The TN-G4500 Series is a new generation of EN 50155-certified managed Ethernet switches designed for mission-critical railway networks, including both rolling stock and wayside deployments. Featuring rugged M12 connectors for shock- and vibration-proof cabling, the series delivers 4x 10G high-speed uplinks alongside 12x Gigabit ports, with options for up to 12x PoE+ outputs supplying 30 W per port and a total PoE budget of 120 W. This allows operators to power cameras, access points, and intercoms directly from the switch, reducing cabling complexity.
The TN-G4500’s robust hardware is tailored for harsh railway environments, with dual isolated 24–110 VDC inputs, IP40-rated metal housing, and support for -40 to 70°C operation. Specific models feature bypass relay capability on 10G copper interfaces, ensuring uninterrupted traffic during unexpected power loss. Optional conformal coating further protects against moisture, dust, and corrosive atmospheres.
Advanced redundancy is built in with Turbo Ring and Turbo Chain, ensuring recovery under 50 ms across large topologies, with full support for STP/RSTP. Enhanced management is provided through SNMPv3, RMON, LLDP, and VLANs, while integrated security includes TACACS+, RADIUS, HTTPS, SSH, and IEEE 802.1X port-based control. IGMP snooping, QoS, and VLAN partitioning improve traffic determinism, while diagnostic features such as port mirroring, loop protection, and email/relay alarms simplify troubleshooting.
Fully compliant with EN 50155, EN 50121-4, EN 45545-2, and IEC 61373, the TN-G4500 Series meets the stringent EMC, fire, vibration, and shock requirements of railway applications. Its wide feature set, resilient design, and flexible port mix make it the ideal backbone switch for modern train communication and onboard IP systems.
