Chapter 1  Getting Started

Before you plug in your AirPort Express, first connect the appropriate cables to the ports you 
want to use—including:

 Â

An Ethernet cable connecting your DSL or cable modem to the WAN port (if you’ll connect 
to the Internet)

 Â

An audio cable connecting your stereo to the audio out port (if you’ll use AirPlay to play 
music from your iTunes library)

 Â

A USB or Ethernet cable connecting a printer to the USB or Ethernet port (if you’ll print to it 
using AirPort Express)

After you connect the cables for all the devices you plan to use, plug the AirPort Express 
power cord into the power port and a power outlet. There‘s no on/off switch. 
When you plug the AirPort Express power cord into a power outlet, the status light glows 
amber during startup, and then flashes amber during setup. The status light glows green after 
your AirPort Express is set up and connected to the Internet or a network. 

The following table describes AirPort Express status light sequences and what they indicate.
