Functional description
RFR-12-FB is switch developed for rail on board and industrial applications approved
according to EN 50155. To meet the environmental requirements from rail and harsh
industrial applications the switch has rugged M12 Ethernet connectors and full metal
housing. The switch fulfill IP 65 degree of protection. Our unique FRNT (Fast Recovery
of Network Topology) technology is the fastest protocol on the market to re-configure
a network in the event of any failure of a link or hardware. Real-time properties are
implemented in the RFR-12-FB in order to achieve determinism for real time critical
applications. The switch also supports QoS (Quality of Service) with four priority queues
and strict priority scheduling as well as HoL (Head of Line Blocking Prevention). All to
assure that the data network is deter ministic. RFR-12-FB also has a by-pass relay that
by-pass the unit in case of power loss to the switch.
