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.
