The TN-G4516-8GPoE-4XGPoE-WV-T is a high-performance EN 50155 Layer 2 managed Ethernet switch engineered for railway and transportation networks. Designed with rugged M12 connectors, it delivers vibration- and shock-resistant connectivity, ensuring reliable operation in the harshest rolling stock and wayside environments.
Equipped with 4× 10G PoE ports, 8× Gigabit PoE ports, and 4× Gigabit copper ports, the switch provides advanced multi-Gigabit performance for bandwidth-hungry applications such as CCTV surveillance, on-board infotainment, and real-time control systems. With support for IEEE 802.3af/at PoE+, each port can deliver up to 30 W of power, with a total PoE budget of 120 W, making it ideal for powering IP cameras, access points, and other edge devices without separate power lines.
The unit operates across a wide 24–110 VDC input range with dual isolated power supplies for redundancy. Compliance with EN 50155, EN 50121-4, IEC 61373, and EN 45545-2 ensures suitability for railway deployment, covering shock, vibration, fire protection, and EMI/EMS immunity. Its IP40-rated metal housing and extended -40 to 70°C operating temperature range further enhance reliability.
Network resilience is assured through Moxa’s Turbo Ring and Turbo Chain technology with sub-50 ms recovery for up to 250 nodes, alongside STP/RSTP/MSTP support. Advanced security features include IEEE 802.1X, RADIUS, TACACS+, HTTPS, SSH, and port lock, while management protocols such as SNMPv3, RMON, LLDP, and VLAN provide full visibility and control.
The TN-G4516-8GPoE-4XGPoE-WV-T combines high-speed data, power delivery, and robust design, making it a reliable backbone for mission-critical railway Ethernet systems.
