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.

Specification WeOS 41
The WeOS operating system has been developed by Westermo for its current as
well as future range of Ethernet hardware products. This layer 2 and layer 3
switching solution enables Westermo to create complex multimedia ring networks
and routing solutions. WeOS not only provides solutions to many challenging
industrial networking issues, but also helps to protect investments by
ensuring the future availability of fully compatible solutions. WeOS is the
core of our latest ranges of Ethernet hardware allowing complex multimedia
ring networks and routing solutions to be created.
Westermo has many years of experience developing products for industrial
applications. At the heart of all Westermo networking solutions is the need
for ease of use. By standardising on a single operating system for all
Westermo Ethernet products this helps to simplify the installation, operation
and maintenance of individual devices and complete networks. Once a user is
familiar with a Westermo product, that knowledge can be readily applied to all
our other devices. A web screen simplifies the configuration of many
functions, whilst a command line interface allows for fine tuning.
WeOS incorporates unique functions that allow Westermo solutions to provide
integration paths for legacy equipment. WeOS also enables Westermo to deliver
a range of unique network security solutions, utilising elements such as
stateful inspection firewalls and the IEEE 802.1X standard. Remote secure
access can be provided using encrypted VPN tunnels. The WeOS Management Guide,
6101-3201, explains how many of these functions can be set up.
