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 enterin

Embodiment Construction

[0055] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0056] The core idea of ​​the present invention is: when the main control board is powered on, it collects the power state supported by each intelligent interface board, and if it detects that the power state of the intelligent interface board needs to be converted according to the business requirements of the intelligent interface board, it notifies the intelligent interface board The board transitions power states.

[0057] Fig. 2 has provided the working state of the smart interface board defined in the present invention and its transition schematic diagram, as shown in Fig. 2, the working state of the smart interface board includes three kinds: normal operation state B0, sleep state B1 and physical closing state B2, in:

[0058] B0: The intelligent interface board is in the normal operation mode, and can be switched to the B1 sta...

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...
