TNS5500 series are 12-port 100M/Gigabit layer 2 managed industrial Ethernet switches designed for rail transit. This series of products conform to EN50155 and EN50121 industrial standards. Ethernet interface adopts reliable M12, which can be used in scenes with strenuous vibration and shock. This series include four types of products and provide Gigabit M12 and 100M M12 interfaces. It adopts 1U rack-mounted or wall mounting to meet the requirements of different application scenes.

Network management system supports various network protocols and industrial standards, such as STP/RSTP, 802.1Q VLAN, QoS, DHCP Server, DHCP Client, IGMP Static Multicast, LLDP, Port Trunking, Port Mirroring and so on. It also possesses complete management functions, including Port Configuration, Port Statistics, Port IP Binding, Access Control, Network Diagnosis, Rapid Configuration, Online Upgrading, and supports CLI, WEB, Telnet, SNMP and other access methods. It can provide users with good experience with friendly design of network management system interface, simple and convenient operation.

When the port link failure occurs, ALARM indicator will be bright and send out alarm, meanwhile, alarm device connected to the relay will send out alarm for rapid scene troubleshooting. Hardware adopts fanless, low power consumption, wide temperature and voltage design and has passed rigorous industrial standard tests, which can suit for the industrial scene environment with harsh requirements for EMC. It’s specially designed for rail transit industry and can be widely used in vehicle-mounted PIS, CCTV, Video Monitoring, Train Control and other systems.
