2.2. Safety Information
Before installation:
Read this manual completely and gather all information available on the product. Make sure
it is fully understood. Check that your application does not exceed the safe operating
specifications for the product.
WARNING - SAFETY DURING INSTALLATION
The product must be installed and operated by qualified service personnel
and installed into an apparatus cabinet or similar, where access is
restricted to service personnel only. For Ibex products, outdoor
installation is allowed.
During installation, ensure a protective earthing conductor is first
connected to the protective earthing terminal (only valid for metallic
housings). Westermo recommends a cross-sectional area of at least 4
mm2.
Upon removal of the product, ensure that the protective earthing
conductor is disconnected last.
WARNING - HAZARDOUS VOLTAGE
Do not open an energised product. Hazardous voltage may occur when
connected to a power supply.
WARNING - PROTECTIVE FUSE
The power supply wiring must be sufficiently fused.
It must be possible to disconnect manually from the power supply. Ensure
compliance to national installation regulations.
Replacing the internal fuse must only be performed by Westermo qualified
personnel.
WARNING - POWER SUPPLY CONNECTION
There are safety regulations governing the power source that can be used
in conjunction with the product. Refer to Interface Specifications.
Ibex-RT-220 Series 5

WARNING - RADIO PRODUCTS
Observe the usage limitations of radio products at filling stations, in
chemical plants, in systems with explosives or potentially explosive
locations.
The product may not be used in airplanes. Exercise particular caution near
personal medical aids, such as pacemakers and hearing aids. Never
perform work on the antenna system during a thunderstorm.
To fulfill human safety, a minimum separation distance of 20 cm or more
should be maintained between the antenna of the product and personnel
during operation.
CAUTION - HOT SURFACE
Be aware that the surface of this product may become hot. When it is
operated at high temperatures, the external surface may exceed Touch
Temperature Limit according to the product's relevant electrical safety
standard.
This product complies with Touch Temperature Limits throughout its
operational temperature range.
CAUTION - CORROSIVE GASES
If the product is placed in a corrosive environment, it is important that all
unused connector sockets are protected with a suitable plug, in order to
avoid corrosion attacks on the gold plated connector pins.
CAUTION - CABLE TEMPERATURE RATING FOR FIELD
TERMINAL WIRES
There may be a requirement on the minimum temperature rating of the
cable to be connected to the field wiring terminals, see Interface
Specifications.

3.1. Product Description
The Ibex-RT-220 can be configured as a WLAN Access Point, Client or Bridge. It is
designed for onboard and infrastructure Wi-Fi installations in public transport and harsh
environments. The 802.11 WLAN radio is operating at 2.4 GHz and 5 GHz frequency
bands.
Figure 3. Ibex-RT-220-LV/Ibex-RT-220-HV block diagram
The Westermo configuration management tool, WeConfig, can be used for discovery and
basic configuration and maintenance. The configuration can be done via SNMP or via
WebGUI. The status information is available in local LED status indicators, and through
SNMP/WebGUI.
The Ibex-RT-220 is designed to withstand tough environmental conditions and can be
remotely managed using web browser or SNMP management tools.
Integrating hardware, software and network design support tools, this router platform
offers advanced capabilities, the lowest total cost of ownership and will create the most
reliable and resilient networks.
The Ibex-RT-220 is engineered to maintain uninterrupted data communication, even in
exceptionally harsh environments. Tested and certified to withstand extreme temperatures,
vibrations and shocks, these routers only use industrial grade components which
contributes towards a market leading mean time between failure (MTBF), maximized
service life, and reduced operational and life cycle costs.

4. Installation
4.1. Mounting
The product is fixed with the four fixing points located at the corners of the product. M5
or M6 screws are used for the fixation of the product. The screws are tightened with min.
3.0 Nm (fixing screw ISO 898/1, quality class 8.8).
NOTICE
All four specified fixing points must be used for fixing. The installation
surface should be flat to have all fixing points connected to the surface.
NOTE
For indoor installation, consider additional protection against dust to
ensure proper heat dissipation.
NOTE
For outdoor installation, consider additional protection against sun
radiation, dust and dirt to optimize ambient temperature range.
NOTE
Unused connectors must be covered by a protective cap (delivered with
the product), tightened to the specified torque in order to fulfill the
specified ingress protection code.
4.2. Factory Reset
To reset the product into factory default settings, a reset adapter is needed which is
plugged into one of the Ethernet ports X1 or X2 during startup.
Art. no. Description
3623-0799 Factory Reset Plug, X-coded
Factory reset procedure
1. Plug the factory reset adapter to one of the Ethernet interfaces.
18 Ibex-RT-220 Series

2. Power the product.
3. Wait until factory reset adapter is detected. This is indicated by solid ORANGE OPR
LED and RED ERR LED.
4. Remove factory reset adapter within 15 seconds.
5. Successful initiation of the factory reset is indicated by blinking ORANGE OPR LED
and RED ERR LED.
4.3. Earth connection
For correct function, the earth connection at the grounding point needs to be properly
connected to a solid ground. An M5 grounding screw at the housing is used for grounding.
A short wire with a cross section of at least 4 mm2 shall be used. The grounding wire is set
below the rip-lock washer. The nut is fixed for good reliable grounding contact. The
tightening torque of the nut shall be 2.0 Nm.
DC X2 X1
Figure 7. Earth connection
NOTICE
Do not use equipment without protective earth connection.
4.4. Connection of Cables
Recommended tightening torque for the M12 connectors is 0.6 Nm. All M12 connections
are screw connections.
When connecting the power cable, ensure that the pins are connected correctly before
tightening the power cable to the unit.
NOTE
This product has no replaceable fuse and should be connected via an
external fuse for protection.
4.5. Cooling
This product uses 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 product.
Ibex-RT-220 Series 19

It is recommended to install the product in areas where the natural convection airflow is
not blocked and that there is enough spacing around the product.
Figure 8. Installation with reduced natural convection
airflow Figure 9. Installation with natural convection airflow
When operating the product at high ambient temperatures, it is recommended to mount
the product to a metallic base plate to improve the heat dissipation. The base plate
increases the surface to spread the heat.
