Apple Power Macintosh 4400 - Manual (Page 37)

The illustrations on the next pages show the basic computer system you now
have. So that you can expand your system’s capabilities, your computer has
external ports to which you can connect additional hardware, such as a printer
or scanner.
Your computer also has internal slots for adding items to increase its
capabilities and performance. Among these items are additional dynamic
random-access memory Dual Inline Memory Modules (DIMMs); a High
Performance Module (256K level 2 cache); and expansion cards, such as PCI
(peripheral component interconnect) and Ethernet cards. Instructions for
installing these internal items are provided in Chapter 10, “Installing
Expansion Cards and Additional Memory.”
WARNING Before you connect any equipment to your computer, make
sure that your computer is plugged in (in order to ground the
computer) and turned off. If you connect equipment with the
computer turned on, you can damage your computer and your
equipment. Also, each device you add should be compatible with your
computer and must not exceed the maximum power allowance for that
device. For more information consult an Apple-authorized dealer, the
manufacturer of the equipment you add, or the Technical Information
booklet that came with your computer.
