Congratulations on purchasing your AirPort Extreme Base Station.
Read this guide to get started.
AirPort Extreme is a fully featured Wi-Fi base station that provides simultaneous dual-band
wireless networking using the 802.11ac specication. When you set up your AirPort Extreme, it
creates two high-speed Wi-Fi networks:
 A 2.4 gigahertz (GHz) network for 802.11b, 802.11g, and 802.11n devices, such as iPhone,
iPod touch, and older computers
 A 5 GHz network for 802.11n, 802.11a, and 802.11ac devices, such as iPhone, iPad, Apple TV,
and newer computers
Wi-Fi devices automatically join the network that provides the best performance and
compatibility, and AirPort Extreme shares your broadband Internet connection with computers
and devices on your network.

Plugging In Your AirPort Extreme
Apple Confidential
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.
