Expanded the Industrial device type library in the netbox-community/devicetype-library repository by adding detailed specifications for EtherWAN, Phoenix Contact, and Palo Alto industrial network devices. This work focused on enhancing data modeling and device management using YAML, ensuring each new device entry included comprehensive manufacturer, model, interface, and power port information. The approach improved inventory accuracy and streamlined the onboarding process for industrial devices, supporting better integration and maintainability across the library. Collaboration was demonstrated through a co-authored commit, and the technical effort addressed both the expansion and reliability of device entries, leveraging skills in networking and structured data representation.
