*Connect a cable to the RJ45 jack. We assume that a DHCP server is running in your network.<br />
*If you have set a valid MAC address in Redboot already, you will see that the board gets its IP address automatically during Linux boot:<br />

== Set the MAC address (Linux) ==<br />
<br />
*Show the current MAC address:<br />
ifconfig -a|grep eth0<br />
Look for "HWaddr"<br />
<br />
*Change the MAC address to 00:01:02:03:04:05:<br />
ifconfig eth0 hw ether 00:01:02:03:04:05<br />
<br />
== Set the MAC address (Redboot) ==<br />
<br />
You can setup Redboot to automatically assign a MAC address of your board at boot. Use the ''fconfig'' command for configuration.<br />
We will assign the address ''02:03:04:05:06:07'' here.<br />
<br />
RedBoot> fconfig -l<br />
...<br />
Set FEC network hardware address [MAC]: true<br />
FEC network hardware address [MAC]: 0x02:0x03:0x04:0x05:0x06:0x07<br />
...<br />
<br />
Don't forget to save this configuration at the end of ''fconfig''.<br />
