3. Product Description
3.1. Product Description
The Viper-12A-PoE series consists of managed 12 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-12A-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-12A-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 PoE ports. Viper x12A-PoE is used when referring
to both models 112A-PoE and 212A-PoE.
