The Viper 8 series is a managed backbone routing switch optimized for the needs of the railway rolling stock market. Gbps ports cope with a high bandwidth backbone, consist ring and end devices.
The switch 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 very high MTBF for easy integration and low lifecycle cost.
Thorough type testing at independent ISO/IEC 17025 and ILAC MRA-certified labs, accredited to a wide range of standards, show that the Viper series fulfills EN 50155 and other requirements. The state-of-the-art Westermo production facility ensures the quality of each individual 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 consistent networks. The backup device accessory matches the Viper in robustness and offers easy configuration updates and backup.
