Abstract: A method for locating and isolating a failed node of an electromechanical management bus in a communication device. The method includes, in a communication process, an SHMC in operation records communication states of electromechanical management buses; the SHMC in operation performs calculation and analysis operations on data associated with the communication states, and determines whether there is an irrecoverable communication abnormality in a corresponding bus; if so, the SHMC sends, by means of a normal electromechanical management bus, a command to an electromechanical management node subordinate to the abnormal electromechanical management bus, such that the electromechanical management node controls a corresponding mechanical switch of the bus, coordinates respective nodes of the abnormal electromechanical management bus to conduct mutual communication tests with each other, locates a failed node, and returns location information of the failed node.
