Industrial routing switch


RedFox is designed for industrial application with many functions designed for easy use. The high bandwidth design allows for up to 8 Gbit ports as well as having other ports that can deliver 10/100 Mbit. The RedFox is powered by WeOS (Westermo Operating System) which is our cross platform solution providing strong future proofing and ease of use.

In RedFox the design of the electronics is critical to ensure long service life in extreme operating environments. Only industrial grade components are used which gives the RedFox an MTBF of 600 000 hours. The ultra robust RedFox has a heavy-duty aluminium enclosure for maximum strength and heat dissipation ensuring that the wide temperature range –40 to +70°C (–40 to +158°F) can be achieved with no moving parts or cooling holes in the case.

RedFox has been tested both by Westermo and external test houses to meet many EMC, isolation, vibration and shock tests, all to the highest levels suitable for heavy industrial environments and rail trackside application.

WeOS is a Layer 3 switch operating system that can deliver unique IP security functionality for this class of product, for instance a Multiport DMZ can be constructed by utilising the internal port based firewall function. Remote secure access to a network can be provided using encrypted VPNs.

For more WeOS functionality please see the WeOS datasheet.
