The redundant server power supply module provided by the utility model is arranged in a server case and comprises an outer cover and a power supply unit, the outer cover comprises a top wall and two side walls extending downwards from the two sides of the top wall, and a U-shaped structure is defined by the top wall and the two side walls. The plurality of power supply units are sequentially arranged in the U-shaped structure, each power supply unit comprises a power supply shell and an elastic fixing piece, and the elastic fixing piece is installed in the power supply shell; wherein an elastic sheet, extending outwards from an opening in the top plate of the power supply shell, of the elastic fixing piece abuts against the top wall of the outer cover, and the elastic fixing piece is used for fixing the power supply unit in the outer cover. According to the server power supply module, the plurality of power supply units are adopted for supplying power, each power supply unit independently supplies power, and the power supply units are detachable, so that when a power supply is maintained, the damaged power supply unit can be pulled out from the rear part of a server case to be maintained under the condition that the server is not powered off, and the server power supply module is very convenient to operate and high in efficiency.

During disasters, widespread power outages occur, and after power is restored, power shortages arise, making it impossible to maintain power supply to evacuation centers, medical facilities, and communication equipment. [Solution] The present invention provides a power supply maintenance system that enables the maintenance of power supply both before and during supply by identifying the required amount of power corresponding to the supply period or the remaining period of the supply period based on the load to be supplied, identifying the amount of power that can be supplied by multiple power sources, excluding or limiting power sources that do not meet the required amount of power from candidates, determining the configuration of a power source or group of power sources that will satisfy the required amount of power over the supply period, and changing the configuration if there is a possibility that the supply maintenance conditions will not be met during supply. Furthermore, this invention is applicable to various uses, including power supply to evacuation centers, medical facilities, and communication equipment during disasters.
