Description
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 the 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, shows that the Viper series fulfills EN 50155 and other requirements. The state-of-the-art Westermo production facility ensures the quality of each 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 on 100 Mbps ports and Gbps ports. 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.
You can also find the Viper-120A-P8-LV, Viper-120A-T4G-P8-HV, Viper-220A-P8-LV, and Viper-220A-T4G-P8-LV models in the Managed Ethernet Switches.
