6 Chapter 1 Introduction to AirPort
The AirPort Extreme Base Station has the following ports:
 10/100Base-T Ethernet WAN port (< ) for connecting a DSL or cable modem, or for
connecting to an existing Ethernet network with Internet access
 10/100Base-T Ethernet LAN port (G ) for high-speed connection to local printers and
Ethernet computers that don’t have Internet access
 USB port (d ) for connecting a printer to the base station
Some models of the base station also have a built-in 56K modem port (W ) for dial-up
Internet access with a standard telephone line.
Some models of the base station can also receive power over Ethernet (PoE). When the
base station Ethernet WAN port is connected to IEEE 802.3af-compliant Power Sourcing
Equipment (PSE), such as a line-powered Ethernet switch or hub, with a CAT 5 Ethernet
cable, it receives power over the Ethernet cable. Look on the bottom of the base
station to see if it supports PoE.
