Problems solved by technology

[0003] However, the operating system on the processor board cannot communicate with the chassis management unit at present, so if the operating system installed on the processor board is running, if you hit a wrench or trigger other devices of the same nature to directly cut off the power, the system will be treated as an unexpected shutdown. , it will damage the software and hardware of the single board, and it is not sure whether the service is switched to the normal processor board during the shutdown process.

Abstract

A method for switching of power supply of single board includes receiving power-off signal by base plate management controller and sending said signal to frame management unit, generating power-off command by frame management unit according to said power-off signal, obtaining power-off command by operation system and making turn-over on services, switching off operation system after service turn-over is finished and using base plate management controller to switch off power supply of single board after said operation system is switched off. The system for realizing said method is also disclosed.

Description

technical field [0001] The invention relates to platform management technology in the communication field, and is specifically applied to a single board management method and system in ATCA (Advanced Telecom Computing Architecture, advanced telecommunication computing structure). Background technique [0002] Advanced Telecom Computing Architecture (ATCA for short) is a new-generation computing platform standard formulated by the Industrial Computer Manufacturers Group (PICMG for short) at the end of 2001. It provides a cost-effective, modular-based, compatible, and scalable hardware architecture for next-generation converged communications and data network applications. The PICMG 3.0 specification is the core specification in the ATCA family, which mainly defines the mechanical structure, power supply, heat dissipation design, interconnection, system management and data transmission in the ATCA series specifications. Such as figure 1 As shown, the ATCA-based architecture ...
