Description
Westermo Viper Series 20-Port EN 50155 Layer 2/3 Managed PoE Ethernet Switches, M12 Connectors, 24-38 or 48-110 VDC Powered, -40 to +70 deg. C.
The Viper-20A-PoE series consists of managed 20 port routing switches 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-20A-PoE 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-20A-PoE series is very well
suited for deployment in any other application with severe operating conditions and
tough environments, for instance in the mining industry.
3.2. Available Models
All switches are managed and have eight or twelve PoE ports. Viper x20A-PoE is used
when referring to both models 120A-PoE and 220A-PoE.
