Abstract
It is to realize a network management system excellent in its reliability which can prevent a wrong connection when a field wireless management station having a redundant structure is installed, and can make a backbone network redundant so as to improve a trouble resistance. In a network management system in which filed wireless management stations having gateway functions and system management functions incorporated are redundantly connected together, the plurality of field wireless management stations 11, 12 are connected to each other through a synchronizing cable 30 and synchronizing connectors Can, CNb provided in the synchronizing cable 30.
Claims6
A network management system in which field wireless management stations having gateway functions and system management functions incorporated are redundantly connected together,
- wherein the plurality of field wireless management stations are connected to each other through a synchronizing cable and synchronizing connectors provided in the synchronizing cable, the respective synchronizing connectors for the field wireless management stations being physically configured different from each other,
- wherein the synchronizing connectors comprise a first connector for directly connecting to a first of the plurality of field wireless management stations and a second connector for directly connecting to a second of the plurality of field wireless management stations, and
- wherein the synchronizing cable provides a physical connection between the first connector and the second connector.
