Introduction
The ToughNet TN-5308-4/8PoE series M12 unmanaged Ethernet switches are designed for industrial applications in harsh environments. The M12 connectors ensure tight, robust connections,and guarantee reliable operation, even for applications that are subject to high vibration and shock. The TN-5308-4/8PoE series Ethernet switches provide 8 fast Ethernet M12 ports with 4/8 IEEE 802.3af compliant PoE (Power-over-Ethernet) ports. The switches are classified as power source equipment (PSE) and provide up to 15.4 watts of power per port.
The TN-5308-4/8PoE switches can be used to power IEEE 802.3af compliant powered devices (PDs), eliminating the need for additional wiring. The switches support IEEE 802.3/802.3u/802/3x with 10/100M, full/half-duplex, MDI/MDI-X auto-sensing, and provide an economical solution for your industrial Ethernet network. Models with an extended operating temperature range of -40 to 75°C are also available. The TN-5308-4/8PoE switches are compliant with EN50155/50121-4 making them suitable for a variety of industrial applications.
White Paper: Optimized Ethernet Redundancy for Inter-Consist Networks 
Network redundancy is a critical factor in ensuring passenger safety and journey reliability in onboard railway communications for both intra-consist and inter-consist Ethernet networks. In addition, railway operators are looking for ways to more efficiently allocate resources and serve passenger demands. For example, metropolitan rail services may want to run trains with fewer consists during off-peak hours but longer trains with more consists during rush hour. Railway operators can also serve multiple markets and conserve track assets by connecting multiple consists with different destinations into one train if they will travel along the same route for at least part of the journey.
This white paper describes how Dynamic Ring Coupling helps railway operators provide seamless onboard Ethernet redundancy with both rapid recovery times and automatic Ethernet switch configuration even when consists are rearranged mid-journey.
