FAQs

Q: What does the bypass relay do on this router?
A: Four of the Gigabit M12 X-coded ports include a bypass relay, which keeps the train backbone link connected through the device if power is lost.

Q: What power supply does the TN-4908-ETBN-F-4GTX-4GTXBP-WV-CT-T need?
A: It has redundant dual DC inputs for 24/36/48/72/96/110 VDC nominal, with an operating range of 16.8 to 137.5 VDC, via an M12 K-coded connector.

Q: Is this unit suitable for rail rolling stock?
A: Yes. It complies with EN 50155 and EN 45545-2, supports IEC 61375 ETBN and TRDP, and withstands railway shock and vibration requirements per IEC 61373.

Q: What VPN capability does it offer?
A: It supports IPsec with up to 250 tunnels using AES, 3DES and SHA-256, plus an L2TP server.

Q: Does it have a conformal coating and what temperature range does it support?
A: Yes. The PCB is conformal coated and the unit operates from -40 to 70°C.

Q: How is it mounted?
A: It is wall mounted and housed in an IP40 rated metal enclosure measuring 160 x 115 x 70 mm.
