Your Mac Pro 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 get started.
Step 1: Position your Mac Pro and display
Pick up your Mac Pro by both of its handles using correct lifting techniques. If your
display is heavy, use correct lifting techniques when positioning it as well. Position your
Mac Pro and display so that:
Â
They are each on a sturdy, flat surface
Â
The power cable connectors don’t press against a wall or other object
Â
The airflow in front of, behind, and below your Mac Pro and the display is not
obstructed
Â
The computer’s optical drive trays have space to open in front
The only way to shut off power completely to your Mac Pro and display is to
disconnect their power plugs from the power source. Make sure the power cords for
your Mac Pro and display are within easy reach so that you can unplug them.

Installing Memory
Your Mac Pro has two memory cards with four memory slots on each card (in four
banks of two each). Your Mac Pro comes with a minimum of 2 GB of memory, installed
as a pair of 1 GB fully buffered dual inline memory modules (FB-DIMMs) in two of the
DIMM slots. You can install additional pairs of 1 GB, 2 GB, or 4 GB FB-DIMMs in the open
DIMM slots on the memory cards, for a total of 32 GB of memory.
DIMMs must be installed in matched pairs and fit these specifications:
 800 MHz, DDR2, FB-DIMMs
 72-bit wide, 240-pin modules
 36 memory ICs maximum per DIMM
 Error-correcting code (ECC)
Important: Apple recommends that you use Apple-approved FB-DIMMs. Other
FB-DIMMs may cause your Mac Pro to operate louder or decrease performance to
conserve heat. DIMMs from older Mac computers cannot be used in your Mac Pro.
Note: When purchasing DIMMs for use in Mac computers, make sure that the memory
vendor conforms to the Joint Electron Device Engineering Council (JEDEC)
specification. Check with your memory vendor to ensure that the DIMMs support the
correct timing modes and that the Serial Presence Detect (SPD) feature has been
programmed properly, as described in the JEDEC specification. To check the
compatibility of your DIMMs, see the Macintosh Products Guide on Apple’s website at
www.apple.com/guide. You can purchase Apple-branded memory online from the
Apple Store at www.apple.com/store.

Maximizing Ethernet Performance
Your computer performs best when the Ethernet port to which it is connected is set to
autonegotiate. 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 autonegotiate, if possible. If a switch’s port is not
autonegotiating, your computer detects the appropriate speed but defaults to halfduplex mode. If the switch’s port at the other end of the link is configured for fullduplex mode, a large number of late events can occur on the link. If it isn’t possible to
set the switch to autonegotiate, then set the switch’s port to half-duplex. For more
information, see the documentation that came with the Ethernet switch.
Note: If you connect your computer directly to a configurable Ethernet switch, have
your network administrator disable the spanning tree protocol on that port. Otherwise
your computer may duplicate the AppleTalk address of another computer on the same
network and both network connections may become unreliable.

This chapter provides important information about safety procedures, routine
maintenance, and ergonomic considerations for using your Mac Pro and display.
For your safety and that of your equipment, follow these rules for handling and
cleaning your Mac Pro and for working more comfortably. Keep these instructions
handy for reference by you and others.
Important Safety Information
WARNING: Failure to follow these safety instructions could result in fire, electric
shock, or other injury or damage.
The only way to disconnect power completely from your Mac Pro 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.
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
96 Chapter 6 Last, but Not Least
 You suspect that your computer or display needs service or repair
 You want to clean the computer or the case or screen of the display
 If you plan to store your computer for an extended period of time, remove the
battery.
For service or questions about your warranty, contact an Apple Authorized Service
Provider or Apple. Service and support information is included with your computer’s
documentation.
General Maintenance
If you need to clean the computer or display by doing more than wiping it down with
a clean cloth, follow these instructions:
1 Turn off your computer and display.
2 Disconnect the computer power cable from the electrical outlet or power strip. If your
display is connected to an outlet, disconnect it as well.
3 Disconnect the display’s cables from the computer.
4 Clean the display screen with soft, lint-free paper or cloth dampened with mild soap
and water.
WARNING: Do not spray liquid directly onto the display screen. Liquid could drip
·
inside the display and cause electrical shock.
Chapter 6 Last, but Not Least 97
5 Wipe the computer or display case surfaces lightly with a clean, soft cloth dampened
with water.
NOTICE: Don’t use alcohol, aerosol sprays, solvents, or abrasives that might damage
the finish on the case.
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.
Laser Information for Optical Disc Drive
WARNING: Making adjustments or performing procedures other than those specified
·
in your equipment’s manual may result in hazardous radiation exposure.
The optical disc drive in your computer contains a laser that is safe in normal use but
that may be harmful to your eyes if disassembled. For your safety, have this equipment
serviced only by an Apple Authorized Service Provider.

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 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.
Cleaning Your Mighty Mouse
You may need to clean your mouse from time to time to remove dirt and dust that has
accumulated in the scroll ball area. Hold the mouse upside-down and roll the scroll ball
vigorously using a clean, soft, lint-free cloth to help dislodge any particles that may
interfere with proper scrolling.
Chapter 6 Last, but Not Least 99
Understanding Ergonomics
Here are some tips for setting up a healthy work environment.
 Use an adjustable chair that provides firm, comfortable support. 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 the 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 the keyboard and within comfortable
reach.
 Arrange the display so that the top of the screen is slightly below 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).
