Replacement Instructions

Follow the instructions in this sheet carefully. Failure to follow these instructions could
damage your equipment and void its warranty.
Note: Written and video instructions covering customer-installable parts are available at
http://www.info.apple.com/installparts/.
Warning: During this procedure, keep small parts away from children.

Tools Required
The only tool required for this procedure is a Phillips screwdriver.

Opening the Computer
Warning: Always shut down your computer before opening it to avoid damaging its
internal components or causing injury. After you shut down the computer, the
internal components can be very hot. Let the computer cool down before
continuing.
1. Place your computer on a clean, flat surface.
2. If you think your computer is in sleep, press the power button on the front of the
computer to wake it.
3. Shut down your computer and wait five minutes before continuing.
4. If you attached a security cable through the computer’s lockable cover latch, remove
the cable.
5. Unplug all other cables from the computer except the power cord.

6. Touch the metal PCI access covers on the back of the computer. (Figure 1)
Important: To avoid electrostatic discharge, always ground yourself by touching the
port access covers before you touch any parts or install any components inside the
computer. To avoid static electricity building back up in your body, do not walk
around the room until you have completed your installation and closed the computer.

7. Unplug the power cord.
Warning: The power supply in your computer is a high-voltage component and
should not be opened for any reason, even when the computer is off. If the
power supply needs service, contact your Apple reseller or Apple Authorized
Service Provider.
8. Lift the latch on the right side access panel.
9. Gently lower the access panel until it lies flat. To avoid scratching the case, lower the
panel onto a soft, clean cloth.
Warning: If you see any lights glowing on the main logic board, the computer
has not been shut down. Close the side access panel and shut down the
computer before proceeding.

Removing the Installed Modem

2. Gently pull back the small black latch that holds the modem in place. (This step does
not apply to the Mirrored Drive Doors/FW 800 model.)
3. Lift the modem straight up a short distance to disconnect it from the modem connector
(Figure 2A) on the logic board.
Warning: Use care when disconnecting or connecting the modem. Bent pins in
the modem connector on the logic board could cause a short in the board.

Closing the Computer
1. Raise the side access panel, lift the latch, and press the panel against the case until it
snaps securely into place.
2. Reconnect all cables and restart your computer.
Warning: Never turn on your computer unless all of its internal and external
parts are in place and it is closed. Operating the computer when it is open or
missing parts can damage your computer or cause injury.

Replacing International Modems
After you have replaced a modem in Europe or Asia, open the software utility Modem
Country Selector and verify that the modem is set to the correct country. Modem Country
Selector is located in the Apple Extras folder on your hard drive or can be downloaded as
part of the Apple Modem Updater software bundle at http://www.apple.com/software.
