[0075] Step S360: According to the BIT information collection and reporting instruction, the BMC collects the BIT information of the CPU module and sends it to the CPU module through the serial port, and then reports it to the test computer through the network port to realize the BIT information collection of the CPU module.

[0076] BMC collects BIT information of each module and sends it to the CPU module through the serial port, and then reports the serial port data to the test computer through the network port to realize the BIT information collection of each module.

[0104] After receiving the electronic disk software and hardware destruction instruction, the BMC in the fourth operation unit will operate the register of the CPLD through IIC communication to realize the electronic disk software and hardware destruction of each module.

[0105] Please see Figures 1 to 7 This embodiment provides a method and system for remotely controlling a BMC to switch between multiple module working modes. The following is an explanation based on a specific embodiment:

[0106] The CMD command code is sent externally through the network and sent to the main CPU module through the network TCP / UDP. The main CPU module parses the received command to determine whether it is an instruction code such as working mode switching, GPU graphics card display switch, GPGPU switch, BIT information collection or electronic disk destruction.

[0107] After the main processing module receives the mode switching instruction, the main CPU module sends the BMC the mode to be switched to via RS232. The BMC 2 C instruction operation writes multiple module CPLD registers to perform power on / off operations on multiple modules. CPLD then uses I 2 C replies to the main processing module why the working mode is selected, thereby realizing the switching of multiple working modes.

[0108] After the main processing module receives the GPU display switch command (the GPU of one or more modules can be specified), the main CPU module sends the command to the BMC via RS232 to indicate which module's GPU display needs to be turned off or on. The BMC then sends the command to the BMC via I 2 C instruction operation writes multiple module CPLD registers to switch the display of the GPU graphics card of the specified module, and the CPLD then uses I 2 C replies to the main processing module which modules' GPU displays are currently closed or opened, so as to open or close the GPU display of a specified module or multiple modules. If the closed GPU graphics card is switched on, the specified CPU module will be automatically restarted.

[0109] After the main processing module receives the GPU display switch command (the GPGPU of one or more modules can be specified), the main CPU module sends the command to the BMC via RS232 to indicate which module's GPGPU AI card needs to be turned off or on. The BMC then sends the command to the BMC via I 2C instruction operation writes multiple module CPLD registers to switch the GPGPU AI graphics card of the specified module, and the CPLD then uses I 2 C replies to the main processing module which modules' GPGPU AI cards are currently closed or opened, so as to open or close the GPGPU AI cards of a specified module or multiple modules. If the closed GPGPU AI card is switched on, the specified CPU module will be automatically restarted.

[0110] After the main processing module receives the BIT information collection and reporting instruction, the main CPU module sends the BIT information of which module to be collected to the BMC via RS232. The BMC sends the collected BIT information of the corresponding module back to the main CPU module via RS232. After the main CPU module receives the RS232 information data sent by the BMC, it forwards it to the PC debugging computer through the network port via TCP / UDP, thereby realizing the collection of BIT information of multiple modules.

[0111] After the main processing module receives the soft and hard destruction instructions of the electronic disk, the main CPU module sends to the BMC through RS232 whether to perform soft destruction or hard destruction. The soft destruction BMC writes to multiple module CPLD registers through I2C instructions, and the CPLD then operates the corresponding soft destruction signal of the electronic disk to realize the soft destruction function (formatting) of the electronic disk. After formatting, the disk can still install the system normally; the hard destruction BMC writes to multiple module CPLD registers through I2C instructions, and the CPLD then operates the corresponding hard destruction signal of the electronic disk to realize the hard destruction function of the electronic disk (electronic damage is irreparable).

[0112] The present embodiment provides a method and system for remotely controlling BMC to switch multiple module working modes. Compared with the prior art, the method and system can realize the switching of CPU module working mode and the acquisition of BIT information by receiving data packets transmitted through the network interface; converting the data packets into serial port data by software processing; and sending the converted serial port data to BMC.
