the sub-BMC module, the double-BMC signal switching module and the VGA display output control module are designed on the same PCB mainboard, and the display output of the mainboard is realized by the sub-BMC module through a channel of the double-BMC signal switching module by default; the main BMC module is interconnected and communicated with the VGA display output control module through a DDR slot; when the main BMC module is not connected with the mainboard, the sub-BMC module is responsible for providing a display function for the mainboard, after the main BMC module is connected with the mainboard, the main BMC module connects a display access of the main BMC module with the VGA display output control module through a pre-designed GPIO PIN PIN of the double-BMC signal switching module, and at the moment, the control right of the mainboard is controlled by the main BMC module, so that the remote management of the mainboard is realized.

Preferably, the control right of the mainboard is controlled by the main BMC module, so that remote management of the mainboard is realized, wherein the remote management comprises remote starting, shutdown and restarting actions; and detecting all main voltages and components on the mainboard in real time, and detecting humidity to adjust the rotating speed of the fan in real time.

Preferably, the DDR slot is a DDR3 slot.

The utility model discloses a double-BMC management system, the sub-BMC module is used for simple display output, and the main BMC module is used for full-function management; when the main BMC module is not connected with the mainboard, the work of the sub-BMC module only supports mainboard display, and after the main BMC module is connected with the mainboard, the main BMC module controls a change-over switch on the mainboard through a GPIO PIN channel of a pre-designed double-BMC signal switching module to take over a display right and a control right from the sub-BMC module, so that the main BMC module can realize system management of the main BMC module. The dual-BMC management system can well solve the upgrading and updating of the BMC management chip, and the main BMC management system can be easily upgraded in the earlier stage without changing the design function of the original mainboard. The method is convenient and flexible, can save the cost of the mainboard, and improves the competitiveness of the product price.
