Control method of multi-board card equipment, multi-board card equipment and medium

The invention discloses a control method of multi-board card equipment. The control method comprises the following steps that a host electric management assembly obtains power supply output power of the multi-board card equipment and total operation power of the multi-board card equipment from an electromechanical management assembly; when the power supply output power and the total operation power meet a preset power-on condition, the host electric management assembly controls a board card where the host electric management assembly is located to be powered on; and the host electric management assembly sends a power-on message to each slave electromechanical management assembly, so that the slave electromechanical management assemblies control the board cards where the slave electromechanical management assemblies are located to be powered on when receiving the power-on message. The invention further discloses multi-board card equipment and a computer readable storage medium, and theeffect of improving the r
