fan control strategy of the target power supply based on the fan speed and fan rotation direction of the target power supply, which depends on the specific implementation situation.

[0089] In this embodiment, before replacing the power supply of the server node, the fault detection of the server node is performed to confirm that there is no fault in the server node before the power supply replacement is performed, thereby avoiding abnormal power failure of the server and affecting the normal operation of the server. When replacing the power supply of the server node, the power supply fan power supply circuit of the replaced target power supply has an overcurrent protection module, which solves the problem of the lack of overcurrent protection mechanism of the server power supply fan power supply circuit, and can avoid the instantaneous increase of the current in the power supply fan power supply circuit to damage the power supply fan or the server power supply; at the same time, a speed and rotation direction monitoring module is set to monitor the speed of the rotation direction of the power supply fan of the target power supply; when the target power supply is powered on against the wind, the corresponding fan control strategy is set according to the monitored rotation direction and speed of the power supply fan, and the target power supply is controlled to be powered on, realizing the adaptive control of the server power supply against the wind, and improving the server maintenance efficiency.

[0090] Based on the above embodiments, in some embodiments, starting fault detection on a server node to determine whether the server node has a fault includes:

[0091] S101: Acquire key information of key components of a server node;

[0092] Among them, the key components include at least the central processing unit, hard disk, graphics processor and power supply; the key information includes at least temperature, power consumption, rotation speed and working status;

[0093] S102: storing each key information into a temporary storage area for operating system model information;

[0094] S103: Compare each key information with the corresponding system standard data range to determine whether the key information is within the corresponding system standard data range; if so, proceed to step S104; if not, proceed to step S106;

[0095] S104: Confirm that key information is normal and that the server node is normal;

[0096] S105: storing the key information in the formal storage area of ​​the operating system model information;

[0097] S106: Confirm that the key information is abnormal and that the server node is faulty;

[0098] S107: Determine the fault type and fault cause of the abnormal key information according to the fault type standard library;

[0099] S108: The fault type and fault cause are stored in the operating system model information fault storage area.

[0100] Specifically, in order to determine whether a server node has a fault, key information of key components of the server node is specifically obtained. It should be noted that the key components of the server node in this embodiment include at least a central processing unit, a hard disk, a graphics processor, and a power supply, and may also include other components, which are not limited in this embodiment. The key information of the key components should at least include temperature, power consumption, rotation speed, and working status, and may also include other information, which is not limited in this embodiment. Each key information is stored in the temporary storage area of ​​the operating system model information for temporary storage.

[0101] Further, each key information is compared with the corresponding system standard data range to determine whether the key information is within the corresponding system standard data range. If it is confirmed that the key information is within the corresponding system standard data range, the key information is confirmed to be normal, and the server node is confirmed to be normal, and the key information can be further stored in the running system model information formal storage area for formal storage. If it is confirmed that the key information is not within the corresponding system standard data range, the key information is confirmed to be abnormal, and the server node is confirmed to have a fault. At this time, it is necessary to determine the fault type and cause of the abnormal key information according to the fault type standard library. It can be understood that the fault type standard library contains server fault types and causes corresponding to a variety of abnormal archived data. In the specific implementation, it is only necessary to combine the key information with the fault type standard library to determine the fault type and cause of the abnormal key information. Finally, the fault type and cause of the fault are stored in the running system model information fault storage area, so that the operation and maintenance personnel can view the cause of the server node fault in the running system model information fault storage area and perform corresponding maintenance operations.

[0102] In this embodiment, key information of key components of the server node is obtained; each key information is stored in a temporary storage area for the operating system model information; each key information is compared with the corresponding system standard data range to determine whether the key information is within the corresponding system standard data range; if so, the key information is confirmed to be normal and the server node is normal; the key information is stored in a formal storage area for the operating system model information; if not, the key information is confirmed to be abnormal and the server node is confirmed to have a fault; the fault type and fault cause of the abnormal key information are determined according to a fault type standard library; the fault type and fault cause are stored in the fault storage area for the operating system model information, thereby realizing fault detection of the server node.

[0103] Figure 2 A circuit diagram of an overcurrent protection module provided by an embodiment of the present invention. Figure 2 As shown, the overcurrent protection module includes: a first resistor R1, a low-frequency noise capacitor C1, a high-frequency filter capacitor C2, a thermistor R2 and an electronic delay relay K;

[0104] A first end of the first resistor R1 is connected to a common end formed by a first end of the low-frequency noise capacitor C1, a first end of the high-frequency filter capacitor C2 and a first end of the thermistor R2, and a second end of the low-frequency noise capacitor C1 and a second end of the high-frequency filter capacitor C2 are both grounded;

[0105] The second end of the thermistor R2 is connected to the first end of the electronic time delay relay K; the control end of the electronic time delay relay K is connected to the host computer;

[0106] Among them, the second end of the first resistor R1 is connected to the power supply fan power supply of the target power supply as the input end of the overcurrent protection module, and the second end of the electronic delay relay K is connected to the power supply fan load end of the target power supply as the output end of the overcurrent protection module.

[0107] Specifically, in this embodiment, the overcurrent protection module is arranged in the power supply fan power supply circuit of the target power supply, and is mainly composed of a first resistor R1, a low-frequency noise capacitor C1, a high-frequency filter capacitor C2, a thermistor R2 and an electronic delay relay K. The power supply fan load end of the target power supply is equivalent to a capacitor C3 and a resistor R3.

[0108] The low-frequency noise capacitor C1 can be a 1uF to 10uF decoupling capacitor to reduce the low-frequency noise of the power supply line; the high-frequency filter capacitor C2 can be a 0.01uF to 0.1uF decoupling capacitor to filter out the high-frequency interference conducted along the power supply line of the target power supply fan. The low-frequency noise capacitor C1 and the high-frequency filter capacitor C2 work together to replenish the peak current required by the server power supply fan when it suddenly works at high speed.

[0109] Thermistor R2 and high-frequency filter capacitor C2 are used together. When the power fan of the target power supply suddenly works at high speed, causing the low-frequency noise capacitor C1 and high-frequency filter capacitor C2 to discharge quickly, resulting in an instantaneous power supply spike current in the power supply fan power supply line, and the instantaneous power supply spike current exceeds the overcurrent protection limit of the power supply fan power board, thermistor R2 will quickly heat up and increase its resistance to limit the peak current of the power supply fan power supply line, which to a certain extent protects the power supply fan power supply circuit from overcurrent damage. When the current of the power supply fan power supply line returns to below the limit, thermistor R2 will automatically return to a low resistance state, and the power supply line will resume normal operation.

[0110] The electronic time delay relay K is the last link of the overcurrent protection of the power supply circuit of the target power supply fan. When the power supply fan of the target power supply is working normally, the electronic time delay relay K is in a long closed state. When the relay current sensor detects that the power supply fan power supply line current still exceeds the line current warning value after passing through the thermistor R2, the electronic time delay relay K starts to start separation preparation. During the relay separation preparation stage, the relay current sensor will continue to monitor the line current. If the line current continues to increase and exceeds the relay line current limit, the relay will start the separation action and the relay will be disconnected to achieve overcurrent protection of the server power supply fan power supply line; if the relay current sensor monitors that the line current does not continue to increase and return to normal value during the relay separation preparation stage, the relay will exit the separation preparation state. In this way, overcurrent protection of the power supply circuit of the target power supply fan is achieved.

[0111] It should be noted that in this embodiment, there is no restriction on the parameters of the specific models of the electronic components in the overcurrent protection module, which depends on the specific implementation situation.

[0112] Figure 3 A schematic diagram of a speed and rotation direction monitoring module provided by an embodiment of the present invention. Based on the above embodiments, in some embodiments, such as Figure 3 As shown, the speed and rotation direction monitoring module includes: a power fan patch magnet 10, a first Hall sensor 11 and a second Hall sensor 12;

[0113] The power supply fan patch magnet is arranged on the blade surface of the power supply fan of the target power supply in the exhaust direction; the first Hall sensor and the second Hall sensor are respectively arranged on the power supply fan frame of the target fan at preset angle intervals, and are arranged opposite to the power supply fan patch magnet; the first Hall sensor and the second Hall sensor are both connected to the host computer for communication.

[0114] Specifically, the speed and rotation direction monitoring module in this embodiment is mainly composed of a power fan patch magnet, a first Hall sensor and a second Hall sensor. Among them, the power fan patch magnet is set on the fan blade surface of the power fan of the target power supply in the exhaust direction; the first Hall sensor and the second Hall sensor are respectively set on the power fan frame of the target fan at preset angle intervals, and are arranged opposite to the power fan patch magnet; the first Hall sensor and the second Hall sensor are both connected to the host computer for communication. In this embodiment, there is no restriction on the preset angle interval, for example, it can be 45 degrees or 90 degrees.

[0115] When the power fan of the target power supply rotates, the power fan patch magnet will pass through the first Hall sensor and the second Hall sensor in sequence. During this cycle, the two Hall sensors will respectively generate specific sequence signals and corresponding timestamp data in real time; the sequence signal and corresponding timestamp data will be temporarily stored in the temporary storage area of ​​the server power register to facilitate the subsequent determination of the fan speed and rotation direction.

[0116] Correspondingly, the fan speed and fan rotation direction of the target power supply are obtained through the speed and rotation direction monitoring module, including:

[0117] S121: monitoring a first sequence signal transmitted by a first Hall sensor, and determining a first timestamp corresponding to the first sequence signal;

[0118] S122: monitoring a second sequence signal transmitted by a second Hall sensor, and determining a second timestamp corresponding to the second sequence signal;

[0119] S123: Determine a first time interval from receiving the first sequence signal to receiving the second sequence signal according to the first timestamp and the second timestamp;

[0120] S124: Determine a second time interval from receiving the second sequence signal to receiving the first sequence signal according to the second timestamp and the first timestamp;

[0121] S125: determining a rotation direction of a fan of the target power supply according to a magnitude relationship between the first time interval and the second time interval;

[0122] S126: Add the first time interval and the second time interval to obtain the rotation time of the power supply fan of the target power supply;

[0123] S127: Determine the fan speed of the target power supply according to the rotation time of the power supply fan of the target power supply.

[0124] Specifically, in order to determine the fan speed and fan rotation direction of the target power supply, it is necessary to monitor the first sequence signal transmitted by the first Hall sensor and determine the first timestamp corresponding to the first sequence signal; monitor the second sequence signal transmitted by the second Hall sensor and determine the second timestamp corresponding to the second sequence signal. It is understandable that, since the power supply fan is constantly rotating, the first sequence signal and the second sequence signal will be continuously received, and the timestamps corresponding to the two sequence signals will be continuously recorded.

[0125] Further, based on the first timestamp and the second timestamp, the first time interval from receiving the first sequence signal to receiving the second sequence signal is determined; at the same time, based on the second timestamp and the first timestamp, the second time interval from receiving the second sequence signal to receiving the first sequence signal is determined. According to the size relationship between the first time interval and the second time interval, the fan rotation direction of the target power supply is determined. Specifically, assuming that the first Hall sensor is in the counterclockwise direction of the second Hall sensor, if the first time interval is less than the second time interval, it is considered that the power supply fan is rotating in the clockwise direction at this time. If the first time interval is greater than the second time interval, it is considered that the power supply fan is rotating in the counterclockwise direction at this time. It should be noted that in this embodiment, there is no restriction on the forward rotation direction of the power supply fan of the target power supply, and the forward rotation direction of the power supply fan needs to be determined in advance, so as to determine whether it is rotating forward or reverse after obtaining the rotation direction of the power supply fan.

[0126] Finally, the first time interval and the second time interval are added to obtain the rotation time of the power supply fan of the target power supply, and the fan speed of the target power supply is determined according to the rotation time of the power supply fan of the target power supply. In this way, the fan speed and fan rotation direction of the target power supply are obtained.

[0127] Based on the above embodiments, in some embodiments, determining and executing a fan control strategy of a target power supply according to a fan speed and a fan rotation direction of the target power supply, and controlling the target power supply to power on, includes:

[0128] S131: judging whether the power supply fan rotates in the reverse direction according to the fan speed and the fan rotation direction of the target power supply; if it is confirmed that the power supply fan of the target power supply does not rotate or rotates forward, proceeding to step S133; if it is confirmed that the power supply fan of the target power supply rotates in the reverse direction, proceeding to step S132;

[0129] S132: Determine whether the fan speed of the target power supply is not greater than the power supply fan anti-reversal speed threshold; if it is confirmed that the fan speed of the target power supply is not greater than the power supply fan anti-reversal speed threshold, proceed to step S133; if it is confirmed that the fan speed of the target power supply is greater than the power supply fan anti-reversal speed threshold, proceed to step S134;

[0130] S133: directly control the target power supply to power on;

[0131] S134: Control the power supply fan of the target power supply to rotate at a target speed, and control the target power supply to power on;

[0132] The target rotation speed is not less than the anti-reversal rotation speed threshold of the power supply fan.

[0133] In a specific implementation, in order to determine and execute the fan control strategy of the target power supply and control the target power supply to be powered on, it is specifically determined whether the power supply fan rotates in the reverse direction according to the fan speed and the fan rotation direction of the target power supply. For example, when the power supply fan of the target power supply rotates clockwise as positive rotation, then when the power supply fan of the target power supply rotates counterclockwise, it is considered that the power supply fan rotates in the reverse direction.

[0134] It should be noted that in order to better judge the rotation status of the power supply fan, the rotation status can be judged after the target power supply is replaced and inserted into the slot of the initial power supply and the corresponding power supply in place signal is restored, and the preset time is postponed to wait for the rotation status of the power supply fan of the target power supply to stabilize. In this embodiment, there is no limit on the preset time, for example, it can be set to 3 minutes. This can effectively improve the accuracy of the judgment of the rotation status of the power supply fan.

[0135] If it is confirmed that the power fan of the target power supply does not rotate or rotates forward, it is considered that the current target power supply does not involve powering on against the wind, and the target power supply can be directly controlled to power on. If it is confirmed that the power fan of the target power supply rotates in the reverse direction, it is necessary to determine whether the fan speed of the target power supply is not greater than the power fan anti-reverse speed threshold. It should be noted that the power fan anti-reverse speed threshold refers to the speed value at which the power fan can resist reverse startup. When the reverse rotation speed of the power fan is lower than the power fan anti-reverse speed threshold, the power fan has the ability to return to the forward rotation state. When the reverse rotation speed of the power fan is not lower than the power fan anti-reverse speed threshold, the power fan cannot return to the forward rotation state. In this embodiment, there is no restriction on the size of the power fan anti-reverse speed threshold, which depends on the specific implementation situation.

[0136] Therefore, if it is confirmed that the fan speed of the target power supply is not greater than the power supply fan anti-reversal speed threshold, it is considered that the power supply fan is capable of recovering to the state of forward rotation, and the target power supply can be directly controlled to power on. If it is confirmed that the fan speed of the target power supply is greater than the power supply fan anti-reversal speed threshold, it is considered that the power supply fan cannot recover to the state of forward rotation, and the power supply fan of the target power supply is controlled to rotate at the target speed, and the target power supply is controlled to power on. It should be noted that the target speed is not less than the power supply fan anti-reversal speed threshold. In this embodiment, there is no restriction on the size of the target speed, which depends on the specific implementation situation.

[0137] In this way, the determination and execution of the fan control strategy of the target power supply is achieved, so as to better control the power-on of the target power supply.

[0138] Based on the above embodiments, in some embodiments, controlling the power supply fan of the target power supply to rotate at a target speed includes:

[0139] S135: monitoring the fan rotation direction of the target power supply through a rotation speed and rotation direction monitoring module;

[0140] S136: Determine whether the rotation direction of the fan of the target power supply has been restored to forward rotation; if the rotation direction of the fan of the target power supply has been restored to forward rotation, then the process ends; if the rotation direction of the fan of the target power supply has not been restored to forward rotation, then the process proceeds to step S137;

[0141] S137: Control the power supply fan of the target power supply to increase the current target speed by a preset speed increment to obtain a new target speed;

[0142] S138: Control the power supply fan of the target power supply to rotate at the new target speed, and return to step S136.

[0143] Specifically, when the fan speed of the target power supply is greater than the power supply fan anti-reversal speed threshold, the power supply fan of the target power supply is controlled to rotate at the power supply fan anti-reversal speed threshold as the target speed. At this time, the fan rotation direction of the target power supply is monitored by the speed and rotation direction monitoring module to determine whether the fan rotation direction of the target power supply has resumed forward rotation. If the fan rotation direction of the target power supply has resumed forward rotation, the power supply fan control and power-on process is terminated.

[0144] If the fan rotation direction of the target power supply has not resumed forward rotation, the power supply fan of the target power supply is controlled to increase the current target speed by a preset speed increment to obtain a new target speed. For example, if the power supply fan anti-reversal speed threshold is 10,000 rpm, the current target speed is increased by a speed increment of 2,000 rpm to obtain a new target speed of 12,000 rpm. The power supply fan of the target power supply is further controlled to rotate at the new target speed, and the process returns to the step of determining whether the fan rotation direction of the target power supply has resumed forward rotation until it is detected that the power supply fan of the target power supply has resumed forward rotation. In this way, it is ensured that the target power supply resumes forward rotation, preventing the server power supply from being damaged by overcurrent.

[0145] Based on the above embodiments, in some embodiments, the following further includes:

[0146] S14: monitoring the operating status of the server node through the mobile terminal;

[0147] S15: When a server node fails, a fault alarm prompt message is output via a mobile terminal.

[0148] In the specific implementation, the mobile terminal can also be set to monitor the operating status of the server node, including the alarm information of the key components such as the central processor, hard disk, and power supply of the server node, to provide reliability information support for the replacement and maintenance of the server power supply in the computer room or the switching process of the power supply line of the server in the computer room. When a server node fails, the mobile terminal outputs the fault alarm prompt information, thereby prompting the operation and maintenance personnel to maintain the fault.

[0149] In addition, the mobile terminal can also output feedback information related to power outage replacement. When the target power supply completes the replacement of the initial power supply and is powered on, the mobile power supply can feedback the prompt information of the successful power-on of the target power supply in the server node, and record the process information of this power-on, so that the operation and maintenance personnel can better understand the maintenance status of the server node.
