[0020] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.
[0021] Example 1
[0022] like Figure 1 and Figure 3 As shown, this embodiment proposes a handle board based on a domestic server, which is electrically connected to the BMC device of the server (i.e., the BMC of the server main control board), and the server also includes a CPU device, a CPLD device, an ADC device, a memory module and a fan, which are electrically connected to the BMC device respectively;
[0023] The handle board card includes a first handle board card, and an indicator light and / or a switch button module, as well as a digital tube display are provided on the TOP surface (i.e., the upper surface of the card);
[0024] A first connector is provided on the BOT surface (ie, the lower surface of the board) of the first handle board, and the first connector is electrically connected to the indicator light and / or switch button module, the BMC device and the digital tube display respectively.
[0025] It should be noted that Feiteng's S5000C-64 is selected as the CPU device, Feiteng's E2000S chip is selected as the BMC device, Ziguang Tongchuang's PGC7KD-6IMBG400 is selected as the CPLD device, and TI's ADS7828E is selected as the ADC device; the first handle board card and the second handle board card are respectively the boards in the left and right ears of the server. There is no restriction on whether the first handle board card and the second handle board card are located on the left or right side, and can be set according to actual needs. For example, in this embodiment, the first handle board card is the left handle board card, and the second handle board card is the right handle board card. The digital tube display is a three-digit digital tube, and different digital displays on the digital tube indicate the operating status of different devices in the server; in this embodiment, the first handle board is 54 mm long and 18.8 mm wide, the board level is 6 layers, and the first connector is a 32-pin slot, which is electrically connected to the indicator light and / or switch button module, the BMC device and the digital tube display through cables, and the indicator light and / or switch button module is electrically connected to the BMC device through the first connector, and the digital tube display is electrically connected to the BMC device through the first connector. The server provides 3.3VSB power supply for the first handle board and the second handle board.
[0026] In this embodiment, the indicator light and / or switch button module includes a power switch button and a corresponding first indicator light (power indicator light, including green and orange lights), second indicator lights (system fault indicator lights) corresponding to CPU devices, third indicator lights (memory fault indicator lights) corresponding to memory modules, fourth indicator lights (fan fault indicator lights) corresponding to fans, and a reset switch button corresponding to CPLD devices, and each indicator light and reset switch button are electrically connected to the first connector.
[0027] It should be noted that when the power switch button is turned on, the first indicator light is always green, and when the power switch button is turned off, the first indicator light is off.
[0028] When the power button is turned on, a power-on signal is transmitted to the BMC through the first connector. The BMC then transmits the signal to the CPLD. The CPLD detects the power-on signal and controls the server to start normal operation (that is, it powers on all components in the server, including the CPU, ADC, memory modules, fans, temperature sensors, network controllers, and hard disk controllers). The BMC then controls the first indicator to be solid green. When the power button is pressed and held (for example, for 5 seconds, which is the shutdown signal), a shutdown signal is transmitted to the BMC through the first connector. The BMC then transmits the signal to the CPLD. The CPLD detects the shutdown signal and shuts down the server (that is, it powers off all components in the server). The BMC then controls the first indicator to be solid green and then off.
[0029] A solid green second indicator indicates a normal server system. A solid red second indicator indicates a server system exception. After the server starts, if a server system exception occurs, the CPU sends an exception signal (named SYS_STATUS in this implementation) to the BMC, which then turns the second indicator solid red. After the server starts normally, the CPU does not send any signals to the BMC, indicating that the server system is operating normally. The BMC then turns the second indicator solid green.
[0030] If the third indicator is solid red, it indicates a memory module failure; if it is off, it indicates a normal memory module. After the server starts, if the memory module is functioning properly, it sends a normal signal to the BMC, which controls the third indicator to remain off. If the memory module is abnormal, it stops sending a signal to the BMC, and the BMC controls the third indicator to remain solid red.
[0031] A solid red fourth indicator light indicates a fan failure, while an off-state fourth indicator light indicates a normal fan condition. In this embodiment, the number of fans is not limited; for example, four fans are provided. After the server boots up, if all fans are operating normally, a normal signal (in this embodiment, a TACH signal) is sent to the BMC, which controls the fourth indicator light off. If at least one fan experiences an abnormality, an abnormality signal (an abnormal TACH signal) is sent to the BMC, which controls the fourth indicator light solid red.
[0032] After the server starts, the ADC sends all measured voltage values (such as 12V, 5V, and 3.3V) to the BMC through the I2C bus. The BMC compares the received voltage value with the set normal voltage value range. If it is not within this range, it indicates that a voltage is abnormal. The BMC controls the first indicator to be solid orange (if any voltage value is abnormal, the first indicator will be solid orange). When all voltages are within the range, the BMC controls the first indicator to be solid green.
[0033] After the server starts, the reset switch button is activated, sending a low-level signal through the first connection and the BMC device to the CPLD device. The CPLD device powers off all components in the server (including the CPU device, ADC device, memory module, fan, temperature sensor, network controller, and hard disk controller) for a period of time (such as tens of milliseconds) and then powers them on again.
[0034] In this embodiment, the server further includes a temperature sensor, a network controller, and a hard disk controller, each electrically connected to the BMC device. The indicator light and / or switch button module further includes a fifth indicator light (network indicator light) and a sixth indicator light (system disk fault indicator light) corresponding to the network controller and the hard disk controller, respectively.
[0035] It should be noted that the NST117 from Nanochip Micro is used as the temperature sensor, the WX1860AL2 from Netcom Technology is used as the network controller, and the X100 is used as the hard disk controller. A solid green fifth indicator light indicates a successful network connection, while an off-light fifth indicator light indicates a failed network connection. In this embodiment, two RJ45 network interfaces are provided. After the server is started, when all network interfaces are successfully connected, the network controller sends a signal (in this embodiment, designated as a LINK signal) to the BMC device. The BMC device controls the fifth indicator light to solid green, indicating a successful network connection. If the BMC device does not detect the LINK signal from the network controller, it indicates that at least one network interface has failed to connect, and the BMC device controls the fifth indicator light to off.
[0036] After the server starts, the sixth indicator lights up solid green, indicating that the system disk is operating normally. If it is off, it indicates an abnormal system disk status or a hard disk failure. When the system disk is operating normally, the hard disk controller sends a signal to the BMC, which controls the sixth indicator to light solid green. If the system disk is operating abnormally or a hard disk failure occurs, the hard disk controller does not send a signal to the BMC, which controls the sixth indicator to light off.
[0037] In this embodiment, a UID switch button and a corresponding ninth indicator light are further provided on the TOP surface of the first handle board.
[0038] It should be noted that the user uses the UID switch button to indicate whether the server has a fault, which is convenient for subsequent maintenance personnel to identify. When the UID switch button is on, the BMC device controls the seventh indicator light to be solid blue. When the UID switch button is off, the BMC device controls the seventh indicator light to be off. That is, maintenance personnel can determine whether the server has a fault based on the on and off of the seventh indicator light.
[0039] In this embodiment, the BOT surface of the first handle board is also provided with a signal conversion chip, a microcontroller chip and an LCD driver chip which are electrically connected in sequence. The signal conversion chip is electrically connected to the first connector, and the LCD driver chip is electrically connected to the digital tube display.
[0040] It should be noted that the CH340T chip from Jiangsu Qinheng is selected as the signal conversion chip, the STM32F051C8T6 chip from ST is selected as the microcontroller chip, and the HT1621B chip from Hetai is selected as the LCD driver chip.
[0041] When the server system fails, the voltage status detected by the ADC device is abnormal, the memory module fails, the fan fails, the temperature detected by the temperature sensor exceeds the preset temperature (after the server starts, the temperature sensor sends the measured temperature value to the BMC device and compares it with the maximum threshold set in the BMC device (80°C). If it exceeds this threshold, it indicates that the server is overheated), the network connection fails, or the system disk status is abnormal (or the hard disk fails), the BMC device controls the lighting of each segment on the digital tube display through the first connector, the signal conversion chip (the signal conversion chip that converts USB signals to UART signals), the microcontroller chip, and the LCD driver chip. To display the abnormal status of each server; specifically, when the server system fails, the voltage status detected by the ADC device is abnormal, the memory module fails, the fan fails, the temperature detected by the temperature sensor exceeds the preset temperature, the network connection fails, or the system disk status is abnormal (or the hard disk fails), the BMC device sends a signal to the corresponding indicator light through the first connector to control the status of each indicator light. At the same time, it also sends a signal to the signal conversion chip through the first connector. The signal conversion chip converts the received USB signal into a UART signal and sends it to the microcontroller chip. The microcontroller chip converts the UART signal into an SPI signal and sends it to the LCD driver chip. The LCD driver chip The chip then transmits the signal to the digital tube display to control the lighting of each segment of the digital tube display. In this embodiment, the digital tube display can be pre-set to display different numbers to indicate different faults. For example, when the server system fails, the digital tube display displays U00; when the voltage state detected by the ADC device is abnormal (wherein the voltage state of different values is abnormal, the digital tube display displays different numbers, such as when a 12V voltage abnormality is detected, the digital tube display displays U12, when a 5V voltage abnormality is detected, the digital tube display displays U05, and when a 3.3V voltage abnormality is detected, the digital tube display displays 3U3); when a memory module fails, the digital tube display displays U20; For each fan failure, the digital tube display shows a different number. For example, when fan 1 fails, the digital tube display shows U31, when fan 2 fails, the digital tube display shows U32, when fan 3 fails, the digital tube display shows U33, and when fan 4 fails, the digital tube display shows U34; when the temperature detected by the temperature sensor exceeds the preset temperature, the digital tube display shows U40; when the network connection of network interface 1 fails, the digital tube display shows U51, and when the network connection of network interface 2 fails, the digital tube display shows U52; when the system disk status is abnormal (or the hard disk fails), the digital tube display shows U60, and there is no restriction on the specific display.
[0042] In this embodiment, a fourth slot electrically connected to the microcontroller chip is further provided on the BOT surface of the first handle board.
[0043] It should be noted that the fourth slot is a 5-pin slot, which is used to burn the microcontroller chip. Users burn the firmware program into the microprocessor chip STM32 through the fourth slot.
[0044] like Figure 3 As shown, the first handlebar board is also provided with a crystal oscillator module, and the crystal oscillator module includes a crystal oscillator electrically connected to a signal conversion chip, a microcontroller chip and an LCD driver chip.
[0045] Figure 3 The lines on the left side of the BMC in the figure represent the signal interaction between the BMC and the first connector when the power switch button, reset switch button, and UID switch button are turned on or off, and the signal interaction between the BMC and the first connector when the CPU, ADC, memory module, fan, temperature sensor, network controller, and hard disk controller send and / or do not send signals to the BMC. Figure 3 The lines below the BMC represent the signals sent by the CPU, ADC, memory modules, fans, temperature sensors, network controllers, hard disk controllers, and CPLD to the BMC, as well as the names of the signals.

[0047] like Figure 2-Figure 3 As shown, based on Example 1, Example 2 further discloses that the handle board card also includes a second handle board card, and the TOP surface of the second handle board card is provided with a first slot, a second slot and a third slot, and the BOT surface of the second handle board card is provided with a second connector, and the first slot, the second slot and the third slot are all electrically connected to the second connector, and the second connector is electrically connected to the BMC device.
[0048] It should be noted that the first slot and the second slot are both USB standard interface slots, compatible with USB2.0 and USB3.0 interfaces. Figure 3 The first slot is represented by the USB1 slot, the second slot is represented by the USB2 slot, and the third slot is a VGA slot, which is a standard VGA interface. The first, second, and third slots can be connected to external devices; the second connector is 32 2mm*0.5mm solder pads, and each solder pad is provided with a cable electrically connected to the BMC device. The first, second, and third slots are electrically connected to each solder pad through the traces on the board.
[0049] The components on the TOP surface or the BOT surface of each handle board can be mounted on the handle board by welding.
[0050] The above-described embodiments merely represent several implementation methods of the present application.
