Setting Up Your Computer
Positioning and plugging in the computer
Place your equipment on a sturdy, flat surface near a grounded wall outlet.
(Your computer was designed to be placed on the floor to conserve desk
space, but it can also be placed on any stable, flat surface.)
Before you plug your Macintosh into a wall socket, carefully read all the
setup instructions in this chapter. Then, before you connect any other
equipment to your Macintosh, follow the instructions in this section to plug it
in. The plug grounds the computer and protects it from electrical damage
while you set up. When you are ready to begin, follow these steps:
1Plug the socket end of the computer’s power cord into the recessed power socket
(marked with the symbol
≤
) on the back of the computer.
2Plug the other end of the power cord into a three-hole grounded outlet or power strip.

WARNING
This equipment is intended to be electrically grounded. Your
Macintosh is equipped with a three-wire grounding plug—a plug that
has a third (grounding) pin. This plug will fit only a grounded AC outlet.
This is a safety feature. If you are unable to insert the plug into the
outlet, contact a licensed electrician to replace the outlet with a properly
grounded outlet. Do not defeat the purpose of the grounding plug!
