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.
This product should only be installed by qualified personnel.
This product 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 it manually from all power supply. Ensure compliance to national installation
regulations.
This product relies on convection cooling. To avoid obstruction of the airflow around the
product, follow the spacing recommendations. See Cooling chapter.
WARNING - PROTECTIVE EARTHING

CABLE
Apply the protective cap (delivered with the HV product) on the power
cable, according to the illustrated steps below. To prevent accidentally
pulling out wires, make sure the power cable and the wires are firmly
attached to the protective cap. For screw connectors, make sure the
screws are properly tightened, as well as routing the wires separately from
other wires.

3. Product Description
3.1. Product Description
The RedFox industrial rack is a high performance industrial Ethernet switch designed for
high network traffic applications. Various port configurations are available that can be
further customised with SFP transceivers. RedFox is powered by WeOS, the Westermo
network operating system.
RedFox-5528 is designed for 19” cabinet according to the ETSI standard, which makes it
suitable for use in control room networks as well as for cabinets installed along railway
trackside installations. RedFox-5528 is designed to run efficiently from a DC power supply
(not considered DC mains). The unit is also equipped with configurable I/O fault contact
that makes it ideal for easy installations and monitoring in industrial applications.
Only industrial grade components are used, which gives Redfox- high MTBF hours that
ensures a long service life. A wide operating temperature range of -40 to +74°C (-40 to
+165°F) can be achieved with no moving parts or cooling holes in the case. RedFox has
been tested both by Westermo and external test labs to meet many standards regarding
EMC, isolation, climate, vibration and shock, all to the highest levels suitable for heavy
industrial environments and rail trackside application.
WeOS has been developed to allow offer cross platform and future-proof solutions. WeOS
can deliver 20 ms ring recovery performance even for networks with video or EtherNet/IP
traffic. For more WeOS functionality, please see the WeOS datasheet.

4.2. Earth Connection
For correct function, the earth connection needs to be properly connected to a solid
ground. See the figure below.
Figure 8. Earth connection
4.3. Cooling
For mounting in 19" apparatus cabinet without forced ventilation, a minimal spacing of 1U
according to IEC 60297 or 45 mm (1.75") above/below is recommended. With forced
ventilation, no minimal spacing is required as long as the temperature of the rear cooling
plates does not exceed +85ºC (+185ºF).
For wall mounting in an area without forced ventilation, a minimum spacing of 45 mm
(1.75") above/below and 10 mm (0.4") left/right is recommended. For areas with forced
ventilation, no minimal spacing is required as long as the temperature of the rear cooling
plates does not exceed +85ºC (+185ºF).
