Safety
Before installation:
Read this manual completely and gather all information on the unit. Make sure
that you understand it fully. Check that your application does not exceed the safe
operating specifications for this unit.
This unit should only be installed by qualified personnel.
This unit should be built-in to an apparatus cabinet, or similar, where access is
restricted to service personnel only. The power supply wiring must be sufficiently
fused, and if necessary it must be possible to disconnect manually from all power
supply. Ensure compliance to national installation regulations. This unit relies on
convection heating. Make sure that it is installed so that the ambient temperature
is within the specified temperature range, e.g. by avoiding obstruction of the
airflow around the unit. Also check chapter CEN/TS 45545-2 mounting notes.
Before mounting, using or removing this unit:
Prevent access to hazardous voltage by disconnecting the unit from all power supply.
WARNING
Do not open connected unit. Hazardous voltage may occur within this unit when
connected to power supply.
Before powering-up, a protective earthing conductor must be connected to the
protective earthing terminal and have a cross-sectional area of at least 1.5 mm².
Note that this unit can be connected to two different power sources.
When this unit is operated at an ambient temperature above +60°C (+140°F), the
External Surface of Equipment may exceed Touch Temperature Limit according to
EN/IEC/UL 60950-1. To reduce the risk of fire, use only No. 26 AWG or larger
telecommunication line cord.

Care recommendations
Follow the care recommendations below to maintain full operation of unit and to fulfill
the warranty obligations:
…Do not attempt to dissassemble the unit. There are not any user serviceable
parts inside.
…Do not drop, knock or shake the unit. Rough handling above the specification
may cause damage to internal circuit boards.
…Do not use harsh chemicals, cleaning solvents or strong detergents to clean the
unit.
…Do not expose the unit to any kind of liquid (water, beverages, paint etc),
unless all connectors are connected or fitted with protective caps (delivered
with the unit), tightened to the specified torque. Connected cables must have
the appropriate ingress protection code.
…Do not use or store the unit in dusty or dirty areas, unless all connectors and
the ventilation membrane are sufficiently protected.
…Do not cover or bring mechanical force to the ventilation membrane on the
back of the unit.
If the unit is not working properly, contact the place of purchase, nearest Westermo
distributor office or Westermo Tech support.
Maintenance
No maintenance is required, as long as the unit is used as intended within the specified
conditions.

Description
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.
