The TN-G4516-8GPoE-2XGPoE-2XGTXBP-WV-CT-T is a next-generation EN 50155-compliant managed M12 Ethernet switch with conformal coating, providing additional protection against dust, humidity, salt mist, and chemical corrosion. This makes it an ideal choice for harsh rolling stock and outdoor railway environments where long-term reliability is critical.
Equipped with 2× 10G PoE ports, 2× 10G copper bypass ports, 8× Gigabit PoE ports, and 4× Gigabit copper ports, the switch delivers robust multi-Gigabit connectivity. Its IEEE 802.3af/at PoE+ support allows each powered port to provide up to 30 W, with a total PoE budget of 120 W, ensuring seamless power for IP surveillance, train communications, and wireless services. The bypass relay on the 10G copper interfaces maintains data flow during outages, safeguarding critical network uptime.
The unit supports a wide 24–110 VDC isolated dual input range, ensuring dependable operation across varied railway power systems. Compliance with EN 50121-4, IEC 61373, and EN 45545-2 provides EMC performance, shock/vibration resistance, and fire safety assurance. An IP40-rated housing and a wide operating range of -40 to 70°C ensure resilience in extreme climates.
Moxa’s Turbo Ring and Turbo Chain redundancy deliver sub-50 ms failover recovery across large networks, while compatibility with STP/RSTP/MSTP ensures standards-based interoperability. Security features include HTTPS, SSH, TACACS+, RADIUS, IEEE 802.1X, and port locking to prevent unauthorised access.
The TN-G4516-8GPoE-2XGPoE-2XGTXBP-WV-CT-T blends high-speed performance, PoE versatility, redundancy, and conformal coating durability—making it a trusted backbone switch for mission-critical railway and transportation communications.
