Unmanaged EN 50155 Switch
Viper-012
The Viper-012 is a basic unmanaged 12 port switch designed to meet the full requirements of the rail vehicle market. The incredi-
bly compact and robust housing ensures the unit can be built into tight and environmentally hostile spaces.
As is critical for all equipment to be installed in rail vehicles, the Viper has been externally tested across the complete spectrum of 
standards required by EN 50155. 
Westermo understand that systems on railcars are required by the EN 50155 standard to have a useful life of 20 years, so as well 
as using the highest quality components to deliver extended MTBF figures, we also implement features like the GORE-TEX® 
membrane in the IP67 enclosure to prevent water build up in the units. Due to the high vibration environment of the rail industry, 
we have also developed the Viper case with integral threading for the M12 connectors to ensure the IP67 seal is maintained for 
the life of the product. 
The EN 50155 standard requires mandatory performance and isolation testing. Not only does  Westermo meet these, we exceed 
them in order to meet the additional manufacturer requirements for train control.  Westermo’s Swedish factory has been building 
Ethernet switches for the railcar market for many years and fully understands the measures that are required to provide the 
highest quality manufactured solutions.
Meeting the requirements of the railcar environment, makes the Viper very well suited for deployment in any application with 
severe operating conditions and extreme environments.
