Abstract

The present application provides a power control method and device. The method includes: determining the power-off sequence of the boards; the power-off sequence is the first switching network board in the redundant state, the first service board in the redundant state, The second SFU in the idle state, the second service board in the working state, and the third SFU in the working state; when the power supply fails, obtain the actual input power of the power supply and the expected power of the board; When the power used is greater than the actual input power, the power-off operation is performed according to the power-off sequence, so that the expected power of the remaining boards after power-off is not greater than the actual input power. Through the technical solution of the present application, the use of current services can be guaranteed as much as possible, and the reliability of network equipment can be improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular, to a power control method and device. Background technique [0002] A network device (such as a router, a switch, etc.) may include multiple boards, and the types of the boards may be main control boards, service boards, and switching fabric boards. When the actual input power of the network device is insufficient, all boards may not be able to support the work. Therefore, it is necessary to power off some boards to ensure the normal operation of the remaining boards. [0003] In practical applications, considering that after the main control board is powered off, the service board and the SFU cannot work normally. After the SFU is powered off, the bandwidth of the service board will be affected, but after the service board is powered off, it will not affect other Therefore, the power-off sequence can be the service board, the switching network board, and the ...
