Power management method, system, main control board and intelligent interface board

Abstract

The invention discloses a power supply management method, including: when the main control board specified that the status of power supply for intelligent interface board should be switched, then relevant status information shall be notified to the intelligent interface board, which may switch its own power supply status according to this status information. The invention still discloses a power supply management system, consists of main control board and intelligent interface board. The invention still discloses a main control board and an intelligent interface board. The invention may ensure the main control board under the powered on status, during the intelligent interface board out of work, the intelligent interface board may cut off the power supplies for partial chips, or completely powered off to save the system energy.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a power supply management method, a system, a main control board and an intelligent interface board. Background technique [0002] Routers and Ethernet switches undertake functions such as forwarding of Internet Protocol (IP) data packets and selection of transmission paths in the Internet. The main function of traditional low-end routers and switches is to collect and manage services, and they are generally located at the edge of the network. On the one hand, low-end routers and switches can meet the low-end performance requirements of general network equipment, and on the other hand, they also have a good price and cost advantage. However, the traditional middle and low-end routers rely on a single central processing unit (CPU) for business processing, and the traditional middle and low-end switches rely on dedicated chips with simple internal functions to realize the p...

Problems solved by technology

If intelligent power management cannot be implemented for the intelligent interface board, it will cause the intelligent interface board to still be in the normal power supply state when the intelligent interface board is not required to work

In this way, not only will energy be wasted, but also heat dissipation problems will be caused due to the large power consumption of the entire system.

For example: There are ports 1 to 4 on a switch, and the function of a certain intelligent interface board is virus protection, and it is stipulated that the packets entering from port 1 of the switch need to be protected against viruses, that is, they need to be sent to the intelligent interface board for virus protection processing, the packets entering from ports 2 to 4 do not need to be protected against viruses, that is, they do not need to be sent to the smart interface board, so it is likely that there will be no traffic on port 1 for a long period of time, so the smart interface The board does not perform any business processing. If the smart interface board is still powered at this time, it will cause a waste of energy
