  • 1x USB port
  • 5x 1Gbps ports
  • 7x 100 Mbps ports
  • EN 50155 Managed Gbps Routing Switch


The Viper-212A-T5G is a managed 12-port routing switch optimized for the needs of the railway rolling stock market. Gbps ports cope with high bandwidth devices such as access points and NVRs (Network Video Recorders).

The Viper 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 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 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 on 100 Mbps as well as Gbps ports. The powerful layer 3 routing capability is very useful for separating networks in complex applications. The backup device accessory matches the Viper in robustness and offers easy configuration updates and backups.

Meeting the requirements of the railcar market, the Viper is very well suited for deployment in any other application with severe operating conditions and tough environments, for instance in the mining industry.
