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 oper-
ating 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, recom mended fuse: 4 A slow. It must be possible to manually disconnect
power.
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.
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.
When this unit is operated at an ambient temperature above +55°C (+131°F),
+55°C (+131°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.
This unit must not be operating with removed covers or lids.
Do not attempt to disassemble 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 liquids (rain, beverages, paint etc), unless all
connectors and the ventilation membrane are sufficiently protected.
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.

Description
Functional description
RFR-212-FB is a 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 is equipped with rugged M12 Ethernet connectors and
full metal housing and it fulfills IP 65 ingress protection. The 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. RFR-212-FB supports QoS
(Quality of Service) with four priority queues and strict priority scheduling as well as
HoL (Head of Line Blocking Prevention), in order to assure a deterministic behaviour
of the network. In the event of power loss or other switch failure, the RFR-212-FB is
equipped with dual by-pass relays which can maintain communication through the switch
of dual backbone links.
