3.1. Product Description
The Viper-12A series is a series of managed 12 port 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 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 fulfilles 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.
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.
