Setting Up

Congratulations on purchasing your new Power Mac G4 computer. This chapter contains instructions for setting up your computer and display.

Positioning the Computer and Display

You can pick up the computer by any of its handles. If your monitor is heavy, be sure to use correct lifting techniques when positioning it. Position the computer and display so that

m they are on sturdy, ﬂat surfaces m the power cable connectors don’t press against a wall or other object m nothing obstructs air ﬂow in the rear of the display or computer m the computer’s CD or DVD drive tray has space to open in front

Important 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 you can quickly unplug them if necessary.

Plugging In the Computer

1 Set the voltage switch on the back of your computer to the correct voltage, if necessary.

m If your computer doesn’t have a voltage switch, the correct voltage is set automatically

and you can skip this step.

m If your computer has a voltage switch, make sure the voltage switch is set for the voltage

system in your country.

The voltage switch must be set correctly to avoid damaging your computer.

Your computer may have a voltage switch on the back. If you need to change the setting, insert a small screwdriver in this slot and slide the switch.

Set the switch to show “115” for AC voltages in the 100–120V range. Set the switch to show “230” for AC voltages in the 200–240V range.

Using FireWire Devices

Your computer has two FireWire ports. FireWire is a high-speed data transfer system that lets you easily connect and disconnect external devices—such as digital video (DV) cameras, printers, scanners, and hard disks. You can connect and disconnect FireWire devices without restarting your computer.

FireWire ports (2)

These are some of the things you can do with FireWire: m Connect a digital video camera and capture or transfer high-quality video directly to your

computer. Then you can use video-editing software such as Apple’s iMovie to edit the video. Your accessory kit comes with a standard 6-pin to 4-pin FireWire cable that you can use to connect most digital video cameras.

m Connect an external FireWire hard disk drive and use it to back up data or transfer

ﬁles. If you have installed software for your FireWire hard disk, the FireWire disk icon automatically appears on your desktop after you connect the disk drive to your Power Mac G4. Some Fire Wire hard disks get their power through the FireWire cable, so you don’t need to connect an external power supply.

m If you have a problem with your computer that prevents you from starting up or you want

to transfer ﬁles, you can use Fire Wire to connect your Power Mac G4 to another computer so that your Power Mac G4 appears as an external hard disk on the other computer (a feature known as “FireWire target disk mode”).

To use a FireWire device with your computer, connect the device to the computer and install any software that came with the device. Your computer automatically senses when you attach a new device.

To start up from a FireWire hard disk that has the Mac OS on it, use the Startup Disk control panel to select the FireWire hard disk as the startup disk. If your FireWire hard disk doesn’t appear or can’t be selected in the control panel, consult the FireWire hard disk vendor for updated software drivers.

Using AirPort Wireless Networking

AirPort offers an easy and affordable way to provide wireless Internet access anywhere in the home, at work, or in the classroom. Instead of using traditional cables, AirPort uses wireless local area network (LAN) technology to provide wireless communication between multiple computers. Through a wireless network you can set up access to the Internet, transfer ﬁles, play multiplayer games, and more.

Your Power Mac G4 is AirPort-ready. The only thing you need to add is an AirPort Card. See “Installing an AirPort Card” on page 70. You install the AirPort Card in a slot inside the computer and connect it directly to the end of a built-in antenna cable.

How AirPort Provides Wireless Internet Access

With AirPort, you set up a wireless connection to a device known as a base station, which has a physical connection to the Internet. AirPort technology works like a cordless telephone. The handset of the cordless phone makes a wireless connection to the base, which is connected to the telephone line. Similarly, your computer makes a wireless connection to the base station connected to the telephone line or your Ethernet network.

Telephone or Ethernet connection

AirPort Base Station

46 Chapter 3

Wireless Network Connections

If you install an AirPort Card, you can

m connect your computer to a computer network that has wireless access m use your computer to provide network access for other computers using wireless cards m establish a wireless connection and share information with another computer that has an

AirPort Card

Check with your network administrator for more information about reaching the network’s wireless access point.

Warning Several kinds of objects placed near the computer can cause interference. See

the instructions that come with an AirPort Card or AirPort Base Station to learn about avoiding interference. You can also ﬁnd more information in the Apple Technical Information Library: til.info.apple.com

For More Information on AirPort

To purchase an AirPort Card or AirPort Base Station, contact your Apple-authorized dealer or go to the Apple Store at www.apple.com/store

Putting the Computer to Sleep to Save Energy

Power Mac G4 computers are set to go to sleep after a period of inactivity. Sleep is a state in which your computer uses very little power. You can also put the computer to sleep whenever you want.

Note: Macintosh Server G4 computers are not set to sleep, but you can set them to do so. When the computer goes to sleep, it saves its state so that when you wake the computer,

your programs, documents, and control panel settings are exactly as you left them. You use the Energy Saver control panel, part of the computer’s system software, to adjust sleep settings. For further energy savings, shut down the computer and disconnect it from its power source or turn off the power strip when the computer is not in use.

Using Your Computer 47

To put your computer to sleep, you can

m press the power button on the front of the computer m select a sleep mode in the Energy Settings portion of the Control Strip m choose Sleep from the Special menu

When the computer is in sleep, the front panel power button light pulses. You wake the computer by pressing the power button on the front panel of the computer or

by pressing a key on the keyboard. With some Apple monitors, you can also use the monitor power button to put the computer to sleep and wake it.

Not all PCI cards or replacement AGP cards comply with the computer’s power management standards. If you install a non-compliant card, the computer can still enter sleep mode, but it will not achieve maximum energy savings. You can use the Apple System Proﬁler to ﬁnd out whether an installed card is compliant.

For more information about energy-saving options, see Mac Help.

Attaching SCSI Devices to Your Computer

Some Power Mac G4 computer conﬁgurations come with an Ultra160 Dual Channel SCSI card installed in a PCI slot with one or more internal SCSI hard disks connected to it. You can install additional internal SCSI hard disk drives up to a maximum of three drives. It’s recommended that you only connect SCSI Ultra160 LVD hard disk drives to the internal port of the Dual Channel SCSI card. You can connect external SCSI devices, including older drives with slower data transfer rates, to the external port of the Ultra160 Dual Channel SCSI card. Because the card has two channels, one connected to the internal port and another connected to the external port, connecting older devices to the external port doesn’t slow down the transfer rate of the internal hard disk drives.

Apple recommends that you use only SCSI Ultra160 LVD devices as internal hard disk drives. To connect older SCSI devices that use a 25-pin or a 50-pin connector—such as Zip drives,

scanners, or DAT drives—you need to purchase SCSI adapters, or purchase and install an additional“legacy” SCSI PCI card (one that supports older devices).

For more information about using different types of SCSI devices with your computer, see the Tech Info Library at Apple’s Web site: til.info.apple.com

48 Chapter 3

Transferring Information Between Two Macintosh Computers

If two Macintosh computers are not connected by a network, you can transfer information between them by connecting them with an Ethernet crossover cable (in effect creating a small network of just two computers), which you can buy from an Apple-authorized dealer. You connect the cable to each computer’s Ethernet port and then turn on file sharing on both computers, or conﬁgure the computers’ Ethernet settings to create a small network. For more information about conﬁguring such an Ethernet connection, see Mac Help.

You can also connect two Macintosh computers using a FireWire cable. You can then use FireWire target disk mode to transfer ﬁles from one computer to another. For more information about using FireWire target disk mode, see “FireWire Target Disk Mode” on page 41.

If you have an Internet connection, you can also transfer ﬁles via the Internet to your iDisk storage area on iTools, where you or another iTools user can download them. For more information about iTools, see “iTools—Free Internet Services for Mac Users” on page 22.

Using the Computer as a Server Without a Monitor

You can set up your computer to run as a server without an attached monitor. Follow these steps:

1 Follow all the steps described in Chapter 1 to set up your computer, including connecting a

monitor, mouse, and keyboard.

2 Conﬁgure your server software as follows:

m Conﬁgure network access. m Conﬁgure the Apple Network Assistant Security application so the server can be controlled. m Set passwords for access to the server. m Set AppleShare IP services to start up when the system starts up. m Set the computer not to go to sleep. Macintosh Server G4 computers are shipped

this way.

3 Be sure network services are operating properly. 4 Turn off the server and disconnect the monitor. 5 Turn on the server.

When you turn on your server, the AppleShare IP services launch automatically after the system starts up.

If you’re using remote access software, follow the instructions that came with your software for logging in to and controlling the server.

Installing Ultra160 LVD SCSI Drives

If your Macintosh has an internal Ultra160 LVD SCSI drive, you can connect up to two more internal Ultra160 LVD SCSI drives to the PCI card and cable inside the computer. This cable has the required connectors and a built-in terminator, so you don’t need to add one.

If you have one Ultra160 LVD SCSI drive, it is installed in lower drive position 1. The computer uses the drive in position 1 to start up.

Note: If your computer doesn’t have a SCSI hard disk drive, you need to install a SCSI PCI card in your computer to connect SCSI hard disks.

The procedures for disconnecting and connecting a SCSI hard disk drive and for removing and inserting drive carriers are nearly identical to those presented in the ATA drive installation instructions on page 57. Follow the ATA drive instructions when installing a SCSI drive. However, before installing your SCSI drive, note the following differences:

When you configure your SCSI hard disk drive

Assign a unique SCSI ID number to each new device. A single factory-installed drive uses SCSI ID 0; a second factory-installed drive uses SCSI ID 1; and a third factory-installed drive uses SCSI ID 2. The SCSI PCI card has been assigned ID 7. If you select one of these numbers for a new drive, the drive will not work properly.

When you attach the drive to the carrier

If you’re installing a SCSI drive in a computer that came with one SCSI drive, install the new drive in position 3 (see “Inside Your Power Mac—Your Computer’s Internal Expansion Options” on page 18). Do not install a SCSI drive in the top position of the U-shaped bracket.

64 Chapter 4

SCSI drives that are 1" high are attached to the lower portion of the drive carrier from the bottom.

Position the hard disk drive on the drive carrier so that the ribbon cable connector and the power cord connector are accessible.

SCSI drives that are 1.6" high are attached to the lower portion of the drive carrier by screwing it into position on its sides.

Note: The tinted screws in the previous illustration indicate the four low-proﬁle screws that came with the computer. The untinted screws in the following illustration show the screws that come with the new drive.

Attach additional SCSI drives (1" or 1.6" high) to the two flat drive carriers by screwing them into position from the bottom.

Position the hard disk drive on the drive carrier so that the ribbon cable connector and the power cord connector are accessible. Screw the drive into position with the four screws supplied with the drive.

When you replace the carrier and reconnect the drive cables

If your computer came with a SCSI hard disk drive installed in drive position 1, and you are installing a SCSI hard disk drive in drive position 2 or 3, put the ribbon cable on top of the drives. You can tape the ribbon cable to the tops of the drives with double-stick foam tape to make the cable lie flat.

SCSI terminator

PCI SCSI card The ribbon cable may attach to a different position on the PCI SCSI card, depending on the card you have.

Make sure all of the power cord and ribbon cable connectors are firmly attached to all of the drives and to the PCI SCSI card.

Working Inside Your Computer 65

Installing a PCI Expansion Card or Replacing the AGP Card

You can expand the capabilities of your Power Mac G4 by installing cards in its expansion slots. The computer has ﬁve expansion card slots, four of which accommodate peripheral component interconnect (PCI) cards and one that accepts an AGP card.

AGP cards and PCI cards have different connectors, so you cannot insert a PCI card into the AGP slot.

About AGP Cards

Your AGP card, installed in slot 1, provides the computer’s monitor port. Slot 1 is designed speciﬁcally to accept AGP cards that have a 32-bit data width. This 66 megahertz (MHz) slot accommodates 3.3 volt (V) AGP cards (see the image on page 68).

You can replace the card that came with the computer with an AGP 1X card, 2X card, or 4X card. A replacement AGP card must have a driver compatible with the Mac OS. Maximum power consumption for a replacement AGP card should not exceed 20 watts (W).

About PCI Expansion Cards

Your Macintosh has four expansion slots, labeled 2, 3, 4, and 5, which accept PCI cards up to 12 inches long. Some models come with a SCSI PCI card installed in one of these slots. Install only expansion cards that come with Macintosh driver software and that comply with the PCI 2.1 standard.

The PCI slots can accommodate mixed voltage (5.0 V or 3.3 V) cards with 32-bit or 64-bit data widths and a 33 MHz frequency. You can add a 66 MHz card to a PCI slot if the card can operate at the lower 33 MHz rate.

66 Chapter 4

Warning Do not use cards that function only at 66 MHz in the PCI slots. Damage to your

equipment could result. If you have a 66 MHz card, check the card’s manufacturer to see if it also works at 33 MHz.

Maximum power consumption for all ﬁve expansion slots (the four PCI expansion cards and the AGP card) should not exceed 55 watts (W).

Installing Your Card

Install an AGP card in slot 1 only. Install PCI expansion cards in the slots labeled PCI 2, 3, 4, and 5.

1 Remove the screw that holds the port access cover in place, pull out the access cover, and set

APPENDIX

B Safety , Maintenance, and Ergonomics

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. Similarly, to disconnect your display completely, you must also unplug its power cable from the computer or other power outlet. Make sure 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 from your computer or display if any of the following

conditions exists:

m the power cord or plug becomes frayed or otherwise damaged m you spill something into the case m your computer or display are exposed to rain or any other excess moisture m your computer or display have been dropped or the case has been otherwise damaged m you suspect that your computer or display needs service or repair m you want to clean the computer or display case or screen

To prevent accidents and damage to your computer or display, be sure that you always follow these instructions:

m Keep your computer and display away from sources of liquids and moisture. m Don’t set anything on top of the computer or display. m Keep the computer and display vents free from obstruction. m Never remove the case from the monitor, or open your computer when it’s running. You

could come in contact with hazardous voltage.

m During lightning storms, disconnect your modem from the phone jack to prevent a

destructive voltage overload from damaging the modem.

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 monitor. Be sure to use correct lifting procedures, lifting with your legs. When carrying the monitor, make sure the monitor is facing you. Don’t carry the monitor 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 electrical cables.

84 Appendix B

General Maintenance

If you need to clean the computer or display beyond wiping them down with a clean cloth, follow these instructions:

1 Turn your computer and display off. 2 Disconnect the computer power cable from the electrical outlet or power strip. If your

display has a power cable 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.

5 Wipe the computer or display case surfaces lightly with a clean, soft cloth dampened with water.

Don’t use alcohol, aerosol sprays, solvents, or abrasives that might damage the ﬁnish on the case.

Protecting Your CD or DVD Drive

To keep your CD or DVD drive working properly:

m Position your computer so that the drive tray doesn’t bump into anything when it opens. m Close the drive when you’re not using it. m Do not put anything on the drive tray when it is open. m Do not touch the 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.

m Keep your computer away from any source of moisture.

Safety, Maintenance, and Ergonomics 85

Maintaining Your Display

To maintain your display and ensure its long life:

m Do not press on the surface of the display screen. m Do not write on the screen or touch the screen with a sharp object. m 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.

m Turn off your monitor, 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.

m 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.

m 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 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 may 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.

m Position the mouse at the same height as your keyboard. Allow adequate space to use the

mouse comfortably.

m Arrange the monitor so 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).

86 Appendix B

m Position the monitor to minimize glare and reﬂections on the screen from overhead lights

and nearby windows. If possible, use a tiltable monitor stand. The stand lets you set the monitor 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.)
