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 212, Viper 112 and RFR-12-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 or alternatively, the device allows configurations to be updated by simply plugging in the unit and repowering.
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 EN50155.
Westermo understand that systems on railcars are required by the EN50155 standard to have a useful life of 20 years, so we use the highest quality components to deliver extended MTBF figures.
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.
