Info

Ethernet interface allow the connection of the Archimede board to a LAN (Local Area Network) and to the Internet.

Pinout

Archimede has one RJ45 interface supporting Fast Ethernet 10/100Mbit. Each Archimede has assigned a unique 48-bit MAC address stored in EEPROM memory. The default linux system is set up to have Ethernet interface enabled and to get an IP address automatically from the network via DHCP.

Also Ethernet interface can be powered off for energy saving. For info about how to power on and off the interface see —LINK A UNA PAGINA DEDICATA—

Check status of Ethernet interface:

The connection status is indicated by two LEDs built-in connector:

• green – (LINK – LED) is on when a valid link is detected. LED blinks when transmit or receive activity is detected.
• yellow – (SPEED – LED) is on when the Ethernet operating speed is 100Mbs, or during auto-negotiation. LED is off during 10Mbs operation, or during line isolation.

To check the status of the interface from linux shell you can use

$ ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:50:c2:b7:70:00
