Description
Viper-208-TBN series consists of powerful, managed 8-port backbone routing switches, optimized for the needs of the railway rolling stock market. The dual bypass relay ensures that aggregated links between cars are maintained, even if one car has a power failure. Gbps ports and wire-speed routing cope with a high bandwidth backbone, consisting of ring and end devices.
The Viper-208-TBN series is designed to withstand the tough environment on-board trains, exposing the switch to constant vibration, extreme temperatures, humidity, and a demanding electrical environment.
A GORE-TEX® membrane prevents internal condensation. Threading integrated into the chassis provides for additional vibration resistance. High-level isolation between all interfaces enables direct connectivity to vehicle auxiliary power and protects against overvoltage and flashover. IP67 protection prevents the ingress of water and dust. An overall optimized design results in an extremely compact package in combination with a very high MTBF for easy integration and low lifecycle cost.
Thorough type testing at independent labs certifies compliance to a wide range of standards, not least EN 50155, where the highest class is achieved in all aspects. The state-of-the-art Westermo production facility ensures the quality of each unit, e.g., through temperature cycling burn-in testing.
The WeOS operating system offers an extensive suite of IP networking features for resilient and flexible networks, e.g,. the
FRNT ring protocol with very fast failover. The powerful layer 3 routing capability ensures communication between the backbone and consists of networks and offers full support for IEC 61375, including TTDP network inauguration and TRDP Realtime data protocol. The backup device accessory matches the Viper-208-TBN series in robustness and offers easy configuration updates and backup.
You can also find the Viper-208-T4G-TBN, Viper-208-TBN, and Viper-208-T8G models in the Managed Ethernet Switches.
