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

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.

By-Pass functionality
The by-pass functionality in RFR-12-FB secures connection in case of power failure in
one of the switches. If a switch has power loss an internal relay in RFR-12-FB will by-pass
the switch and bridge two Ethernet ports.
By-pass interfaces
In case of power failure X9 will be by-passed to X11 and X10 will be by-passed to X12.
Internally the switch will bypass

Mounting
There are four 6 mm bore holes intended for mounting the unit. The unit can be
mounted vertical or horizontal. Use four M5 screws with 12 mm washer on a flat and
stable surface.
Connection of cables
Recommended tightening torque for the M12 connectors: 0.6 Nm.
Note that unused connectors must be covered by a protective cap (delivered with the
unit), tightened to the specified torque, in order to fulfill the specified ingress protection
code.
Removal
Disconnect all cables and unscrew the unit from the wall.
Time For Replacement < 15 minutes
Cooling
This unit relies on convection cooling. 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.

Getting Started
This product runs Westermo Operating System (WeOS) which provides several
management tools that can be used for configuration of the unit.
• IPConfig tool
This is a custom Westermo tool used for discovery of attached Westermo units.
• Web
Configuration of the unit using the web browser.
• CLI
Configuration of the unit via the Command Line Interface.
If the computer is located in the same subnet as the switch you can easily use a web
browser to configure the unit. Within the web you can configure most of the available
functions.
For advanced network settings and more diagnostic information, please use the CLI.
Detailed documentation is available in the chapter ”The Command Line Management
Tool” in the WeOS management guide.
Factory default IP address: 192.168.2.200
Netmask: 255.255.255.0
Gateway: Disabled
Note! If you are not sure about the subnet – consult your network administrator.
Configuration
Configure the unit via Webbrowser
The unit can easily be configured via a Web browser.
Open the link http://192.168.2.200 in your web browser, and you will be prompted with
a Login screen, where the default settings for Username and Password are:
Username: admin
Password: westermo
Once you have logged in, you can use the extensive integrated help function describing
all configuration options. Two common task when configuring a new switch is to assign
appropriate IP settings, and to change the password of the admin account.
The password can be up to 64 characters long, and should consist of printable ASCII
characters (ASCII 33-126); 'Space' is not a valid password character.
Note! Version of IP Config tool must be 10.4 or higher.

18
6641-2222
Factory default on RFR-12-FB
It is possible to set the unit to factory default settings by using Ethernet M-12 cables.
1. Power off the switch and disconnect all Ethernet cables.
2. Connect the first Ethernet cable between Ethernet port X1 and Ethernet port X6.
Then connect the second Ethernet cable between Ethernet port X2 and Ethernet
port X5.
The ports need to be connected directly by an Ethernet cable, i.e., not via a hub or
switch. Use a straight cable – not a cross-over cable – when connecting the ports.
3. Power on the unit.
4. Wait for the unit to start up. Control that the ON LED is flashing red.
The ON LED flashing indicates that the unit is now ready to be reset to factory
default. You now have the choice to go ahead with the factory reset, or to skip
factory reset and boot as normal.
• Go ahead with factory reset:
Acknowledge that you wish to conduct the factory reset by unplugging one of the
Ethernet cables. The ON LED will stop flashing.
This initiates the factory reset process*, and the unit will restart with factory
default settings. When the switch has booted up, the ON LED will show a green
light, and is now ready to use.
• Skip the factory reset:
To skip the factory reset process, just wait for approximately 30 seconds
(after the ON LED starts flashing RED) without unplugging the Ethernet cable.
The switch will conduct a normal boot with the existing settings.
* Note Do not power off the unit while the factory reset process is in progress.
