    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.

    Abstract: Disclosed is a circuit for realizing passivation of an intelligent optical distribution interface disc in a machine disc enable manner, which relates to the field of optical communications. In the present invention, a distribution port is separated from distribution management, all management circuits on a distribution interface disc are moved out, and all control and management functions are achieved on a distribution management disc, to enable passivation of a distribution interface disc circuit, i.e. any active electronic devices such as integrated circuits, triodes, etc. which are easily damaged by static electricity and affected by fouling are not placed on the distribution interface disc any longer, and power lines are not introduced in the distribution interface disc. Using the present invention, no matter whether in a fusion-distribution integration or fusion-distribution separation design, during onsite construction, a distribution disc has both strong anti-static capability and fouling-resistant capability. When the fusion-distribution integration design is used, the device cost can be reduced, the device production process can be reduced, and the device performance and the distribution density can be increased. When the fusion-distribution separation design is used, even an optical fiber fusion splice point on the distribution disc generates failure, over-high requirements may not be put forward for maintenance and construction.
