Problems solved by technology

Therefore, if there is no master node ShMC on the chassis or the master node ShMC is abnormal and cannot manage the slave node IPMC, it cannot respond to the activation request command of the slave node IPMC and send an activation command to activate the ATCA board, so the FRU can only stay in the In the M2 state, it cannot enter the M4 state, so that the ATCA board cannot be powered on and work, and the availability and reliability of the device are reduced.

Embodiment Construction

[0041] In the IPMI subsystem of the prior art, the power management module in the IPMC handles the power-on / off process of the ATCA board and the power control of the board according to the state transition and operation process stipulated in the PICMG specification. Because the PICMG specification stipulates that the ATCA board can be powered on only after the master node ShMC responds to the activation request and sends an activation command to activate the ATCA board. Therefore, there is no master node ShMC on the chassis, or the master node ShMC exists but cannot manage the slave nodes. In the case of IPMC, the board cannot be powered on and work.

[0042] For this reason, the present invention aims at this problem and improves the IPMC and ShMC, so that the ATCA single board can also be powered on and work when there is no main node ShMC or the main node ShMC exists but cannot be managed. For the convenience of description, in the present invention, when there is no maste...

Abstract

The IPMI sub system includes main node ShMC and slave node IPMC. Main node and slave node are communicated through intelligent platform management bus. Characters are that the IPMI sub system also includes uncontrolled setup interface module; uncontrolled setup process module; main node on-position module, and uncontrolled power on control module. The uncontrolled setup interface module and the uncontrolled setup process module are mainly in use for setting up uncontrolled parameters in advance. The main node on-position module is in use for determining whether main node is on position, and when main node is not on position, the module sends control signal to the uncontrolled power on control module to make the uncontrolled power on control module control single board to turn power on. Themode includes options: one time uncontrolled powerup and permanent uncontrolled powerup so as to raise usability, reliability and flexibility of device.

Description

technical field [0001] The invention relates to an advanced telecommunication processing framework, in particular to an IPMI subsystem and an ATCA single board power-on method. Background technique [0002] As telecom network products become increasingly mature, the requirements for product reliability and maintainability are getting higher and higher. The maintenance and management of out-of-band channels has become an important means to improve product reliability and maintainability. They have integrated out-of-band maintenance management systems in their respective products. The PICMG 3.X series specifications formulated by PICMG (PCI Industrial Computer Manufacturing Organization) are also based on IPMI (Intelligent Platform Management Interface, Intelligent Platform Management Interface) technology to realize the ATCA (Advanced Telecommunications Computing Architecture, advanced telecommunications processing architecture) of the telecommunications architecture. specif...
