Safety Precautions
Warning! Always completely disconnect the power cord from the chassis when
working with the hardware. Do not connect devices while the power is
on. Sensitive electronic components can be damaged by sudden power
surges. Only experienced electronics personnel should open the PC
chassis.
Caution! Always ground yourself to remove any static charge before touching the
motherboard. Modern electronic devices are very sensitive to electro-
static discharges. As a safety precaution, use a grounding wrist strap at
all times. Place all electronic components on a static-dissipative surface
or in a static-shielded bag when not in the chassis.
Caution! The computer is provided with a battery-powered real-time clock circuit.
There is a danger of explosion if the battery is incorrectly replaced.
Replace only with the same or equivalent type recommended by the
manufacturer. Discard used batteries according to the manufacturer's
instructions.
Caution! There is a danger of a new battery exploding if incorrectly installed. Do
not attempt to recharge, force open, or heat the battery. Replace the
battery only with the same or equivalent type recommended by the man-
ufacturer. Discard used batteries according to the manufacturer's
instructions.

Jumper Options
This section provides instructions on how to configure the motherboard by setting
jumpers, and also outlines the default motherboard settings and options for each
jumper.
1.8.1
Setting Jumpers
The motherboard can be configured according to the application requirements with
the setting of jumpers. A jumper is a metal bridge used to close an electrical circuit.
Jumpers typically consist of two metal pins and a small metal clip (often protected by
a plastic cover) that slides over the pins to connect them. To "close" (or turn ON) a
jumper, connect the pins with the clip. To "open" (or turn OFF) a jumper, simply
remove the clip. Some jumpers comprise a set of three pins, labeled 1, 2, and 3. With
these jumpers, simply connect either Pins 1 and 2, or Pins 2 and 3. A pair of needle-
nose pliers may be necessary for setting jumpers.
