Introduction

The ToughNet TN-4900 Series, designed for rolling stock Ethernet networks, is a set of high-performance M12 routers with 8 Gigabit ports and up to four bypass relay ports. These routers feature firewall, ETBN, and routing functionality to facilitate the deployment of applications across networks. The TN-4900 Series routers use M12 and other circular connectors to ensure tight, robust connections that guarantee reliability against environmental disturbances, such as vibration and shock.

The TN-4900 Series supports a wide power input range of 24 to 110 VDC and can operate in temperatures of -40 to 70°C for extended periods of time. Furthermore, these routers are compliant with the mandatory requirements of EN 50155, making them suitable for a variety of industrial applications.

Additional Features and Benefits

  • IEC 61375-2-3, 61375-2-5–compliant ETBN

  • Routing functionality to divide a large network into hierarchical subnets and allow data and information to communicate across networks

  • NAT makes IP management easier as end devices in different carriages can use the same IP addresses

  • Leading EN 50155 Ethernet router for rolling stock applications

  • Turbo Ring and RSTP/STP for network redundancy

  • Wall mounting installation

  • Line-swap fast recovery

  • Automatic recovery of connected device’s IP addresses

  • LLDP for automatic topology discovery in network management software

  • Configurable by web browser, Telnet/serial console, and CLI Windows utility

  • IPS/ IDS threat detection and protection are supported on models with firewall function (license is required)

IEC 62443-4-2 Security Level 2 Certified

TN-4900 Series models with a firewall (HW Rev. 3.0) are IEC 62443-4-2 Security Level 2 certified (https://certificates.iecee.org/#/deliverables/CERT/1672424/view), enhancing cybersecurity in industrial networks.
