Description

The Moxa TN-4908-ETBN-4GTX-4GTXBP-WV-T is an EN 50155 rolling-stock secure router with IEC 61375 ETBN functionality for train backbone networks. It provides eight Gigabit Ethernet M12 X-coded ports, four standard GTX and four GTXBP with bypass relays, and runs on a redundant 24 to 110 VDC input across a -40 to 70 °C operating range. This variant has no PCB conformal coating.

Built in an IP40 metal housing for wall mounting, the TN-4900 Series router supports routing with RIP and OSPF, NAT, IPsec and L2TP VPN, and TRDP. Turbo Ring v2, RSTP/STP and VRRP provide network redundancy, and the unit is compliant with EN 50155, EN 50121-4, EN 45545-2 and IEC 61373 for onboard railway deployments.

FAQs

Q: Does the TN-4908-ETBN-4GTX-4GTXBP-WV-T include a firewall?
A: No. This is the ETBN model without a firewall. Moxa offers a separate -F variant for firewall functionality.

Q: How many ports have bypass relays?
A: Four of the eight Gigabit M12 X-coded ports are GTXBP ports with bypass relays. The other four are standard GTX ports.

Q: What power input does this router accept?
A: It accepts redundant dual 24/36/48/72/96/110 VDC inputs on M12 K-coded connectors, with an operating voltage range of 16.8 to 137.5 VDC.

Q: Does this model have PCB conformal coating?
A: No. The -T model has no conformal coating, unlike the -CT-T sibling.

Q: What railway standards does it meet?
A: It complies with EN 50155, EN 50121-4, EN 45545-2 and IEC 61373, and provides IEC 61375-2-3 and 61375-2-5 ETBN functionality.

Q: What redundancy protocols are supported?
A: The router supports RSTP, STP, Static Port Trunk, Turbo Ring v2 and VRRP.
