The EOTec 2104 is a rugged, high performance Industrial Ethernet ring switch that is designed to fill the gap between unmanaged and managed Ethernet switches. It provides all the benefits of redundant ring topology operation, but at a significantly lower cost than managed switches. The 2104 features the simplicity of installation and operation of an unmanaged switch, while retaining many of the capabilities of a managed switch. It is pre-configured for ring topology and no setup or configuration is required. It doesn’t require master switch selection or an IP address to operate in a redundant ring topology. Its ultra fast link loss recovery time ensures high reliability with minimal downtime.
