Congratulations on purchasing your new highperformance Power Mac G5 computer. This chapter
contains instructions for setting up your computer
and display.
Your Power Mac G5 features the latest computer technology, including advanced 64-bit
dual core processor technology, high-speed DDR2 memory, PCI Express graphics and
expansion cards, and Serial ATA internal storage, all in an anodized aluminum chassis
with easy access to internal components.
Setting Up Your Power Mac G5
Your Power Mac G5 is designed so that you can set it up quickly and start using it right
away. Follow the steps on the next few pages to set up your Power Mac G5.
Before you begin, remove any protective film from the outside of your computer and
from the inside of the side panel. For instructions about opening the side panel, see
“Opening the Computer” on page 46.

Step 1: Position your computer and display
Pick up the computer by both of its handles using correct lifting techniques. If your
display is heavy, use correct lifting techniques when positioning it as well. Position the
computer and display so that:
 They are on sturdy, flat surfaces
 The power cable connectors don’t press against a wall or other object
 The airflow in front of, behind, or below the display or computer is not obstructed
 The computer’s optical drive tray has space to open in front
Warning: Apple recommends that you operate your Power Mac G5 in an upright
position with the side panel in place. The computer does not operate properly when
it is placed on its side or when the side panel is removed.
The only way to shut off power completely to your computer and display is to
disconnect their power plugs from the power source. Make sure the power cords for
your computer and display are within easy reach so that you can unplug the computer
or display when you need to.
Step 2: Plug in the power cord
Plug the power cord firmly and completely into the recessed power cord socket on the
back of the computer and plug the other end into a grounded outlet or a grounded
power strip.

Need Help Setting Up?
If you don’t see anything on your screen or you think your computer did not start up
properly, check the following:
 Is the computer plugged into a power source? If it’s plugged into a power strip, is the
power strip turned on?
 Is the power cord securely plugged into the back of the computer?
 Are the keyboard and display cables connected correctly?
 Is the display turned on? Are the brightness and contrast controls on the display
adjusted correctly? If your display has brightness and contrast controls, adjust them.
 If you still don’t see anything on your screen, restart your computer. Press and hold
the computer’s power button for approximately 5 seconds until the computer turns
off. Press it again to turn on the computer.
 If you see a blinking question mark on the screen or see a series of flashes from the
status light when you turn on the computer, see Chapter 5, “Troubleshooting,” on
page 69.
Next Steps
The first time you turn on your computer, Setup Assistant starts. Setup Assistant helps
you enter your Internet and email information and set up an account on your
computer. If you have another Mac, Setup Assistant can also help you transfer files,
applications, and other information from your old Mac to your new Power Mac G5.
Transferring Information to Your Power Mac G5
You can use Setup Assistant to automatically transfer information from another Mac to
your new Power Mac G5. To transfer information, make sure of the following:
 Your other Mac must have built-in FireWire and support FireWire Disk Mode.
 Your other Mac must have Mac OS X v10.1 or later installed.
 You must have a FireWire cable to connect the two computers.
Setup Assistant takes you through the process of transferring your information—just
follow the onscreen instructions. Transferring information to your Power Mac G5 does
not affect the information on your other Mac. You can transfer:
 User accounts, including preferences and email
 Network settings so that your new computer is automatically set up to work with
the same network settings as your other Mac
 The Applications folder so that the applications you used on your other Mac are
now on your new Power Mac G5 (you may have to reinstall some of the applications
you transfer)
 Files and folders stored on your hard disk. This gives you easy access to the files and
folders you used on your old Mac.
10
Chapter 1 Getting Started
If you don’t use Setup Assistant to transfer information when you first start up your
Power Mac G5, you can do it later using Migration Assistant. Open the Applications
folder, open Utilities, and double-click the Migration Assistant icon.
Note: If you transfer information later using Migration Assistant, make sure FileVault is
turned off on the older computer. To turn off FileVault, choose Apple () > System
Preferences, click Security, and follow the onscreen instructions.
Setting Up Your Power Mac G5 to Connect to the Internet
If you didn’t transfer your user account and network settings information, Setup
Assistant takes you through the process of configuring your Power Mac G5 and setting
it up to connect to the Internet. For home users, Internet access requires an account
with an Internet service provider (ISP) and fees may apply. If you have an Internet
account, see Appendix C, “Connecting to the Internet,” on page 89 for information
you’ll need to enter.

Adding PCI Express Cards
You can expand the capabilities of your Power Mac G5 by installing cards in the
Peripheral Component Interconnect (PCI) Express slots. Your Power Mac G5 has four PCI
Express slots that accommodate PCI Express cards and PCI Express graphics cards.
About PCI Express Cards
Your Power Mac G5 comes with a high-performance 16-lane (or 16x) PCI Express
graphics card. This card, which contains the graphics processor unit (GPU) and provides
the computer’s display ports, is installed in slot1.
The maximum bus width for each PCI Express slot is marked on the
card guide. Slot 4 is a 4-lane (4x) slot, slot 3 is an 8-lane (8x) slot,
slot 2 is a 4-lane (4x) slot, and slot 1 is a 16-lane (16x) slot.
You can install additional PCI Express cards in any of the slots. Before installing a card,
check the specifications to make sure it can operate in your Power Mac G5.
Important: Combined maximum power consumption for all four PCI Express slots must
not exceed 200 watts (W). The total combined maximum video random access
memory (VRAM) for all graphics cards is 1 GB (for example, you can install one 512 MB
VRAM card and two 256 MB VRAM cards for a total of 1 GB of VRAM).
Although all slots can accommodate PCI Express cards that have up to 16 lanes, if you
install a card that requires a greater bandwidth than the slot provides, the card will
operate at the bandwidth of the slot. For example, an 8x card installed in a 4x slot, will
operate as a 4x card. Refer to the table below.
PCI Express Slot

Chapter 4 Working Inside Your Computer
65
When you install additional cards, install the highest bandwidth card in slot 3. Follow
these guidelines: Install a second PCI Express card in slot 3, a third in slot 4, and a
fourth in slot 2. This takes advantage of the bus bandwidth of each slot.
Installing Your Card
You can install PCI Express graphics and expansion cards in slots 1 through 4.
Note: If it is easier, you can lay your Power Mac G5 down to install PCI Express cards.
Place a soft, clean cloth on the desk or work surface to avoid scratching the work
surface or your Power Mac G5.
To install a PCI Express card:
1 Open the computer and remove the side panel and air deflector (see page 46).
·
Warning: To avoid damaging its internal components or the components you want to
install, always turn off and then unplug your Power Mac G5. Wait 5 to 10 minutes for it
to cool down. Do not attempt to install items inside it while it is plugged in.
2 Remove the screw in the port access cover, pull out the access cover, and set it aside.
Remove the screw that
holds the port access
cover in place.

 Pull the card gently to see if it is properly connected. If it resists and stays in place,
and if its gold connectors are barely visible, the card is connected.
5 Reinsert the port access cover screw and tighten it to hold the card in place.
Warning: If you remove a card and don’t install a replacement, be sure to place a port
access cover over the empty slot to keep foreign objects out of the enclosure. An
uncovered slot affects the airflow that cools the internal components and causes
damage.
6 Replace the air deflector and side panel, following the directions that begin on
page 55.
Chapter 4 Working Inside Your Computer
67
Replacing the Internal Backup Battery
Your Power Mac G5 has an internal backup battery that preserves settings, such as the

Maximizing Ethernet Performance
Your computer performs best when the Ethernet port to which it is connected is set to
auto-negotiate. Ask your network administrator to verify this setting.
Important: If you experience connection problems on your network, make sure your
network switch is set to auto-negotiate, if possible. If a switch’s port is not autonegotiating, your computer detects the appropriate speed but defaults to half-duplex
mode. If the switch’s port at the other end of the link is configured for full-duplex
mode, a large number of late events can occur on the link. If it isn’t possible to set the
switch to auto-negotiate, then set the switch’s port to half-duplex. For more
information, see the documentation that came with the Ethernet switch.
Chapter 5 Troubleshooting

Appendix
B
This appendix provides important information about
safety procedures, routine maintenance, and ergonomic
considerations for using your computer and display.
Important Safety Information
The only way to disconnect power completely from your computer is to unplug the
power cord from the main power supply. To disconnect your display completely, you
must also unplug its power cable from the computer or power outlet. Make sure that at
least one end of the device’s power cord is within easy reach so that you can unplug
the computer or display when necessary.
For your own safety and that of your equipment, always take the following
precautions.
Disconnect the power plug (by pulling the plug, not the cord), from your computer or
display and disconnect the phone cord if any of the following conditions exists:
 The power cord or plug becomes frayed or otherwise damaged
 You spill something into the case
 Your computer or display is exposed to rain or any other excess moisture
 Your computer or display has been dropped or the case has been otherwise
damaged
 You suspect that your computer or display needs service or repair
 You want to clean the computer or display case or screen
 You notice a coolant leak in or from your computer (for Power Mac G5 models
equipped with a liquid cooling system)
83
 If you plan to store your computer for an extended period of time, remove the
battery.
·
Warning: To prevent accidents and damage to your computer or display, be sure that
you always follow these instructions:
Â
Â
Â
Â
Keep your computer and display away from sources of liquids and moisture.
Don’t set anything on top of the computer or display.
Keep the computer and display vents free from obstruction.
Never remove the case from the display or open your computer when it’s running.
You could come in contact with hazardous voltage.
 During lightning storms, disconnect your modem from the phone jack to prevent
damaging the modem with a destructive voltage overload.
Your Macintosh is equipped with a three-wire grounding plug—a plug that has a
third grounding pin. This is a safety feature. Don’t modify the plug to fit into an
ungrounded outlet. Contact a licensed electrician to replace the outlet with a
properly grounded one. Do not defeat the purpose of the grounding plug!
Be careful when lifting or moving your computer or display. Be sure to use correct
lifting procedures, lifting with your legs. When carrying the display, make sure the
display is facing you. Don’t carry the display by its stand. Be careful when lifting or
moving your computer or display. Be sure to use correct lifting procedures, lifting with
your legs. When carrying the display, make sure the display is facing you. Don’t carry
the display by its stand.
Electrical equipment may be hazardous if misused. Operation of this product by
children must always be supervised by an adult. Do not allow children access to the
interior of any electrical product and do not permit them to handle any cables.
Liquid Cooling System
Some Power Mac G5 models use a liquid cooling system to manage the temperature in
the computer. The liquid cooling system is sealed and is designed to be opened only
by an Apple Authorized Service Provider (AASP).
·
84
Warning: Do not attempt to open or service the liquid cooling system. Opening the

Protecting Your Optical Drive
To keep your optical drive working properly:
 Position your computer so that the drive tray doesn’t bump into anything when it
opens.
 Close the drive when you’re not using it.
 Do not put anything on the drive tray when it is open.
 Do not touch the optical drive lens with your fingers. Do not wipe the lens with a
paper towel or other abrasive surface. If you need to clean the lens, see an Apple
Authorized Service Provider for a lens cleaner.
 Keep your computer away from any source of moisture.
Maintaining Your Display
To maintain your display and ensure its long life:
 Do not press on the surface of the display screen.
 Do not write on the screen or touch the screen with a sharp object.
 If you will not be using your display and computer for a day or more, turn off the
computer and display or use Energy Saver.
 Turn off your display, turn down the brightness, or use a screen saver program
that dims or varies the image on the screen when the computer is idle for a
prolonged time.
Important Ergonomic and Health-Related Information
Here are some guidelines for adjusting the furniture in your office to reduce glare and
to accommodate your physical size and shape.
 An adjustable chair that provides firm, comfortable support is best. Adjust the height
of the chair so your thighs are tilted slightly and your feet are flat on the floor.
The back of the chair should support your lower back (lumbar region). Follow the
manufacturer’s instructions for adjusting the backrest to fit your body properly.
 When you use the computer keyboard, your shoulders should be relaxed. Your upper
arm and forearm should form an approximate right angle, with your wrist and hand
in roughly a straight line.
You may have to raise your chair so that your forearms and hands are at the proper
angle to the keyboard. If this makes it impossible to rest your feet flat on the floor,
you can use a footrest with adjustable height and tilt to make up for any gap
between the floor and your feet. Or you can lower the desktop to eliminate the need
for a footrest. Another option is to use a desk with a keyboard tray that’s lower than
the regular work surface.
 Position the mouse at the same height as your keyboard. Allow adequate space to
use the mouse comfortably.
86
Appendix B Safety, Maintenance, and Ergonomics
 Arrange the display so that the top of the screen is slightly below your eye level
when you’re sitting at the keyboard. The best distance from your eyes to the screen is
up to you, although most people seem to prefer 18 to 28 inches (45 to 70 cm).
 Position the display to minimize glare and reflections on the screen from overhead
lights and nearby windows. If possible, use a tiltable display stand. The stand lets you
set the display at the best angle for viewing, helping to reduce or eliminate glare
from lighting sources you can’t move.
45–70 cm (18–28 in.)
Top of the screen at or slightly below
eye level (You may need to adjust the
height of your display by raising or
lowering your work surface.)
Shoulders relaxed
Forearms and hands
in a straight line
Forearms level
or tilted slightly
Screen positioned to avoid
reflected glare
Lower back supported
Clearance under work surface
Feet flat on the floor
or on a footrest
Thighs tilted slightly

ergonomic website at www.apple.com/about/ergonomics.
Avoid Hearing Damage
Warning: Permanent hearing loss may occur if earbuds or headphones are used at
high volume. You can adapt over time to a higher volume of sound that may sound
normal but can be damaging to your hearing. If you experience ringing in your ears
or muffled speech, then stop listening and have your hearing checked. The louder the
volume, the less time required before your hearing can be affected. Hearing experts
suggest that to protect your hearing:
 Limit the amount of time you use earbuds or headphones at high volume
 Avoid turning up the volume to block out noisy surroundings
 Turn the volume down if you can’t hear people speaking to you

Troubleshooting Your Connection
Cable Modem, DSL, and LAN Internet Connections
If you can’t connect to the Internet using your AirPort, built-in Ethernet, or external
modem, you can use Network Diagnostics to diagnose connection problems. Click
“Assist me” in the network pane of System Preferences, click Diagnostics, and follow the
onscreen instructions.
If Network Diagnostics can’t resolve the problem, there may be a problem with the
Internet service provider (ISP) you are trying to connect to, with an external device you
are using to connect to your ISP, or with the server you are trying to access. You can
also try the following steps:
Check the cables and power supplies
Make sure all modem cables are firmly plugged in, including the modem power cord,
the cable from the modem to the computer, and the cable from the modem to the wall
jack. Check the cables and power supplies to Ethernet hubs and routers.
Turn the modem on and off and reset the modem hardware
Turn off your DSL or cable modem for a few minutes, then turn it back on. Some ISPs
recommend that you unplug the modem’s power cord. If your modem has a reset
button, you can press it either before or after you turn the power off and on.
PPPoE Connections
If you are unable to connect to your Internet service provider using PPPoE, first check
the cables and power supplies, then turn the power off and on and reset the modem
hardware.

Appendix C Connecting to the Internet
Check System Preferences settings:
1 Choose Apple () > System Preferences.
2 Click Network.
3 Choose Network Port Configurations from the Show pop-up menu.
4 Drag Built-in Ethernet to the top of the Port Configurations list.
5 Choose Built-in Ethernet from the Show pop-up menu.
6 Click PPPoE.
7 Select “Connect using PPPoE.”
8 Check the Account Name field to be sure you have entered the correct information
from your ISP.
9 Retype your password if you chose to save your password, to be sure it is correct.
10 Click TCP/IP. Make sure you’ve entered the correct information from your ISP
in this pane.
11 Click Apply Now.
Network Connections
If you have two or more computers attempting to share an Internet connection, be
sure that your network is set up properly. You need to know if your ISP provides only
one IP address or if it provides multiple IP addresses, one for each computer.
If only one IP address is used, then you must have a router capable of sharing the
connection, also known as network address translation (NAT) or “IP masquerading.” For
setup information, check the documentation provided with your router or ask the
person who set up your network. The AirPort Extreme Base Station may be used to
share one IP address among multiple computers. For information on using the AirPort
Extreme Base Station, check the onscreen help or visit the Apple AirPort website at
www.apple.com/airport.
If you cannot resolve the issue using these steps, contact your ISP.
