[0031] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0032] It should be noted that, in the description of the present application, the terms "comprise", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or device.

[0033] In order for those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0034] In combination with the specific application environment architecture or specific hardware architecture on which the execution of the pilot lamp method of the data center switch depends, the specific application environment architecture or specific hardware architecture is described here.

[0035] With the impetus of the digital era, the data center, as the core infrastructure of the digital economy, is rapidly expanding at an unprecedented speed. With the popularity of cloud computing, big data analysis, and artificial intelligence applications, there is a high demand for data processing and storage capabilities. Data center switches, as the key devices connecting servers, storage devices, and implementing data transmission and exchange, have also seen a surge in demand. There are multiple indicator lights in data center switches, and the traditional system lighting scheme for these indicator lights gradually exposes many problems. For traditional BMC management machines, the traditional lighting can still meet the demand, but for CPU management machines, BMC and CPU parallel management machines, the traditional lighting scheme cannot combine the state information of BMC and CPU for lighting. In addition, if the system lights are needed to represent system startup, system working, power failure, temperature failure, and other information, the traditional system lighting scheme cannot determine the priority of the above information, resulting in the inability to display the most important information through the system lights in time. The traditional lighting scheme cannot meet the flexible lighting needs, thereby increasing the research and development and operation and maintenance costs.

[0036] Based on the above, the embodiment of the present application provides a lighting method for a data center switch. In order to meet the complex application scenarios, the device system light management is divided into a CPLD (CMOS Programmable Logic Device, Complementary Metal Oxide Semiconductor Programmable Logic Device) / BMC / CPU parallel lighting interface. At the same time, in order to meet the factory production needs, a test mode is added. The lighting interface supports parallel access, and the lighting behavior supports priority operation. High-priority faults can cover low-priority fault lights. The lighting scheme provides a unified configuration interface for the upper software, facilitates software unified processing, reduces software processing complexity, thereby reducing development difficulty and risk, reducing operation cost, and achieving the purpose of improving economic benefit. It can light according to the priority in the case of BMC and CPU parallel management machines, and meet various lighting needs.

[0037] According to the embodiment of the present application, a lighting method for a data center switch is provided. 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 group 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 a different order from here.

[0038] In this embodiment, a lighting method for a data center switch is provided, Figure 1 is a flowchart of the lighting method for a data center switch according to the embodiment of the present application, as Figure 1 shown, the flow includes the following steps:

[0039] In step S101, a first state code and a second state code are acquired, wherein the first state code is used to determine the start state of the first management and control device, and the second state code is used to determine the start state of the second management and control device.

[0040] Specifically, the embodiment designs a lighting system of a data center switch based on a programmable logic device CPLD, as shown in the figure. Figure 2 As shown in the figure, the system includes an indicator light management (LED Ctrl) module, the indicator light management module includes a system indicator light management (sys_LED_ctrl) unit, and the LED (Light Emitting Diode) is a light emitting diode. In addition, the system also includes a central processing unit and a server remote management controller, the central processing unit is provided with an LPC controller (Low Pin Count Controller), and the server remote management controller is provided with an I2C controller (Inter-Integrated Circuit Controller). Correspondingly, the programmable logic device is provided with an LPC_slave_interface module, an I2C_slave_interface module, a register interface 1 and a register interface 2. The LPC_slave_interface interface module is used to parse the LPC read-write protocol and convert it into a read-write enable signal, an address signal, a write data signal and a read data signal. The I2C_slave_interface interface module is used to parse the I2C read-write protocol and convert it into a read-write enable signal, an address signal, a write data signal and a read data signal; the register interface is used to complete the register read-write function and address space division. The indicator light management module is used to complete the CPLD autonomous lighting of the system indicator light, the BMC and CPU interface lighting. The system indicator light management unit is provided with a central processing unit start state (CPU_boot_state) submodule and a server remote management controller start state (BMC_boot_state) submodule.

[0041] The first management and control device is, for example, a CPU, and the second management and control device is, for example, a BMC. The indicator light management module acquires the first state code and the second state code. The central processing unit start state submodule can determine the start state of the first management and control device according to the first state code, for example, whether the first management and control device is started, whether the first management and control device is a master device or a standby device, the start time of the first management and control device, whether the first management and control device is timed out and not started, etc. The server remote management controller start state submodule can determine the start state of the second management and control device according to the second state code, for example, whether the second management and control device is in place, whether the second management and control device is started, the start time of the second management and control device, whether the second management and control device is timed out and not started, etc.

[0042] Step S102, generating an initial lighting code according to the first state code and the second state code.

[0043] Specifically, according to the first state code and the second state code, the starting state of the first control device and the second control device is determined, and the initial lighting code is generated according to the determination result. For example, the initial lighting code is the system lighting code controlled by the CPLD, and the system lighting code is composed of CPLD_LED_code and CPLD_LED_blink. The CPLD_LED_code controls the lighting color of the indicator light, and the CPLD_LED_blink controls whether the indicator light supports flashing.

[0044] Step S103, generating an intermediate lighting code according to the control enable signal and the initial lighting code, wherein the control enable signal is used to determine whether to enable the control function of the first control device and the second control device.

[0045] Specifically, the control enable signal is, for example, BMC_sys_ctrl_reg (server remote management controller system control register) and CPU_sys_ctrl_reg (central processing unit system control register). The control enable signal is used to determine whether to enable the control function of the first control device and the second control device.

[0046] In order to meet the complex application scenarios, the device system light management is split into CPLD / BMC / CPU parallel lighting interface in this embodiment. The indicator light management module realizes three-interface mixed lighting according to the control enable signal and the initial lighting code, generates an intermediate lighting code according to the control enable signal and the initial lighting code, and manages whether the system indicator light is lit, the lighting color, and whether it flashes through the intermediate lighting code.

[0047] Step S104, obtaining a target lighting code according to the system lighting control bit signal and the intermediate lighting code, and lighting the indicator light of the switch according to the target lighting code, wherein the system lighting control bit signal is used to determine the lighting state of the indicator light.

[0048] Specifically, in order to meet the factory production needs and increase the test mode lighting, there are two modes of test mode lighting and normal mode lighting for the indicator light of the switch. The normal mode lighting uses the intermediate lighting code, and the test mode lighting uses the test register lighting code in the system lighting control bit signal (sys_LED_ctrl_reg).

[0049] The system lighting control bit signal is used to determine the lighting state of the indicator light, for example, the lighting state includes normal mode lighting or test mode lighting, whether the indicator light flashes, the lighting color of the indicator light, automatic exit test mode lighting after timeout, timeout time, and the like. According to the system lighting control bit signal and the intermediate lighting code, the target lighting code is obtained, for example, according to the system lighting control bit signal, it is determined that the current is normal mode lighting, and according to the intermediate lighting code, the target lighting code is obtained; according to the system lighting control bit signal, it is determined that the current is test mode lighting, and according to the test register lighting code in the system lighting control bit signal, the target lighting code is obtained. According to the target lighting code, the indicator light of the switch is lit, which indicator light is lit, the lighting color of the indicator light is set, and whether the indicator light flashes.

[0050] In addition, the lighting behavior of the embodiment can support priority operation, and a high-priority fault can cover a low-priority fault light. The lighting method of the embodiment can be applied to other use environments in addition to the switch field, for example, a system lighting scheme in the communication field.

[0051] The lighting method of the data center switch provided by the embodiment generates an initial lighting code according to a first state code and a second state code; determines whether to enable the control function of the management and control device according to a control enabling signal, and generates an intermediate lighting code in combination with the initial lighting code; determines the lighting state of the indicator light according to a system lighting control bit signal, obtains a target lighting code in combination with the intermediate lighting code, and lights the indicator light of the switch according to the target lighting code. When the server remote management controller and the central processing unit are managed in parallel, the start state is determined according to the respective state codes, the intermediate lighting code is generated in combination with the start state and the control function of the management and control device, and the state of each management and control device is considered, the accuracy of system lighting is improved, the lighting state demand is determined through the system lighting control bit signal, the target lighting code is obtained in combination with the lighting state demand and the intermediate lighting code, and the lighting is performed, the reliability and stability of system lighting are enhanced while meeting the lighting demand. The problem that the lighting scheme of the data center switch cannot meet the lighting demand of the parallel management of the server remote management controller and the central processing unit is solved, and the research and development and operation and maintenance costs are increased.

[0052] As an optional embodiment, the first state code and the second state code are obtained, including:

[0053] The first start completion signal, the master-slave identification signal, and the first start time signal of the first management and control device are obtained;

[0054] The in-place signal, the second start completion signal, and the second start time signal of the second management and control device are obtained;

[0055] According to the first start completion signal, the main / backup identification signal and the first start time signal, a first state code is generated;

[0056] According to the in-place signal, the second start completion signal and the second start time signal, a second state code is generated.

[0057] Specifically, the first management and control device is, for example, a CPU, and the second management and control device is, for example, a BMC. The first start completion signal, the main / backup identification signal and the first start time signal of the first management and control device are acquired. The first start completion signal is a CPU_boot_ok signal, the main / backup identification signal is a CPU_boot_sel signal, and the first start time signal is a CPU_boot_time signal. The CPU_boot_state submodule mainly judges the CPU start state based on CPU_boot_ok, CPU_boot_sel and CPU_boot_time, and then generates a CPU state code as the first state code. CPU_boot_ok identifies whether the CPU has completed starting; CPU_boot_sel mainly identifies the CPU main / backup, 0 indicating the main and 1 indicating the backup; and CPU_boot_time mainly identifies the CPU start time.

[0058] According to the first start completion signal, the main / backup identification signal and the first start time signal, a first state code is generated, for example, the first state code is a CPU state code CPU_boot_code. CPU_boot_code=3`b000 indicates that the system is starting in the main mode, CPU_boot_code=3`b001 indicates that the system is starting in the backup mode, CPU_boot_code=3`b010 indicates that the backup has not completed starting in the timeout mode, CPU_boot_code=3`b100 indicates that the system has completed starting in the main mode, and CPU_boot_code=3`b101 indicates that the system has completed starting in the backup mode.

[0059] The in-place signal, the second start completion signal and the second start time signal of the second management and control device are acquired, the in-place signal is a BMC_present_n signal, the second start completion signal is a BMC_boot_ok signal, and the second start time signal is a BMC_boot_time signal. The BMC_boot_state submodule mainly judges the BMC start state based on the BMC_present_n, the BMC_boot_ok and the BMC_boot_time, and then generates a BMC state code as the second state code. The BMC_present_n indicates whether the BMC card is in place, 0 indicating that the BMC card is in place, and 1 indicating that the BMC card is not in place; the BMC_boot_ok indicates whether the BMC is started, 0 indicating that the BMC is not started, and 1 indicating that the BMC is started; and the BMC_boot_time indicates the BMC start time, and whether the BMC is started or not can be determined.

[0060] According to the in-place signal, the second start completion signal and the second start time signal, the second state code is generated, for example, the second state code is a BMC state code BMC_boot_code, BMC_boot_code = 2`b00 indicates that the BMC is being started; BMC_boot_code = 2`b10 indicates that the BMC is not started in time; and BMC_boot_code = 2`b11 indicates that the BMC is started.

[0061] In the embodiment of the application, the start state of the first management and control device is judged according to the first start completion signal, the master-slave identification signal and the first start time signal of the first management and control device; the start state of the second management and control device is judged according to the in-place signal, the second start completion signal and the second start time signal of the second management and control device, and the first state code and the second state code are generated according to the judgment results. The light-on code is generated based on the first state code and the second state code, which improves the accuracy of system light-on, and enhances the reliability and stability of system light-on.

[0062] As an optional embodiment, the first state code is generated according to the first start completion signal, the master-slave identification signal and the first start time signal, including:

[0063] The first start completion signal is compared with a first value, the master-slave identification signal is compared with a second value, and the first start time signal is compared with a third value, to obtain a first comparison result;

[0064] A first target code value corresponding to the first comparison result is determined;

[0065] The first state code is obtained according to the first target code value.

[0066] Specifically, the first boot completion signal is the CPU_boot_ok signal, the primary / standby identification signal is the CPU_boot_sel signal, and the first boot time signal is the CPU_boot_time signal.

[0067] The first value is, for example, 1'b1, where 1'b1 represents binary 1, 1'b indicates only one binary bit, and 2'b indicates two binary bits. The following value represents the data. The second value is, for example, 1'b0. The third value is, for example, 6 minutes. The first boot completion signal is compared with the first value, the primary / standby identifier signal is compared with the second value, and the first boot time signal is compared with the third value to obtain the first comparison result. The first comparison result is, for example, CPU_boot_ok == 1'b1 and CPU_boot_sel == 1'b0, CPU_boot_ok is not equal to 1'b1, CPU_boot_sel == 1'b0, CPU_boot_time < 6min, etc.

[0068] Determine the first target encoding value corresponding to the first comparison result. For example: if the first comparison result is CPU_boot_ok == 1'b1 and CPU_boot_sel == 1'b0, the first target encoding value is 3'b100; if the first comparison result is CPU_boot_ok not equal to 1'b1, CPU_boot_sel == 1'b0, and CPU_boot_time < 6min, the first target encoding value is 3'b000; if the first comparison result is CPU_boot_ok not equal to 1'b1, CPU_boot_sel == 1'b1, and CPU_boot_time < 6min, the first target encoding value is 3'b001.

[0069] The first state code is obtained based on the first target code value. For example, the first target code value is directly used as the first state code CPU_boot_code; or the first target code value is concatenated with a pre-agreed code value, and the concatenated code value is used as the first state code CPU_boot_code.

[0070] The above process is as follows Figure 3Idle; judging whether CPU_boot_ok == 1'b1 is satisfied, in the case of satisfying CPU_boot_ok == 1'b1, checking whether the CPU is a master device or a standby device, if CPU_boot_sel == 1'b0 and CPU_boot_code == 3'b100 are satisfied, if CPU_boot_sel == 1'b0 and CPU_boot_code == 3'b101 are not satisfied. In the case of not satisfying CPU_boot_ok == 1'b1, if CPU_boot_sel == 1'b0 and CPU_boot_time < 6min, CPU_boot_code == 3'b000; if CPU_boot_sel == 1'b1 and CPU_boot_time < 6min, CPU_boot_code == 3'b001; if CPU_boot_sel == 1'b1 and CPU_boot_time > 6min, CPU_boot_code == 3'b010.

[0071] As an optional embodiment, the second state code is generated according to the in-place signal, the second boot completion signal and the second boot time signal, and includes:

[0072] The in-place signal is compared with a fourth value, the second boot completion signal is compared with a fifth value, and the second boot time signal is compared with a sixth value to obtain a second comparison result.

[0073] A second target code value corresponding to the second comparison result is determined.

[0074] The second state code is obtained according to the second target code value.

[0075] Specifically, the in-place signal is a BMC_present_n signal, the second boot completion signal is a BMC_boot_ok signal, and the second boot time signal is a BMC_boot_time signal.

[0076] The fourth value is, for example, 1'b0. The fifth value is, for example, 1'b1. The third value is, for example, 6 minutes. The in-place signal is compared with the fourth value, the second boot completion signal is compared with the fifth value, and the second boot time signal is compared with the sixth value to obtain a second comparison result. The second comparison result is, for example, BMC_present_n == 1'b0, BMC_boot_ok == 1'b1, BMC_present_n == 1'b0, BMC_boot_ok!= 1'b1, BMC_boot_time > 6min, and BMC_present_n!= 1'b0.

[0077] determining a second target encoding value corresponding to the second comparison result, for example, the second comparison result is BMC_present_n not equal to 1'b0, and the second target encoding value is 2'b11; the second comparison result is BMC_present_n == 1'b0, BMC_boot_ok == 1'b1, and the second target encoding value is 2'b11; the second comparison result is BMC_present_n == 1'b0, BMC_boot_ok not equal to 1'b1, and BMC_boot_time > 6min 2'b10.

[0078] According to the second target encoding value, a second state encoding is obtained, for example, the second target encoding value is directly taken as the second state encoding BMC_boot_code; the second target encoding value is spliced with a pre-agreed encoding value, and the spliced encoding value is taken as the second state encoding BMC_boot_code.

[0079] The above process is shown in Figure 4 The idle state is determined whether BMC_present_n == 1'b0 is satisfied, if BMC_present_n == 1'b0 is not satisfied, BMC_boot_code == 2'b11; if BMC_present_n == 1'b0 is satisfied, the BMC start state is checked; whether BMC_boot_ok == 1'b1 is satisfied is determined, if BMC_boot_ok == 1'b1 is satisfied, BMC_boot_code == 2'b11; if BMC_boot_ok == 1'b1 is not satisfied, the BMC timeout time is checked, if BMC_boot_time > 6min, BMC_boot_code == 2'b10, if BMC_boot_time ≤ 6min, BMC_boot_code == 2'b00.

[0080] As an optional embodiment, according to the first state encoding and the second state encoding, an initial lighting encoding is generated, including:

[0081] The start state encoding is generated in combination with the first state encoding and the second state encoding;

[0082] The value of the start state encoding is matched with the encoding value in the preset encoding set to obtain a first matching result, and a third target encoding value equal to the value of the start state encoding is determined according to the first matching result;

[0083] According to the first preset numerical value corresponding to the third target encoding value, a first color confirmation encoding is generated, wherein the first color confirmation encoding is used to determine the color of the indicator light;

[0084] generate a first flicker confirmation code according to the third target code value corresponding to the second preset value, wherein the first flicker confirmation code is used to determine whether the indicator light flickers or not;

[0085] generate an initial lighting code according to the first color confirmation code and the first flicker confirmation code.

[0086] Specifically, the system indicator light management unit CPLD autonomous lighting interface mainly judges the BMC and CPU startup state based on BMC_boot_code and CPU_boot_code, and then generates a system lighting code controlled by the CPLD autonomously.

[0087] generate a startup state code in combination with the first state code and the second state code, for example: the first state code is CPU_boot_code, the second state code is BMC_boot_code, in combination with (CPU_boot_code, BMC_boot_code), the first state code is 3’b001, the second state code is 2’b00, and the startup state code is generated as 5'b00_001; the first state code is 3’b101, the second state code is 2’b00, and the startup state code is generated as 5'b00_101; the first state code is 3’b000, the second state code is 2’b10, and the startup state code is generated as 5'b10_000.

[0088] The preset code set is, for example: 5'b00_000, 5'b00_100, 5'b11_000, 5'b00_001, 5'b00_101, 5'b11_001, 5'b10_000, 5'b10_001, 5'b00010, 5'b10100, 5'b10101, 5'b11101, 5'b10010, 5'b11010, 5'b11100.

[0107] The eighth numerical value is, for example, 1’b1. The second sub-control signal is compared with the eighth numerical value to obtain a fourth comparison result, for example, BMC_sys_ctrl_reg[7] == 1’b1 or BMC_sys_ctrl_reg[7] not equal to 1’b1.

[0108] According to the third comparison result and the fourth comparison result, a fourth target code value is obtained from the first sub-control signal, the second sub-control signal, the first color confirmation code, and the first flicker confirmation code, for example: the third comparison result is CPU_sys_ctrl_reg[7] == 1'b1, and the fourth comparison result is BMC_sys_ctrl_reg[7] == 1'b1, and the fourth target code value includes CPLD_LED_code[2:0], CPU_sys_ctrl_reg[2:0], BMC_sys_ctrl_reg[2:0], and CPLD_LED_blink; or the third comparison result is CPU_sys_ctrl_reg[7]!= 1'b1, and the fourth comparison result is BMC_sys_ctrl_reg[7]!= 1'b1, and the fourth target code value includes CPLD_LED_code[2:0] and CPLD_LED_blink.

[0119] As an optional embodiment, the intermediate light-up code includes a second color confirmation code and a second flashing confirmation code. Based on the system light-up control bit signal and the intermediate light-up code, the target light-up code is obtained, including:

[0120] the encoding value of the fourth data bit in the system light control bit signal as a first reference encoding value, the encoding value of the fifth data bit as a second reference encoding value, and the encoding value of the sixth data bit as a third reference encoding value;

[0121] In a case where the first reference encoding value is not equal to the ninth numerical value, a target light encoding is generated according to a third preset numerical value, a second flicker confirmation encoding, and the encoding value of the seventh data bit in the second color confirmation encoding;

[0122] In a case where the first reference encoding value is equal to the ninth numerical value, if the second reference encoding value is not equal to the tenth numerical value, a target light encoding is generated according to a fourth preset numerical value, the encoding value of the seventh data bit in the system light control bit signal, and the encoding value of the eighth data bit in the system light control bit signal;

[0123] If the second reference encoding value is equal to the tenth numerical value and the third reference encoding value is less than the eleventh numerical value, a target light encoding is generated according to a third preset numerical value, the encoding value of the seventh data bit in the system light control bit signal, and the encoding value of the eighth data bit in the system light control bit signal.

[0124] Specifically, the system light control bit signal is, for example, sys_LED_ctrl_reg, wherein sys_LED_ctrl_reg[7] represents a light module, 0 represents a normal mode light, and 1 represents a test mode light; sys_LED_ctrl_reg[6] represents a flicker control, 0 represents a constant light, and 1 represents a flicker; sys_LED_ctrl_reg[5] represents a test mode timeout automatic exit enable, 0 represents a timeout automatic exit function disabled, and 1 represents a timeout automatic exit function enabled, sys_LED_ctrl_reg[4:3] represents a timeout time, 00 represents 1 minute, 01 represents 5 minutes, 10 represents 10 minutes, and 11 represents 15 minutes; and sys_LED_ctrl_reg[2:0] represents a light color control, 001 represents green, 010 represents yellow, and 100 represents red.

[0125] The fourth data bit is, for example, 7. The fifth data bit is, for example, 5. The sixth data bit is, for example, [4:3]. The encoding value of the fourth data bit in the system light control bit signal is taken as a first reference encoding value sys_LED_ctrl_reg[7], the encoding value of the fifth data bit is taken as a second reference encoding value sys_LED_ctrl_reg[5], and the encoding value of the sixth data bit is taken as a third reference encoding value sys_LED_ctrl_reg[4:3].

[0126] The system indicator light management unit outputs a comprehensive lighting code as a target lighting code (LED_code) based on sys_LED_ctrl_reg, sys_LED_code and sys_LED_blink during the test mode lighting and normal mode lighting process. The LED_code represents a mixed lighting code. The normal mode uses a three-interface mixed lighting code, and the test mode uses a test register lighting code.

[0127] In combination Figure 7 The ninth value is, for example, 1'b1. The tenth value is, for example, 1'b1. The eleventh value is, for example, 5 seconds. The third preset value is, for example, 1'b0. The fourth preset value is, for example, 1'b1. The seventh data bit is, for example, 6. The eighth data bit is, for example, [2:0].

[0128] In the case where sys_LED_ctrl_reg[7] is not equal to 1'b1, the target lighting code (LED_code) is generated according to 1'b0, sys_LED_blink and sys_LED_code[2:0], that is, LED_code == {1'b0,sys_LED_blink,sys_LED_code[2:0]}.

[0129] In the case where sys_LED_ctrl_reg[7] is equal to 1'b1, if sys_LED_ctrl_reg[5] is not equal to 1'b1, the target lighting code is generated according to the fourth preset value 1'b1, sys_LED_ctrl_reg[6] and sys_LED_ctrl_reg[2:0], that is, LED_code == {1'b1,sys_LED_ctrl_reg[6],sys_LED_ctrl_reg[2:0]}.

[0130] If sys_LED_ctrl_reg[5] is equal to 1'b1 and sys_LED_ctrl_reg[4:3] is less than 5 seconds, the target lighting code is generated according to 1'b1, sys_LED_ctrl_reg[6] and sys_LED_ctrl_reg[2:0], that is, LED_code == {1'b1,sys_LED_ctrl_reg[6],sys_LED_ctrl_reg[2:0]}. Whether sys_LED_ctrl_reg[4:3] is less than 5 seconds can be determined by a 5-second timing counter.

[0131] In addition, if time5s_cnt>sys_LED_ctrl_reg[4:3] and sys_LED_ctrl_reg[5]<=1'b0, the step of generating the target lighting code in this embodiment is re-executed.

[0132] In the embodiment of the present application, the accurate switching of normal mode lighting and test mode lighting is realized through the system lighting control bit signal, and the flexible configuration of flickering and color is supported. The test mode supports automatic exit and multiple time length options to avoid long-term occupation of lighting resources. The scene standardized target lighting code generation logic guarantees the consistency of the indicator light output. The accurate determination of timeout is combined with the timing counter to improve the reliability of mode switching and the ease of use of the system.

[0133] As an optional embodiment, the indicator light of the switch is lit according to the target lighting code, which comprises:

[0134] According to the preset lighting priority, the value of the target lighting code is matched with a preset number of reference code values to obtain a second matching result.

[0135] According to the second matching result, a fifth target code value equal to the value of the target lighting code is determined.

[0136] The target lighting code is adjusted according to the fifth target code value, and the indicator light of the switch is lit according to the adjusted target lighting code.

[0137] Specifically, the preset lighting priority is, for example, as shown in Figure 8 The lighting priority is green light flickering, yellow light flickering, red light flickering, green light, yellow light, red light, test mode lighting flickering, test mode lighting constant, and lighting state retention.

[0138] The preset number represents a plurality, and no specific number is limited here. The preset number of reference code values are, for example, 5'b01001 for green flickering, 5'b0101x for yellow flickering, 5'b011xx for red flickering, 5'b00001 for green constant, 5'b0001x for yellow constant, 5'b001xx for red constant, 5'b11xxx for test mode flickering control, and 5'b10xxx for test mode constant control.

[0139] The color priority lighting of the system indicator light management unit is mainly based on the actual lighting code generated by LED_code.

[0140] According to the preset lighting priority, the value of the target lighting code (LED_code) is matched with a preset number of reference code values to obtain a second matching result, for example, as shown in Figure 8As shown, first, it is judged whether the LED_code is equal to 5'b01001, then whether the LED_code is equal to 5'b0101x, then whether the LED_code is equal to 5'b011xx, and finally whether the LED_code is equal to 5'b10xxx, to obtain a second matching result. The second matching result is, for example, LED_code == 5'b01001, LED_code == 5'b0101x, …, LED_code == 5'b10xxx.

[0141] According to the second matching result, a fifth target code value equal to the value of the target lighting code is determined, for example, the second matching result is LED_code == 5'b01001, and the fifth target code value is 5'b01001; the second matching result is LED_code == 5'b0101x, and the fifth target code value is 5'b0101x.

[0142] The lighting code corresponding to the fifth target code value is, for example, the fifth target code value is 5'b01001, and the corresponding lighting code is 4'd5; the fifth target code value is 5'b011xx, and the corresponding lighting code is 4'd7; the fifth target code value is 5'b0001x, and the corresponding lighting code is 4'd2; and the fifth target code value is 5'b10xxx, and the corresponding lighting code is 4'd5 / 6 / 7.

[0143] According to the lighting code corresponding to the fifth target code value, the target lighting code is adjusted to obtain an adjusted target lighting code, for example, the adjusted target lighting code is LED_code == 4'd5; the adjusted target lighting code is LED_code == 4'd1; and the adjusted target lighting code is LED_code == 4'd5 / 6 / 7, and the specific process is as shown in Figure 8 Therefore, the detailed description is omitted here. The indicator light of the switch is lit according to the adjusted target lighting code.

[0144] In the embodiments of the present application, the accurate matching of the lighting code is realized according to the preset priority, which guarantees the priority display of the fault or critical state. The mapping logic of the standardized reference code and the hardware lighting code avoids the conflict of state indication. The encoding matching process is simplified, which helps the operation and maintenance to quickly identify the device state and unify the lighting control rules.

[0145] As an optional embodiment, the specific process of the above-mentioned steps of "obtaining the first startup completion signal, the master-slave identification signal and the first startup time signal of the first controlled device" and "obtaining the in-place signal, the second startup completion signal and the second startup time signal of the second controlled device" can include steps A1 to A6.

[0146] In this embodiment, the first boot completion signal is the CPU_boot_ok signal, the primary / standby identifier signal is the CPU_boot_sel signal, and the first boot time signal is the CPU_boot_time signal. The present signal is the BMC_present_n signal, the second boot completion signal is the BMC_boot_ok signal, and the second boot time signal is the BMC_boot_time signal.

[0147] Step A1: Obtain the CPU_boot_ok signal.

[0148] Specifically, after the CPU completes boot (initializing the core, cache, and bus), the CPU datasheet locates the corresponding internal CPU register, such as the MSR or SCR register, and reads the CPU_boot_ok signal from this register. Alternatively, the CPU_boot_ok signal can be read from the BIOS POST log.

[0149] Step A2: Obtain the CPU_boot_sel signal.

[0150] Specifically, the CPU_boot_sel signal is usually a hardware strap signal or a BIOS configuration parameter. It can be obtained during boot by checking the hardware configuration, for example, by locating the DIP switch / jump corresponding to CPU Boot Selection and observing the current position (0 = primary, 1 = secondary). The CPU_boot_sel signal is generated accordingly. The CPU_boot_sel signal can also be read at the OS level.

[0151] Step A3: Obtain the CPU_boot_time signal.

[0152] Specifically, the timing start point is set to CPU power-on (when VCC core voltage is stable), and the timing end point is set to CPU_boot_ok being set. The total timing duration is obtained through timing measurement or log timing, and then the CPU_boot_time signal is generated.

[0153] Step A4: Obtain the BMC_present_n signal.

[0154] Specifically, the BMC_present_n signal is an active low signal. When the BMC card is physically present, the pin is at a low level. The BMC_present_n signal is generated by obtaining the hardware level or verifying whether the BMC is present based on the BMC communication status.

[0155] Step A5: Obtain the BMC_boot_ok signal.

[0156] Specifically, after the BMC startup is completed (firmware is loaded and the management interface is initialized), the BMC updates its state register, and the BMC_boot_ok signal is obtained by reading the state register of the BMC.

[0157] Step A6, the BMC_boot_time signal is obtained.

[0158] Specifically, the starting point of the timing is set as the power-on of the BMC (12V power supply is stable), the ending point of the timing is set as the setting of BMC_boot_ok, the total timing duration is obtained through the BMC log, timing measurement and API query, and the BMC_boot_time signal is generated.

[0159] In addition, the hardware configuration type signal (such as CPU_boot_sel and BMC_present_n) can be obtained by checking the jumper or physical connection first, and then verified through the BIOS / BMC interface; the state identification type signal (such as CPU_boot_ok and BMC_boot_ok) can be obtained through the IPMI / UEFI command first, and then verified through the hardware level; the time type signal (such as CPU_boot_time and BMC_boot_time) can be measured accurately through the timer or estimated through the log. If it is necessary to obtain signals in batches or automatically obtain signals, scripts can be developed based on the IPMI / Redfish interface to avoid manual operation.

[0160] In the embodiment of the application, the CPU and BMC startup state are accurately perceived, and a standardized state code is output. The startup fault (such as BMC absence and CPU startup timeout) is quickly located, and the troubleshooting cycle is shortened. The automatic switching of the main and standby CPUs, abnormal alarm and other automatic operations are supported. The hardware monitoring precision of the server is improved, and the stability and reliability in the startup stage are guaranteed.
