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 4x 10G PoE ports, 8x Gigabit PoE ports, and 4x 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.
