Installing a PCI expansion card or memory
Follow these instructions to install a PCI expansion card or memory.
Opening the computer
1 If your computer is turned on, turn it off by choosing Shut Down from the Special menu,
then wait 20 minutes.
Before proceeding with these instructions, you need to allow the computer’s
internal components to cool.
2 Make sure the voltage switch is set correctly for the voltage system to which you will be
connecting the computer.
If you don’t know the voltage used in the country you’re in, refer to the table,
“Voltages for Different Locations,” in the section “Plugging In the Computer”
in Chapter 1, “Setting Up Your Computer.”
Set the switch to show “115” for
voltages in the 100–130 V range.
Set the switch to show “230” for
voltages in the 200–270 V range.
Check to see that the voltage switch
on the back of your computer is
properly set before you plug it in.
If you need to change the setting,
insert a small screwdriver in this
slot and slide the switch.
