Using Your Computer 1-13
Voltage Selector Switch
The voltage selector switch sets the voltage for your system
to 115 volts (V) or 230 V.
!
CAUTION: Set the switch correctly for
the voltage in your area. Most wall outlets in the
United States and Canada are 115 volts. Outlets
in Europe, Australia, and Asia (except Taiwan) are
230 volts. Taiwan uses 115-volt outlets.
System Power Socket
The system power socket is the connector for the system
unit power cord. This is the connection for alternating
current (AC) from your wall outlet to the system unit.
Expansion Slot Covers
The expansion slot covers are removable, allowing the
installation of 8-bit or 16-bit industry-standard architecture
(ISA) or 32-bit PCI expansion boards to the system.
The desktop system has four expansion slots: three ISA
slots and one shared PCI/ISA slot for a PCI or an ISA
board. The minitower system has five expansion slots: four
ISA slots and one shared PCI/ISA.
See “Boards” in Chapter 5 for information about installing
an expansion board.
