3. Product Description
3.1. Product Description The Viper-12A series consists of managed 12 port
routing switches optimised 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-12A 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 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 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-12A series is very
well suited for deployment in any other application with severe operating
conditions and tough environments, for instance in the mining industry.
