Industrial POE Switch – VIPER 212-P8

Industrial POE Switch - Viper-112-212-P8

The Industrial POE Switch Viper-212-P8 is a managed 12 port routing switch designed to meet the full requirements of the rail vehicle market. The Viper is capable of delivering up to 66 W of power across 8 of the ports, derived from the wide operating DC voltage of the unit. The Westermo WeOS operating system provides an extensive suite of IP networking standards allowing resilient and flexible networks to be created, meeting the needs of the rail market.

As is critical for all equipment to be installed in rail vehicles, the Viper has been externally tested across the complete spectrum of standards required by EN50155. A unique feature of this Viper is the galvanic isolation provided between the input DC voltage and the power delivered through PoE to the connected equipment.

Westermo understand that systems on railcars are required by the EN50155 standard, so as well as using the highest quality components to deliver extended MTBF figures, we also implement features like the Gore-Tex® membrane in the IP65 enclosure to prevent water build up in the units. Due to the high vibration environment of the rail industry, we have also developed the Viper case with integral threading for the M12 connectors to ensure the IP65 seal is maintained for the life of the product.

The EN50155 standard requires mandatory performance and isolation testing. Not only does Westermo meet these, we exceed them in order to meet the additional manufacturer requirements for train control. Westermo’s Swedish factory has been building Ethernet switches for the railcar market for many years now and understands the measures that are required to provide the highest quality manufactured solutions.
