Product Information
The EN50155 certified and cyber-hardened managed PoE switches, ITR-AG804TM-8PHE24i and ITR-AG804TM-8PHE-WVi, deliver reliable, high-speed connectivity for rolling stock environments. They feature 12 Gigabit M12 X-code Ethernet ports that ensure secure and stable connections even under vibration and shock conditions. With Layer 3 routing capabilities, including IPv4/IPv6 static routing, RIP v1/v2, and OSPF v2/v3 dynamic routing, the switches enable flexible network segmentation and optimized data traffic management.
Compliant with the IEC 62443-4-2 cybersecurity standard, the ITR-AG804TM series ensures the security and stability of onboard and train-to-ground communications. This compliance strengthens protection against cyber threats and enhances the overall resilience of intelligent railway systems. In addition, the switches support ring redundancy to ensure reliable network failover and prevent system downtime caused by single-point failures.
The series also supports advanced PoE management functions, including auto power detection, intelligent power reset, and scheduling, improving energy efficiency and device uptime. With isolated 24/48 VDC or 24/48/72/96/110 VDC power inputs, the design supports voltage boosting to ensure stable PoE operation across diverse vehicle power systems. Certified to EN 50155 standards for temperature, voltage fluctuation, surge, ESD, vibration, and shock, the ITR-AG804TM series delivers long-term reliability in mission-critical rail and vehicle applications.
