Installing an expansion card
The Macintosh comes with a slot inside called a processor-direct slot in which you can install a processor-direct expansion card for special purposes. Some expansion cards are designed so that you can install them yourself. Others can be installed only by an Apple- authorized representative. To install a card, use the documentation supplied with the card you plan to install, or follow the instructions in this section.
sWarning: If you have installed a floating-point unit (FPU) on the main logic board of your Macintosh, do not install an expansion card that also contains one. If you have two FPUs, your Macintosh may not work properly. s
sWarning: 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 Apple-authorized service provider or Apple 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. s
To install an expansion card:
1.Choose Shut Down from the Special menu or press the Power key on the keyboard.
2.Turn off the computer completely by pressing the main power switch at the back of the computer.
3.Unplug the cable that connects your keyboard to the computer.
4.If there are screws on either side of the back panel, remove them.
