Frequently Asked Questions
What is EN50155 compliance and why does it matter for railway switches?
EN50155 is the European standard for electronic equipment used on railway rolling stock. Compliance ensures the switch meets stringent requirements for reliability, safety, and performance in mobile railway environments. The Advantech EKI-9516G's EN50155 certification guarantees it will perform reliably in demanding railway applications with minimal maintenance.
How many devices can the 150W PoE budget support?
The 150W PoE power budget can support multiple connected devices depending on individual power consumption. Typical industrial PoE devices draw 30–95W, allowing the switch to power 2–5 devices simultaneously. Consult device specifications and use network planning tools to optimize your deployment.
Is the EKI-9516G suitable for outdoor wayside installations?
Yes. The IP67-rated rugged housing protects against dust, rain, and moisture ingress, making it ideal for outdoor wayside equipment cabinets and trackside installations. The wide 24–110 VDC power input range also accommodates diverse power sources common in railway infrastructure.
What does X-Ring Pro provide for network reliability?
X-Ring Pro enables rapid network convergence (typically under 200ms) when topology changes occur, such as cable failures or device disconnections. This minimizes service interruptions and ensures continuous connectivity for critical railway control and monitoring systems.
