Apple Macintosh Performa 5400 Series - Manual (Page 120)

Installing an expansion card involves three procedures:
m opening the computer
m inserting the card into a specific slot or socket
m closing the computer
Opening the computer
IMPORTANT To avoid generating static electricity that may damage
components, do not walk around the room until you have completed the
installation of the expansion card or memory 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 on the keyboard.
2 Turn the computer completely off by pressing the power switch at the back of the
computer.
Press the side of the switch marked with the j symbol.
3 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 for now helps protect the computer from
electrostatic discharge damage. (You’ll unplug the power cord later.)
