Installing the Card

in a Power Macintosh 4400 or 7220

This chapter describes how to install the PC Serial and Parallel Card in a Power Macintosh 4400 or a Power Macintosh 7220.

After you install the PC Serial and Parallel Card hardware, go to Chapter 6, “Updating Your PC Compatibility Card Software.” Then turn to Chapter 7 to learn more about connecting PC-compatible equipment to your PC Serial and Parallel Card.

What you need

Before beginning the installation process, make sure you have the necessary parts: the PC Serial and Parallel Card and the peripheral flex cable. You’ll also need a Phillips screwdriver and your PC Compatibility Card user’s manual.

Installing the PC Serial and Parallel Card hardware

WARNING

The installation of the PC Serial and Parallel Card is technically complex. Unless you are comfortable installing components inside computers, Apple recommends that you have the PC Serial and Parallel Card installed by your Apple-authorized dealer (who may charge a fee). If you attempt to install the card yourself, any damage you may cause to your equipment will not be covered by the limited warranty on your computer.

Do not attempt to install the card or connect the cables without first reading this manual.

There are several steps to installing your PC Serial and Parallel Card hardware:

m opening the computer m preparing the slots m attaching the peripheral flex cable to the PC Compatibility Card m attaching the peripheral flex cable to the PC Serial and Parallel Card m inserting the PC Serial and Parallel Card m replacing the computer cover

Chapter 1

Opening the computer

Firmly grasp the back of the computer and push in on the rear panel with your fingertips while sliding the top cover back about a quarter of an inch with your thumbs.

Remove these three screws.

1Shut down the computer and disconnect all cables from the computer, except for the

power cord.

Leave the computer plugged in for now, to ground it and protect its components from static electricity damage.

2 Remove the three screws as shown from the back of the cover.

3Position your hands on the unit as shown and slide the cover back.

5 Touch the metal part of the power supply case inside the computer.

Always do this before you touch any parts, or install any components, inside the computer. Touching the power supply case helps release static electricity from your body and prevent possible damage to internal components.

IMPORTANT

You can collect static electricity just by walking away from and then back to your computer. If you need to move away from your computer during installation, remember to touch the metal part of the power supply case again before you continue installing.

6Disconnect the power cord from the back of the computer.
