Using the Time Capsule
This section describes the different network interfaces of the Time Capsule and
describes the functions it can provide.
Time Capsule Interfaces
To use your Time Capsule, you configure how its networking interfaces will be used.
The Time Capsule has five hardware networking interfaces:
 AirPort interface: The AirPort interface creates an AirPort network for AirPort-
enabled computers to join. The Time Capsule can provide IP services such as DHCP
and NAT using this interface. The Time Capsule cannot use the AirPort interface to
establish a connection with the Internet.
 Ethernet WAN (<) interface: Use the Ethernet WAN interface to connect DSL
or cable modems and connect to the Internet.
 Ethernet LAN (G) interface: The Time Capsule has three Ethernet LAN interface
ports. You can use them to provide IP services to local Ethernet clients.
 USB (d) interface: Use the USB interface to connect a USB printer to the Time
Capsule.
Using the AirPort Express
This section describes the different network interfaces of the AirPort Express Base
Station and describes the functions the base station can provide.
AirPort Express Interfaces
To set up the AirPort Express Base Station, you configure how its networking interfaces
will be used. The AirPort Express Base Station has four hardware networking interfaces:
 AirPort interface: The AirPort interface creates an AirPort network for AirPort-
enabled computers to join. The base station can provide IP services such as DHCP
and NAT using this interface. The base station cannot use the AirPort interface to
establish a connection with the Internet.
 Ethernet WAN (<) interface: Use the Ethernet WAN interface to connect DSL
or cable modems and connect to the Internet.
 USB (d) interface: Use the USB interface to connect a USB printer to the
AirPort Extreme Base Station.
