Over-temperature power-off protection method, logic device, service board and network system

Abstract

The disclosure provides an over-temperature power-down protection method, a logic device, a service board and a network system, and relates to the technical field of network communication. The method includes: receiving an interrupt signal sent by a temperature detection chip of the service board; When the communication of the control board is abnormal, judge whether the service board satisfies the power-down condition according to the interruption signal; if so, output a power-down indication signal to the power management chip, so that the power management chip controls the power-down of the service board. The over-temperature power-down protection method, logic device, service board, and network system provided by the embodiments of the present disclosure can power off the service board in time to prevent the temperature of the service board from being too high. The operation of the control board effectively reduces the dependence of the temperature monitoring and management process of the service board on the main control board, thus greatly alleviating the potential safety hazard caused by the overheating of the service board single board.

Description

technical field [0001] The present disclosure relates to the technical field of network communication, in particular to an over-temperature power-down protection method, a logic device, a service board and a network system. Background technique [0002] With the advent of 5G (5th-Generation, fifth-generation mobile communication technology), users have more and more demands for high network bandwidth, in order to meet user needs. Network equipment vendors need to continuously improve equipment performance, board port density and port speed to meet customer needs, followed by a continuous increase in power consumption of boards, and board overheat protection has become a key component of system management. an important job. If it is not managed properly, it will cause burning and damage to the veneer, and it will cause a fire and bring greater economic losses to users. [0003] In the prior art, the main control board in the network system is mostly used for temperature mon...

AI Technical Summary

Problems solved by technology

If it is not managed properly, it will cause the board to be burned and damaged if it is light, and it will cause a fire if it is serious, which will bring greater economic losses to users.

[0003] In the prior art, the main control board in the network system is mostly used for temperature monitoring and management, so that the temperature monitoring and management process is highly dependent on the main control board. When the main control board fails, it is easy to cause an over-temperature fault. There are great security risks in the operation of the network system
