[0002] In the mainstream design of switches or servers, fan modules of 4056 or 8086 sizes are generally used for system heat dissipation of switches or servers. As core heat dissipation components in switches or servers, whether the performance of the fan modules is stable and whether the specification parameter consistency meets the requirements will directly determine whether the entire switch or server can reliably operate.

[0003] Currently, system manufacturers such as switches or servers mainly rely on factory detection of fan module manufacturers for incoming inspection of fan modules. For example, only the appearance of the incoming fan module is checked during factory detection, and whether the function of the fan module and the FRU (Field Replaceable Unit, field replaceable unit) burning information are correct are not checked, and further, the missed detection in these functions will cause the functionally abnormal fan module to flow to the whole machine assembly link, further causing production test failure and affecting the production efficiency of the switch / server.

[0070] In the embodiment, each gold finger unit is connected to the main control unit and the voltage and current detection unit on one side, and connected to the fan module or the adapter card unit on the other side, for transmitting the control signals and power signals from the main control unit and the voltage and current detection unit to the fan module / adapter card unit.

[0071] In addition, each gold finger unit is further configured to transmit the in-place signal and the rotating speed feedback signal of the fan module or the adapter card unit to the main control unit.

[0075] The first GPIO pin (such as GPIO-A1) of the plurality of GPIO pins is connected with the first interface, and is used for the master control unit to transmit a first control signal to the first gold finger unit to control the fan rotating speed of the fan module; the second GPIO pin of the plurality of GPIO pins is connected with the second interface, and is used for the master control unit to transmit a first detection signal to the first gold finger unit to detect the fan rotating speed of the fan module; the second I2C interface of the plurality of I2C interfaces is connected with the third interface, and is used for the master control unit to transmit a second detection signal to the first gold finger unit to check the FRU burning information; the third GPIO pin of the plurality of GPIO pins is connected with the fourth interface, and is used for the master control unit to transmit a third detection signal to the first gold finger unit to detect the fan direction of the fan module; the fourth GPIO pin of the plurality of GPIO pins is connected with the fifth interface, and is used for the master control unit to transmit an in-place signal to the first gold finger unit to detect whether the fan module is inserted on the first gold finger unit; and the first I2C interface of the plurality of I2C interfaces is connected with the first voltage and current detection unit, and is used for the master control unit to transmit a second control signal to the first voltage and current detection unit to control the first voltage and current detection unit to start power detection and report the detection result.

[0076] The first voltage and current detection unit is connected with the first gold finger unit, and is used for detecting whether the power of the fan module is within the rated power.

[0077] In addition, when the fan module connected with the first gold finger unit is a double-rotor module, the number of the first GPIO pin and the second GPIO pin arranged on the master control unit is two, and the number of the first interface and the second interface arranged on the first gold finger unit is two.

[0081] The GPIO-A6 pin of the master control unit is connected with the FAN-A1_PRESENT of the first golden finger unit, for detecting whether the fan module 1 is inserted into the first golden finger unit. One detection method is: when the first golden finger unit is not inserted with the fan module 1, the bit signal (PRESENT) is high; when the fan module is inserted into the first golden finger unit, the bit signal becomes low, so the master control unit can detect the high and low levels of the FAN-A1_PRESENT bit signal by using the GPIO-A6 pin, to determine whether the fan module is inserted into the first golden finger unit.

[0088] Optionally, the display unit can be a liquid crystal display screen LCD.

[0089] The key unit is connected with the GPIO-x pin of the main control unit, and is used for system reset of the test fixture, operation of the upper computer and / or operation of the display unit. Optionally, the key unit is a 4-bit key unit.

It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0098] In the embodiment, a detection method for a fan module is provided, which can be used for the jig shown in the above Figure 1 or Figure 2 The jig shown in the above Figure 3 is a flowchart of a detection method for a fan module according to an embodiment of the application, and the flowchart includes the following steps:

[0099] Step S101: In the test mode of the jig, it is detected whether a fan module is inserted into at least one gold finger unit.

[0100] The method provided by the embodiment can be executed by the above-mentioned main control unit, and the test mode of the jig can be triggered and started by a user or automatically started after the system is started. The test mode refers to a mode of starting the function check of the fan module to be connected.

[0101] Specifically, an embodiment of detecting whether a fan module is inserted into at least one gold finger unit is that whether the in-place signal (such as FAN-A1_PRESENT) on each gold finger unit is low is detected by means of the GPIO pin in the main control unit, if it is low, it is determined that a fan module is inserted into the corresponding gold finger unit; if it is detected as high, it is determined that no fan module is inserted.

[0102] Step S102: If it is detected that the first fan module is inserted on the first gold finger unit, read the FRU information inside the first fan module and parse the FRU information.

[0103] If the detection signal FAN-A1_PRESENT in step S101 is low, it is determined that the first fan module (i.e. fan module 1) is inserted on the first gold finger unit. The host unit sends a detection signal to the FAN-A1 I2C of the first gold finger unit, reads the FRU information in the fan module 1, and parses the FRU information.

[0104] The FRU information inside the fan module can include basic identity information, technical specification information, compatibility information, maintenance and troubleshooting information, and other information.

[0105] Specifically, the basic identity information includes model number and serial number: such as the unique identifier of the fan module, used to distinguish different fan modules; manufacturer information: the name of the manufacturer that produces the fan module, etc. The technical specification information includes speed range, air volume and air pressure, power consumption, etc. The compatibility information can include: supported server models: such as listing the server models that the fan module can be installed and work normally. And interface standards: the interface type and specification of the fan module connected to the server mainboard or other components, such as 4-pin PWM interface, etc. The maintenance and troubleshooting information includes replacement period, fault indicator light, fault diagnosis code, etc. In addition, other information includes but is not limited to production date and batch number: the production date and batch number of the fan module, which helps to track the production process and quality control of the product.

[0106] The above FRU information or FRU data: Some fan modules store FRU information in non-volatile memory (such as EEPROM), including product number, serial number, manufacturer information, etc. These information can be read and managed through the BMC (Baseboard Management Controller) of the server or other management tools.

[0107] Step S103: Determine that the first fan module is an already adapted fan module.

[0108] The host unit determines whether the fan module 1 is a fan module that has been adapted in advance according to the parsed FRU information. One possible implementation is that data read verification is to read the data burned from the target memory and compare it with the original data or expected value to determine whether the data is consistent. Use the burning tool or software to read the data from the target memory and compare it with the corresponding value in the frb (Flash Raw Binary), if consistent, it is determined that the fan module has been adapted; if not consistent, it is determined that the fan module is not adapted.

[0109] Step S104: If yes, that is, in the case of determining that the first fan module is an adapted fan module after parsing the FRU information, at least one control signal is sent to the first fan module through the first golden finger unit. Wherein, the at least one control signal is used to control the fan speed to be adjusted in a configured speed stepping mode and the fan speed to be detected.

[0110] Specifically, the main control unit sends a control signal to the FAN-A1_PWM, FAN-A2_PWM interface of the first golden finger unit, which is used to control the fan speed of the fan module 1; sends at least one detection signal to the FAN-A1_TECH, FAN-A2_TECH interface of the first golden finger unit, which is used to detect the fan speed of the fan module 1; and sends an I2C signal to the voltage and current detection unit A through the I2C-A1 interface, so as to start the power detection function of the voltage and current detection unit A to the fan module 1.

[0111] Step S105: Receive the detection result reported by the first voltage and current detection unit, and determine the running state of the first fan module according to the detection result.

[0112] In one possible implementation of the embodiment, step S105: receiving the detection result reported by the first voltage and current detection unit, and determining the running state of the first fan module according to the detection result, specifically includes:

[0113] Step S105-1: receiving the detection result reported by the first voltage and current detection unit, wherein the detection result includes one or more of the actual speed, voltage and current, and fan speed adjustment time of the first fan module.

[0114] Step S105-2: judging whether one or more of the actual speed, voltage and current, and fan speed adjustment time is within a preset range. The preset ranges corresponding to the actual speed, voltage and current, and fan speed adjustment time respectively can be the same or different.

[0115] Step S105-3: If yes, it is determined that the running state of the first fan module is normal, and the information that the running state is normal is displayed through the host computer interface unit or the display unit.

[0116] Step S105-4: If there is at least one not within the preset range, it is determined that the running state of the first fan module is abnormal, and the abnormal running state is reported or alarmed.

[0117] The fan module detection method provided by the embodiment can not only automatically complete function verification of the fan module, but also has FRU information detection function, fan rotating speed step-by-step speed regulation and rotating speed detection function, realizes automatic detection of whether the actual fan rotating speed under different rotating speed control signals is within a normal range, and the accurate detection and control not only helps to evaluate the performance of the fan module, but also ensures that the fan can accurately adjust the rotating speed according to the requirement in actual application, and improves the overall performance and stability of the system.

[0118] In addition, the method is suitable for incoming detection of fan modules of different structural types and different electrical specifications, has strong universality and low cost.

[0119] In a possible implementation, before the step S101 of detecting whether the at least one fan module is inserted into the at least one golden finger unit after the jig starts the test mode, the step S101 further includes: configuring the fan rotating speed step-by-step mode and whether to simulate hot plug start of the at least one fan module to be detected, generating configuration information, and saving the configuration information.

[0120] In another implementation, after the step S103 of analyzing the FRU information by the master control unit, the step S103 further includes: in a case that the first fan module is determined to be a non-adapted fan module after the FRU information is analyzed, setting a rated parameter of the first fan module, and the rated parameter includes at least one of the rated voltage, the rated current, the rated rotating speed and the relationship between the duty cycle and the rotating speed.

[0121] The master control unit controls the first fan module to operate according to the set rated parameter through the first golden finger unit, and monitors the operating state of the first fan module.

[0122] The fan module detection method will be described below in combination with a specific embodiment.

[0123] As shown in FIG. 1, it is a flowchart of another fan module detection method according to an embodiment of the application. The method is applied to the jig shown in FIG. 1, and the method specifically includes: Figure 4 Figure 2 Starting the detection flow of the fan module.

[0124] Step S201: After the equipment is normally powered on and initialization is completed, entering step S202.

[0125] Step S202: According to the actual situation of the detection site, selecting to use the upper computer operation or the local touch screen operation, and entering step S203.

[0126] Step S202: According to the actual situation of the detection site, selecting to use the upper computer operation or the local touch screen operation, and entering step S203.

[0127] ​Step S203: The host device selects a test mode. Generally, the default test mode is an intelligent mode, which is a one-key automatic test mode of the fan module function. In addition to the intelligent mode, there is also a manual mode, which needs to manually set the fan speed and other configuration parameters, and manually detect the FRU burning information and speed of the fan module.

[0128] In this step, when the intelligent mode is started, step S204 is executed; if the manual mode is selected, step S213 is executed.

[0129] Step S204: Configure the fan speed stepping mode, whether to simulate the fan module hot plug start, and other information, generate a configuration option, and save the configuration option in a storage medium or memory.

[0130] Specifically, if there is a required test configuration, it is directly selected. If there is no required test configuration, whether the fan module has FRU information, the fan speed stepping mode, and whether to simulate the fan module hot plug start are configured, the configuration is saved to a storage unit for subsequent test calling, and step S205 is entered.

[0131] In this embodiment, the fan speed stepping mode in the fan module includes: stepping every 1%, 5%, 10%, or running at 35%, 65%, 100% of the maximum speed ratio. It should be understood that more or fewer stepping modes can also be set, which are not limited in this embodiment.

[0132] Step S205: The host unit detects whether the fan module is inserted. This step corresponds to step S101 of the embodiment shown in the foregoing Figure 3 The specific embodiment process is described in the foregoing embodiment description, which is not repeated here.

[0133] If no fan module is inserted on at least one golden finger unit, step S206 is entered; if one or more fan modules are inserted on the golden finger unit, step S207 is entered.

[0134] Step S206: The host computer serial port displays or the LCD liquid crystal displays a fan module not in place alarm, and the detection program automatically skips the subsequent detection process of the fan module in the slot. At this time, only the inserted fan module is detected, and step S207 is entered.

[0135] Step S207: If the fan module is inserted, the host unit reads the internal FRU information of the fan module through the I2C interface, and analyzes the FRU information. This step corresponds to step S102 of the foregoing embodiment.

[0136] Step S208: Determine whether it is an adapted fan module.

[0137] If the FRU information is parsed as a non-adapted fan module, step S210 is entered; if the FRU is parsed as an adapted fan module, step S209 is entered.

[0138] Step S210: The host computer serial port or LCD liquid crystal prompts for fan module non-adaptation, at which time the rated parameters of the fan module need to be input, including rated voltage, current, and speed-duty ratio relationship, and step S209 is entered.

[0139] Step S209: The main control unit performs speed regulation and speed detection according to the configured fan speed stepping mode. This includes but is not limited to real-time monitoring of fan speed feedback, voltage and current, automatically capturing parameters in the adaptation list, judging whether the actual fan speed, fan speed regulation time, and fan current are within the specification defined range, and if the test results are all passed, using the host computer serial port display or LCD liquid crystal display to output in real time; if the test results are abnormal, an alarm prompt is issued, and step S211 is entered.

[0140] Step S211: If the fan hot plug start detection item has been configured, the main control unit controls to turn off the power of the first fan module, such as turning off the power of fan module 1, and sets the other fan modules to full speed to simulate the scenario of the remaining fans running at full speed after fan module 1 is pulled out. When the speeds of all the other fan modules reach full speed, the power of the first fan module (such as fan module 1) is turned on, and its speed, voltage, and current values are detected in real time to determine whether the actual speed, fan speed regulation time, and fan current are within the specification defined range, and step S212 is entered.

[0141] Step S212: The main control unit records the voltage and current values during fan speed regulation and start-up in real time, and compares them with the rated values to ensure that the operating voltage and current of the fan module are within the rated value range, i.e., the actual power does not exceed the rated power value.

[0142] Step S213: In the case of starting a manual mode, this manual mode can be used for regular fan module testing or for fan module fault analysis and positioning. The speed is manually set, and the actual speed, fan speed regulation time, and fan current are checked for abnormalities, and step S214 is entered.

[0143] Step S214: The voltage and current of the fan module are detected in real time, and different fan speeds are manually set, and the voltage and current values of the fan module are checked.

[0144] Step S215: The main control unit saves the test data to the storage unit for subsequent data collection or viewing, and step S216 is entered.

[0145] Step S216: The main control unit determines whether to end the detection process. If yes, the detection process for the fan module is ended; otherwise, the method flow of step S203 and the method flow after step S203 are executed.

[0146] The process is ended.
