Xerxes Nano Carrier Board for Jetson Orin Nano Super and Turing RK1 Modules · File : jetson-orin-poe-ethernet-monitor-6.ino · Language : Bash · Use case : Surveiller la connexion Ethernet Gigabit via PoE et vérifier l'état du lien physique.

Checks the status and link speed of the Gigabit Ethernet RJ45 interface, crucial for PoE-powered deployments.

The Xerxes Nano board uses the native Ethernet controller of the Jetson module. Run this script after connecting an RJ45 cable to the PoE-compatible port. Ensure the power jumper is configured for PoE if USB is not connected. The script reads sysfs files directly for a quick response without external dependencies.
