Description

technical field

[0001] The invention belongs to the technical field of power supply for communication equipment, and more specifically relates to a power supply system for communication equipment and a control method thereof. Background technique

[0002] Usually, in order to ensure the reliability of the communication equipment power supply system, in addition to the N (N ≥ 1) main switching power supply modules for normal power supply in the actual application of communication equipment, the same number of N (N ≥ 1) standby switching power supply modules will also be introduced. Switching power supply module, 2N switching power supply modules are introduced into the communication equipment and the number of power supply terminals to be provided in the computer room is also 2N. The communication equipment uses N or 2N partition planes to supply power to all the machine disks in the communication equipment.

[0003] The communication equipment adopts N+N redundant backup mod...
