2.5.2 Ethernet Interface

BeagleBone Green Eco provides a 10-,100-, 1000Mbps Ethernet interface for network connectivity, terminated with an RJ45 connector. This interface allows direct connection to local networks through standard Ethernet cables.

The Ethernet port features integrated link and activity indicator LEDs – a green LED showing established link status and a yellow LED indicating active network traffic. These visual indicators help users quickly determine network connection status.

The interface supports standard network protocols and services, including Dynamic Host Configuration Protocol (DHCP) for automatic IP address acquisition and static IP configuration. The Ethernet implementation of the board is compatible with common networking tools and utilities found in Linux® distributions.

For developers, the Ethernet interface can be accessed through standard Linux networking commands and APIs. The Common Platform Ethernet Switch (CPSW) subsystem of the processor provides efficient packet processing, enabling reliable network performance for various applications.

The Ethernet port supports Wake-on-LAN functionality, allowing remote power management when properly configured in the operating system. This feature can be useful for headless applications where remote access is needed without physical interaction.

When connecting to networks, standard CAT5e or better Ethernet cables are recommended for the best performance, particularly when utilizing the gigabit capabilities of the interface.
