AirPort Wir eless Networking
The iMac, iMac DV, and iMac DV Special Edition computers
support wireless networking using the optional AirPort
wireless networking card. To participate in wireless
networking, the system must have the following:
• internal antenna - The antenna necessary for wireless
networking is already installed inside the iMac computer.
• AirPort Card - This small card (about the size and shape
of a credit card) can be installed in the wireless
networking slot inside the computer. Users can purchase
cards from an Apple-authorized dealer or from The Apple
Store.

In addition, to access another computer network or Internet
service provider, users need to connect a wireless access
device to their network. This access can be an AirPort Base
Station (a stand-alone hardware product with a wireless
antenna and network/modem connections) or an AirPort
Software Base Station (software running on a wirelessequipped computer).
FireWire
FireWire is a high-speed data system that lets you easily
connect and disconnect external devices—such as digital
video (DV) cameras, printers, scanners, and hard disks
without restarting your computer. The better and best iMac
configurations include two external FireWire ports on the
side panel.

VGA Output Port
The iMac DV and iMac DV Special Edition computer includes a
port for an external video monitor, so you can mirror, or
show, what’s on the computer display to a larger audience.
The external monitor supports only the display sizes that
are available on the internal monitor.
The connector for the video monitor is a three-row HD15
connector (DB9/15, also called mini sub D15) for use with
a VGA, SVGA, or XGA monitor.

This chapter contains basic theory of operations information as
well as detailed Symptom/Cure tables, both of which should help
you troubleshoot and repair the iMac, iMac DV and iMac DV
Special Edition systems.
The Symptom/Cure tables are broken down into two sections:
problems that can occur at startup time-before the Finder
appears on the screen; and problems that can occur after a
successful startup. Each major symptom has its own symptom/
cure table.
In the left-hand column of each table are the possible causes of the
symptom, with the corresponding cures in the right-hand column.
You should also follow the tables in the order presented as they
represent the most logical order for cause and cure. Verify
