As global rail operators accelerate their investment in passenger digitalization-spanning onboard Wi-Fi, infotainment, and real-time passenger information-deploying robust, high-density networking infrastructure has become a strategic imperative.

Introducing the Advantech EKI-9520G Series: an EN50155-certified Layer 2, 20-port Ethernet switch designed specifically to handle the demanding requirements for modern railway comfort and operational networks.

Thermal Monitoring
Lorem Ipsum is simply dummy text of the printing and typesetting industry.

Railway Certified
Fully compliant with EN 50155, EN 45545-2 (Fire Prevention), and EN 61373 (Shock and Vibration).

Cybersecure
Designed to meet IEC 62443-4-2 standards.

Within each train consist, the EKI-9520G serves as the ECN core switch, connecting the ETB backbone to onboard systems such as PIS, PA, CCTV, HVAC, and Wi-Fi APs ? with built-in PoE that directly powers cameras and speakers.
