It is of great significance to improve the network equipment utilization in the network laboratory. This paper introduces an unattended and full-automatic laboratory management system that can realize a remote openness all day. The hardware system is composed of the server, intelligent outlet and multi-serial-port card. The software system is composed of Web server, SQL database, terminal server and LabServer. Users can perform experiments through the web browser. The system can turn the physical equipment into multiple logical topologies and realize full-automatic start-up and shut-down through the intelligent outlet.
