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 reseller or search the Macintosh Product Guide for more information on Ethernet media adapters.
To connect your Macintosh to a centralized 10/100/1000 twisted-pair Ethernet network, follow these steps:

To connect your Macintosh to a centralized 10/100/1000 twisted-pair Ethernet network, follow these steps:
- Plug one end of an RJ-45 twisted-pair cable into the Ethernet port on your Macintosh.
- Plug the other end of the cord into an RJ-45 wall outlet or external hub that is connected to a twisted-pair Ethernet network (Figure 1). After you start up the computer, you need to configure the software for your network connection. Your network administrator can provide the necessary information. You can also get help configuring your network software using Mac Help (in the Help menu).
A basic twisted-pair network
To configure your network settings:
- Choose System Preferences from the Apple menu, then choose Network from the View menu.
- Show Built-in Ethernet.
- Click the TCP/IP tab and enter information about your network. The default setting is Configure Using DHCP.
- Click Apply Now.
- Close System Preferences.
