Apple Macintosh Performa 6400 Series - Manual (Page 129)

Installing an expansion card involves three procedures:
m opening the computer
m inserting the PCI or communication card into a specific slot
m closing the computer
Opening the computer
IMPORTANT To avoid generating static electricity (from your body) that may
damage components, do not walk around the room until you have completed
the installation of the expansion card and closed the computer. Additionally,
move the logic board as little as possible while it is outside the computer case.
1 Shut down your computer by choosing Shut Down from the Special menu.
You can also press the Power key (marked with a π) on the keyboard.
2 Unplug all the cables except the power cord from the computer (including the cable that
connects your keyboard to the computer).
Leaving the power cord plugged in helps protect the computer from
electrostatic discharge damage. (You’ll unplug the power cord later.)
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-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 your computer or card will not be covered by the limited
warranty on your computer. If the card is not an Apple-labeled product,
contact Apple directly to see if you can install the card yourself. See the
service and support information that came with your computer for a
telephone number to contact Apple.
