Viper-8 Series - 1

EN 50155 Managed Gigabit Routing Switch Viper-8 Series • Compact and powerful routing switch approved for rolling stock • Full speed routing capability • 8 x 1 Gbps ports • Single model 24-110 VDC (±30%) power range • Designed and built for extreme operational environments • Robustness-enhancing design features • Extensive range of approvals, by IEC/ISO 17025 certified laboratories • Quality-focused engineering and production located in Sweden • Powered by WeOS, Westermo's proven network operating system • High level cyber security • Easy to use Rolling Stock Industrial Immunity Industrial Emission Safety Industrial Equipment Railway Trackside Fire Protection The Viper-8 series is a managed backbone routing switch optimised for the needs of the railway rolling stock market. High speed Gbps ports and full speed routing capability cope with high bandwidth backbone, consist ring and end-devices. The Viper-8 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 in 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 ingress of water and dust. An overall optimised 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-8 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 consist networks. The backup device accessory matches the Viper in robustness and offers easy configuration update and backup.
