1-2 Before You Start

The major component of the subassembly is the chassis, which comes in two mod-
els—8x ISA/ 1 CPUslot or 4 x PCI/ 4 ISA/1 CPU slot Passive Backplane. The chassis
comes pre-assembled with an active matrix LCD, LCD controller, power supply,
keyboard, ventilation fans and internal speaker. To complete the system, you must add a
system board, CPU and peripheral devices.
Before adding these devices, it is important to follow certain basic safety precautions. You
should become familiar with the chassis both externally and internally. And you should also
have the right tools available to you.

1-3 Precautions

1-3-1 Power Connections

The major component of the subassembly is the chassis, which comes in two models— 8x
ISA/ 1 CPUslot or 4 x PCI/ 4 ISA/1 CPU slot Passive Backplane. The chassis comes pre-
assembled with an active matrix LCD, LCD controller, power supply, keyboard, ventilation fans
and internal speaker. To complete the system, you must add a system board, CPU and periph-
eral devices.
Use Supplied Power Cord
The subassembly is shipped with a power cord compatible with the AC wall outlet in your
region.

1-3-2 Non-Autosensing Power Supply

Before plugging in the power cord, examine the power supply to see if you have an
autosensing or non-autosensing power supply.
Autosensing power supplies automatically adjust to the AC constructed of metal and provide
front impact protection for outlet voltage. If your subassembly is shipped with a non-
autosensing power supply, there will be a voltage selector switch located near the AC power
connector. Make sure it' s set to the appropriate voltage setting for your power outlet.

1-3-3 ATX Power Switch

The power supply shipped with the ATX chassis may or may not have an ON/OFF switch. To
power up your system where the power supply has an ON/OFF switch, you must first press the
switch to the ON position and then press the ATX power up/down switch located on the front to
start your system.
The ATX power switch found on the front of the chassis DOES NOT turn off the AC
power. To remove AC power from your system, you must unplug the AC power
cord from the AC outlet or the chassis.
