3. Product Description

3.1. Product Description

RedFox 5728 takes communication reliability for substations to a new level. Westermo understands that in critical substation automation applications, even the loss of a single piece of data can disturb the operations, and that is why RedFox 5728 brings the highest reliability to your network. Withstanding the toughest environmental conditions, including the high EMI levels derived from load switching and lightning strikes and extreme ambient temperatures, RedFox-5728 ensures 100% uptime, no matter what.

IEC 61850-3 and IEEE 1613 standards define the requirements and test levels for networking devices. They specify two different device reliability classes: Class 1 devices, which allow for communication errors; and Class 2 devices, which do not allow loss of a single transmission package even during the highest electro magnetic disturbances (EMI). RedFox 5728 meets or exceeds all test levels for Class 2 fulfilment, attaining KEMA type test gold certification, ensuring zero down-time, communication losses, delays or errors.

Superior build quality, the exclusive use of industrial grade components and extensive in-house testing results in class-leading MTBF and extended service life. Designed to run efficiently from either one or two power inputs, with dual internal power supplies fully isolated from each other and all other interfaces. The 28-port switch has all connectors located at the front for easy access and a range of different port configurations, customizable with SFP transceivers.

For resilient operations in substations not only is the most robust hardware needed, but also the most robust software. Available with both layer 2 and layer 3 functionality, RedFox 5728 is powered by the next generation WeOS operating system, which ensures continuous operation and support for an expanding range of protocols and features. Intuitive set-up and configuration enable easy and cost-efficient installation and removes the need for specialized IT support or training.
