Westermo launches managed Ethernet switch series for the most demanding substation automation applications

RedFox-5728 creates resilient data communications networks to ensure reliable substation operations.

Westermo has introduced a new line of managed industrial Ethernet switches designed to provide extremely resilient data communications networks in the most demanding substation automation applications. Assured network availability and zero data loss are essential to prevent disruption to power distribution operations. The RedFox-5728 switch meets these requirements by operating and delivering the most resilient networks in extreme substation environments.

The RedFox-5728 is capable of withstanding the harshest environmental conditions, including high levels of electromagnetic interference generated by load switching and lightning strikes and extreme ambient temperatures. IEC 61850-3 and IEEE 1613 standards define the requirements and testing levels for network equipment in these applications. The RedFox-5728 meets or exceeds all test levels for Class 2 compliance, which does not allow the loss of a single transmission packet even at the highest EMI bursts. The switch has also earned KEMA Gold Type Test Certification, which ensures zero dropouts, loss of communications, delays or errors.

Excellent build quality, exclusive use of industrial-grade components and extensive in-house testing result in best-in-class Mean Time Between Failure (MTBF) and extended life. The RedFox-5728 has been designed to operate effectively from either one or two power inputs, with the two internal power supplies fully isolated from each other and from all other interfaces, preventing failures in the event of a fault. This 28-port switch is suitable for installation in a 19" rack, with all connectors located on the front for easy access and a variety of different port configurations that can be customized with SFP transmitters.

Low power substation operations require robust hardware and software. The RedFox-5728 switch, available with both Layer 2 and Layer 3 features, is powered by the next generation WeOS operating system to ensure continuous operation and support for an expanding range of protocols and features. Intuitive setup and configuration make installation easy and cost-effective, eliminating the need for specialized IT support or training. With the increasing sophistication of cyber attacks, an extensive suite of cybersecurity tools is available.</p

"Substations represent one of the most hostile environments for network technology, and these automation applications also require the highest level of network reliability," explained Henrik Jerregård, senior product manager at Westermo. "The RedFox-5728 not only meets but exceeds the requirements for these applications, helping to provide operators with peace of mind. With RedFox-5728, the reliability of substation data networks is assured."
