Connecting to an Ethernet Network
Your computer comes with built-in 10/100/1000 megabit per second (Mbps) twisted-pair
Ethernet networking capability. Connecting to a network gives you access to other
computers. You may be able to store and retrieve information; use network printers,
modems, and electronic mail; or connect to the Internet. You can also use Ethernet to share
files between two computers or set up a small network.
If you’re connecting to an existing network, you may be able to get information about the
network and the network software you need from a network administrator who oversees its
operation. Identify your organization’s network administrator before you begin.
Follow these guidelines when selecting a cable for your network:
Connecting to a Twisted-Pair Ethernet Network
You can connect directly to a 10/100/1000 twisted-pair Ethernet network.
Note: You can also connect your computer to an Ethernet network that uses thin coaxial cables.
To do this, you need an RJ-45–to–Thin Coax adapter (available from other manufacturers). See
your Apple-authorized dealer for more information on Ethernet media adapters.
To connect your Macintosh to a centralized 10/100/1000 twisted-pair Ethernet network,
follow these steps:
1 Plug one end of an RJ-45 twisted-pair cable into the Ethernet port on your Macintosh.
