3. Product Description
3.1. Product Description
The Viper TBN is a managed backbone routing switch optimised for the needs of the
railway rolling stock market. The dual bypass relay ensures that aggregated links between
cars are maintained, even if there is a power failure in one car. Gbps ports cope with high
bandwidth backbone, consist ring and end-devices.
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 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 ensures communication between the backbone and
consist networks and offers full support for IEC 61375, including TTDP network
inauguration and TRDP realtime data protocol. The backup device accessory matches the
Viper in robustness and offers easy configuration update and backup.
