The Viper-212A-T5G-P8-HV is a managed 12 port routing switch optimised for the needs of the railway rolling stock market.
PoE ports offer effective powering of end-devices. 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 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 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 on 100 Mbps ports 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 update and backup.
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.
