The USB-M12 is a configuration backup device designed to meet the full requirements of the rail vehicle market. This device can be used with the Viper-112/212 ranges and RFR-212-FB, and allows the configuration of the switch to be saved.
The device can then be left attached to the switch for easy maintenance exchange of units. It also enables easy update of the switch configuration by attaching the device to the switch and cycling power.
As is critical for all equipment to be installed in rail vehicles, this device has been externally tested across the complete spectrum of standards required by EN 50155. Westermo understand that systems on railcars are required by the EN 50155 standard to have a useful life of 20 years, so we use the highest quality components to deliver extended MTBF figures.
The EN 50155 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 and understands the measures that are required to provide the highest quality manufactured solutions.
