Installing an expansion card

The Macintosh LC 520 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 authorized Apple representative. To install a card, use the

documentation supplied with the card you plan to install, or

follow the instructions in this section.

s Warning: If you have installed a floating-point unit (FPU) on

the main logic board of your Macintosh LC 520, do not install

an expansion card that also contains one. If you have two

FPUs, your Macintosh LC 520 may not work properly.

s Warning: 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-authorized dealer

or service provider must install the card (usually because

the installation requires special training or tools), be sure to

have your Apple dealer or service provider do the installation.

If you attempt to install the card yourself, any damage you

cause to your computer will not be covered by the limited

warranty on your computer. If the card is not an Apple-labeled

product, then check with an authorized Apple dealer or

service provider to see if you can install it yourself.

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.
