Embodiment Construction

[0032] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] Such as figure 1 As shown in the electromechanical management system based on the electromechanical management bus, the electromechanical management bus interface circuit of the system is close to the backplane, and each electromechanical management node does not have a mechanical switch in series. When the physical layer of the bus interface chip is damaged, it cannot be connected from the bus. Get out. and figure 2 It is a block diagram of the electromechanical management node of the electromechanical management system of the communication equipment in the present invention, and figure 1 In comparison, the system connects a controlled mechanical switch in series near the backplane side of the electromechanical management bus interface circuit of each electromechanical management node (including the chassis management controller SH...

Abstract

The invention discloses a fault node positioning and isolating method of electromechanical management buses of a communication device. The method comprises following steps: recording the communication states of the electromechanical management buses by an operating SHMC in a communication process; carrying out statistic analysis to communication state data, judging whether corresponding buses generate communication unrecoverable abnormities; when the communication unrecoverable abnormities are generated, sending instructions to the electromechanical management nodes by the SHMC through a normal electromechanical management bus, thus controlling corresponding bus mechanical switches by the instructions, wherein the electromechanical management nodes are hooked on the abnormal electromechanical management buses; coordinating the nodes on the abnormal electromechanical management buses so as to carry out mutual communication tests, positioning fault nodes, returning the positioning information of the fault nodes; displaying electromechanical management bus abnormal warnings and the positioning information of the abnormity caused fault nodes by the SHMC through a remote network management system, thus realizing remote warning positioning instruction. According to the method of the invention, the electromechanical management system can automatically discover and position the fault nodes causing the abnormities of the electromechanical management buses; the maintenance cost is effectively reduced; and the system reliability is improved.

Description

technical field [0001] The invention relates to communication equipment, in particular to a method for locating and isolating faulty nodes of an electromechanical management bus of communication equipment. Background technique [0002] With the gradual increase in the capacity of communication equipment, its power consumption is also increasing, which makes the power supply and heat dissipation of communication equipment more and more complicated. Mechanical and electrical management of communication equipment. [0003] Such as figure 1 As shown, the block diagram of the electromechanical management system based on the electromechanical management bus. The electromechanical management system is realized based on two independent hardware serial buses, such as the I2C bus and the CAN bus. This scheme has fewer serial bus signal lines, which is convenient for implementation and communication The speed can also meet the requirements of electromechanical data transmission. How...
