Telephone Line Problems
If your telephone doesn’t work, there may be a problem with your telephone line. Disconnect the modem to see
if the problem goes away. If it doesn’t, report the problem either to your local telephone company or to your
company’s telecommunications people.
If disconnecting the modem eliminates the problem, the modem itself may need service. See the service and
support information that came with your Apple product for instructions on how to contact Apple or an Appleauthorized service provider for assistance.
If you do not disconnect your modem when it is adversely affecting the telephone line, the telephone company
has the right to disconnect your service temporarily until you correct the problem. The telephone company will
notify you as soon as possible. Also, you will be informed of your right to file a complaint with the FCC.
The telephone company may make changes in its facilities, equipment, operations, or procedures that could
affect the operation of your equipment. If this happens, the telephone company will provide advance notice in
order for you to make the necessary modifications to maintain uninterrupted service.
The internal modem will not work with party lines, cannot be connected to a coin-operated telephone, and may
not work with a private branch exchange (PBX).
Telephone Consumer Protection Act
The Telephone Consumer Protection Act of 1991 makes it unlawful for any person to use a computer or other
electronic device to send any message via a telephone fax machine unless such message clearly contains in a
margin at the top or bottom of each transmitted page or on the first page of the transmission, the date and time it
was sent and an identification of the business or other entity, or individual sending the message and the
telephone number of the sending machine of such business, entity, or individual.

Note: Make sure to connect the phone cord connector (RJ-11) to the modem port and not
to the Ethernet port, which accepts a similar connector (RJ-45) that is slightly larger.
To connect an external USB modem: Use a USB cable to connect the modem to a free USB
port on the keyboard, computer, USB monitor, or USB hub.
26
Chapter 1
Check the documentation accompanying the modem to see if it needs to be plugged into a
power outlet. Also look for instructions about installing modem software and connecting the
modem to a telephone line.
Warning Disconnect your modem from the phone jack during lightning or thunder
storms. This will prevent a destructive voltage overload from damaging the modem.
More information about the optional internal modem is available in the electronic
documentation that came with your computer.
Connecting to an Ethernet Network
The computer comes with a built-in 10/100 twisted-pair Ethernet port, which extends your
computer’s features by giving you access to the services and resources provided on a 10
megabit (Mbit) or 100 Mbit Ethernet network. Your computer alone lets you store, retrieve,
and modify information on hard disks, removable media disks, and CD-ROM or DVD-ROM
discs. On a network, you can also store and retrieve information on other computers, access
information that other people have stored for you, use electronic mail, share resources such
as printers and modems, and access the Internet, if the network has a link to it. (Access to
the Internet over a network may be noticeably faster than access with a modem.)
If you’re connecting to an existing network, you may be able to get information about the
network and the software you need to use it from the specialist—referred to as the “network
administrator”—who oversees its operation. Identify your organization’s network
administrator before you begin.
Note: When connecting to a 100Base-TX network, use category 5 twisted-pair cable. When
connecting with a 10Base-T network, you can use category 3 or category 5 twisted-pair cable.
For more information about using your computer on a network or setting up a network, see
the electronic documentation that came with your computer.
Connecting to a 10/100 twisted-pair Ethernet network
You can connect directly to a 10/100 twisted-pair Ethernet network before or after you start
up the computer.
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 repeater from a manufacturer other than Apple.
See your Apple-authorized dealer for more information on Apple Ethernet media adapters.
Setting Up
27
To connect your Macintosh to a centralized 10/100 twisted-pair network, follow these steps:

support information that came with your computer for instructions on how to contact an
Apple-authorized service provider or Apple for service. If you install these items yourself,
you risk damaging your equipment, and such damage is not covered by the limited
warranty on your computer. See an Apple-authorized dealer or service provider for
additional information about this or any other warranty question.
33
About Memory
Your computer can accommodate additional dynamic random-access memory (DRAM) in
packages called Dual Inline Memory Modules (DIMMs). The following illustration shows the
memory slots on the logic board. See the sections that follow for important information
about DRAM.
PCI slots 2-4: 33 MHz PCI slots (3)
PCI slot 1: 66 MHz PCI slot
(graphics card installed)
Battery
SDRAM slots (4)
Video memory ( VRAM) for standard Macintosh models is supplied by synchronous DRAM
(SDRAM) soldered onto the 66 MHz graphics card that supplies the computer’s monitor
port. Standard Macintosh models come with a minimum of 16 megabytes (MB) of SDRAM
video memory.
If your computer has the Mac OS installed, you can use the Apple System Profiler to check
the amount of DRAM and VRAM installed in your computer.
34
Chapter 2
DRAM Configurations
Your computer’s DRAM can be expanded to a maximum of 1024 MB by adding DIMMs to the
four DRAM DIMM slots on the main logic board.
DIMMs must fit these specifications:
m “PC-100” Synchronous DRAM (SDRAM)
m 3.3 volt ( V )
m 64-bit wide, 168-pin module
m Maximum number of memory devices on DIMM is 16
m Unbuffered; do not use registered or buffered Synchronous DRAM (SDRAM)
m Height must not exceed 2.0 inches
This computer uses SDRAM DIMMs. DIMMs from older Macintosh computers
are not compatible with your computer and should not be used even though they fit into the
DRAM DIMM slots.
Important
Note: Different size DRAM DIMMs can be installed in any order in any DIMM slot. Unlike
older Macintosh computers, DIMMs need not be installed in pairs.
To increase DRAM to the maximum of 1024 MB, fill all four slots with 256 MB DIMMs. Any
256 MB DIMMs you install must use 128 megabit (Mbit) device technology.
For instructions on installing DRAM, see the section “Installing DRAM” on page 44.

About Internal Storage Options
Your Macintosh has five internal drive bays. Three are in the lower part of the computer and
two are in front on top. In many configurations, a single hard disk occupies the rear position
on the lower drive carrier, and a CD-ROM or DVD-ROM drive and Zip drive fill the upper
bays.
The computer supports additional SCSI drives, which fit on the lower drive carrier.
Depending on the configuration you purchased, one or two additional SCSI drives can go in
the unoccupied positions on the carrier. (Some drives also require a PCI card to function.)
For technical information about the power requirements for devices the computer can
accommodate, see the electronic documentation that came with the computer.
CD-ROM/DVD-ROM drive bay

These are the dimensions of drives that can be installed:
m Width: 102 mm (3.9 inches)
m Height: 25.4 mm (1.0 inch)
m Depth: 147 mm (5.7 inches)
The computer provides support for the following types of internal hard disk drives:
m ATA devices (includes ATA, ATA-2, and ATA-3 devices, which are also called IDE or EIDE
devices)
m Ultra ATA devices (sometimes called ATA-4 devices)
m Wide Ultra SCSI devices (with the PCI card included in some configurations)
m Wide Ultra2 SCSI devices (with the PCI card included in some configurations)
m ATAPI drives, including CD-ROM, DVD-ROM, and Zip drives
For more information about devices supported, see your Apple-authorized dealer and the
support section of Apple’s Web site: http://www.apple.com/support/
Hard disk drives and removable storage devices may require special software for
the computer to recognize the device. Check the documentation that came with your device
or contact the device’s manufacturer for more information.
Important
Drives Installed in the Computer and Additional Drives
Standard Macintosh configurations include one internal Ultra ATA hard disk, or one, two, or
three internal Wide Ultra2 SCSI drives. The drives you purchased with your computer can
influence what additional drives you select.
Ultra ATA Drives
Your Macintosh can accommodate one internal ATA device in the lower drive carrier. If you
purchased a model with an Ultra ATA drive in it, the drive sits in the rear of the carrier in
position number 3.
Additional Wide Ultra2 SCSI Drives
If you purchased a Macintosh model that has at least one internal Wide Ultra2 SCSI drive, a
PCI card and cable inside the computer make it possible to connect additional internal and
external Wide Ultra2 SCSI devices. You can connect up to three internal SCSI drives or
connect additional SCSI devices to the port the card provides on the rear of the computer.
If your computer came with one Wide Ultra2 SCSI drive, it is installed in the lower drive in
position 1, near the front of the computer. If it came with two drives, the second one is
installed in position 2. If a third drive is installed, it’s in position 3. The computer uses the
drive in position 1 to start up.
Working Inside the Computer
37
Additional internal Wide Ultra2 SCSI devices connect to the data cable supporting the drive
that came with the computer. This cable has a built-in terminator so you don’t need to add
one.
You must assign a SCSI ID number to every additional device and the number must not
conflict with the ID number already assigned to a drive on the SCSI chain. If your computer
came with one Wide Ultra2 SCSI drive, it has ID 0. If the Macintosh came with two drives,
they have ID 0 and 1. A third factory-installed drive has ID 2. The SCSI PCI card has ID 7.
Other Types of SCSI Drives
The SCSI card inside your Macintosh supports other types of Wide Ultra SCSI drives, as well
as Wide Ultra2 SCSI devices. However, if you mix the different kinds, your system will operate
at the speed of the slowest device. If you want optimal performance using the card, use only
Wide Ultra2 SCSI devices. To maintain optimal performance using another kind of SCSI
device, add a PCI card that supports the device.
Instructions for drive installation appear in the section “Installing a Hard Disk or Other
Internal Storage Device” on page 46.
About PCI Expansion Cards
Your Macintosh can accommodate additional printed circuit boards (cards) for video and
graphics applications, networking and communications, additional processing power, or
other purposes. The cards fit into connectors, called expansion slots, inside the computer.
Your Macintosh has four expansion slots, each of which accepts a PCI card up to 12 inches
long. Install only expansion cards that come with Macintosh driver software and that comply
with the PCI 2.1 standard. NuBus™ cards cannot be used in these expansion slots.
In standard Macintosh models, a graphics card that supplies a monitor port occupies the PCI
slot labeled number 1. This slot can accommodate 3.3 volt ( V ) cards with 66 MHz frequency
and 32-bit data widths only.
The other three PCI slots can accommodate mixed voltage (5.0 V or 3.3 V ) cards with a
33 MHz frequency and 32-bit or 64-bit data widths. These slots will not accommodate 66 MHz
cards.
38
Chapter 2
Expansion Card Power Requirements
The combined power consumption of expansion cards must not exceed the limits specified
for your Macintosh model. For details, see the technical information section in the electronic
documentation that comes with your computer.
You can use the three 33 MHz expansion slots to install
m three 15 W cards
m one 15 W or 25 W card
m two 15 W or 25 W cards
m one 15 W card and one 25 W card
To avoid damaging your computer and expansion card, do not attempt to
install any expansion card without first checking the documentation for that card. If the
documentation specifies that an Apple-certified technician must install the card (usually
because the installation requires special training or tools), consult the service and support
information that came with your computer for instructions on how to contact an Appleauthorized service provider for assistance. If you attempt to install the card yourself, any
damage you may cause to the computer or card will not be covered by the limited
warranty on your computer. If the card is not an Apple-labeled product, check with an
Apple-authorized dealer or service provider to see if you can install it yourself.
Warning
For instructions on installing PCI cards, see the section “Installing a PCI Expansion Card” on
page 57.
About the Computer’s Battery
The Macintosh has a 3.6 V lithium backup battery installed on the main logic board. Some
signs that you need to replace the battery are intermittent problems starting up your
computer and the date randomly resetting. Replacement batteries for the Macintosh are
available in many electronics and computer stores. You can install the new battery yourself or
have an Apple-authorized dealer do it for you for a fee.
Replacing the battery may cause some settings on your computer, such as the date and
network settings, to revert to factory default settings. You may also have to restore modem
settings in any communications programs you are using.
Important
Make a note of the settings for communications programs before you replace
the battery.

cable to the top of the drive with double-stick foam tape to make it lie flat.
To use a type of SCSI device other than Wide Ultra2, it’s best to add a PCI card that supports
the device. The factory-installed Wide Ultra2 SCSI card supports some other types of SCSI
devices, but not optimally. For information on PCI card installation, go to the section
“Installing a PCI Expansion Card” on page 57 and then return to step 7 in this section.

Set the drive carrier back inside the computer and slide it toward the front of the computer
until it locks in its original position.
Make sure the carrier engages the guides and is securely seated in the computer.
Warning When replacing the drive carrier inside the computer, don’t crimp or abrade
the data cables that connect to the main logic board.
Gently place the entire drive carrier
assembly back into the computer and
slide it toward the front of the computer
until it is firmly seated. Be careful not
to crimp or abrade any wires that are
near or under the assembly.

m If you added a SCSI drive to a computer that came with an ATA drive, attach the main
power cable bundle and the ATA ribbon cable to the main logic board and the SCSI ribbon
cable to the SCSI PCI card.
m If you added a SCSI drive to a computer that came with one or two SCSI drives, attach
the main power cable bundle to the main logic board and the SCSI ribbon cable to the
PCI card.
If you have a third-party SCSI PCI card, see the instructions that came with it for information
on connecting the ribbon cable.
Plug the power cord bundle back
into the main logic board.
This ribbon cable
connector attaches to a
PCI SCSI card. If you bought a
third-party SCSI card, follow the
directions that came with it to find
out how to attach the ribbon cable correctly.

1
Remove the screw that holds the port access cover in place, pull out the access cover, and set
it aside.
If you want to replace or remove a card that’s installed in the computer, remove the screw
that holds the card in place and pull the card from the slot.

Align the card’s connector with the expansion slot and press down until the connector is
inserted all the way into the slot.
If you’re installing a 12-inch card, make sure the card engages the appropriate guide at the
front of the computer.
Reinstall the screw to
secure the card in place.

Press the card gently but firmly until the connector is fully inserted.
m Don’t rock the card side to side; instead, press the card straight into the slot. (Rocking the
card can damage the PCI slot.)
m Don’t force the card. If you meet a lot of resistance, pull the card out. Check the
connector and the slot for damage or obstructions, then try inserting the card again.
m 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. (Make sure you don’t pull the
card so much that you accidentally disconnect it.)
4
Reinsert the screw that you removed earlier and tighten it to hold the PCI card in place. If
you have other cards to install, put them in now by repeating steps 1–3.
If you removed a card from your computer and did not install a replacement, install a port
access cover plate next to the slot using the screw that held the card in place. The access
cover maintains the correct air flow and keeps the computer’s components from
overheating.
Warning Do not leave an empty PCI slot uncovered. An uncovered port can affect the
air flow that cools the computer’s internal components and cause damage.

What’s Next?
Before you can start using the equipment you installed, you may need to install software that
the equipment requires or configure the equipment. For example, PCI expansion cards
usually require special software, and hard disks may need to be initialized with a diskformatting utility. See the documentation that came with the equipment for additional
installation or configuration instructions.
Some older devices may require updated drivers to work with your computer. (A driver is
special software that is installed in your System Folder.) Contact the device’s manufacturer
for information on obtaining driver software.
Additional information about how to use your computer is available in the electronic
documentation included with your computer’s system software.
