[0002] BMC (Baseboard Management Controller) is installed on the mainboard of the server to monitor and manage the hardware components of the server and the system operation status. Regarding the design of the BMC module, there are currently the following solutions: the first is to design a separate BMC module for each server; the second is to design the BMC function directly on the mainboard; the third is to design a universal BMC module for use with multiple mainboards.
