An analysis is made of some typical cases selected from the faults encountered in the operational maintenance of the meteorological information system. The corresponding countermeasures are presented. In the case of failure in uplink packet transmission and firewall equipments resulting in abnormal data reception， the exclusion method is adopted， with which the scope of failure can be narrowed quickly， so to locate failure points， and according to the routing trend of the network topological graph， the method of segmental check is used to quickly track the location of packet transmission failure caused by abnormal communication network. In the case of downlink packet transmission failure， the causes can be found quickly by means of the method of reverse direction， according to the flow of meteorological data downlink broadcast.
