AirPort Extreme Setup Guide

Plugging In Your AirPort Extreme

Before you plug in your AirPort Extreme, rst connect the appropriate cables to the ports you want to use:

• Connect the Ethernet cable that’s connected to your DSL or cable modem (if you’ll connect to the Internet) to the Ethernet WAN port (<) .

• Connect a USB cable from the USB port (d) on your AirPort Extreme to a compatible USB printer, a hard disk, or a hub.

• Connect an Ethernet cable from any Ethernet device to any of the Ethernet LAN ports (G). After you connect the cables for all the devices you plan to use, connect the power cord to the power port and plug your AirPort Extreme into a power outlet. There is no power switch.

   

  Important: Use only the power cord that came with your AirPort Extreme.

   

  When you plug the AirPort Extreme power cord into a power outlet, the status light glows amber during startup, and then ashes amber during setup. The status light glows green after your AirPort Extreme is set up and connected to the Internet or a network.

   

  When you connect Ethernet cables to the Ethernet ports, the lights above them glow solid green.
