Safety Precautions

Warning! Always disconnect the power cord from the chassis before working on
the hardware. Do not reconnect cords 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 equipped with a battery-powered real-time clock circuit.
Batteries are at risk of exploding if incorrectly replaced. Replace only
with the same or equivalent type recommended by the manufacturer.
Discard used batteries according to the manufacturer's instructions.
Caution! New batteries may explode if handled incorrectly. Do not attempt to
recharge, force open, or heat the battery. Replace the battery only with
the same or equivalent type recommended by the manufacturer. Dis-
card used batteries according to the manufacturer's instructions.

Jumper Settings

This section provides instructions on how to configure the motherboard by setting the
jumpers. The default motherboard settings and options for each jumper are also
explained.
1.8.1

How to Set Jumpers

Users can configure the motherboard according to specific application requirements
by setting the jumpers. A jumper is a metal bridge used to close an electrical circuit.
Jumpers 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, remove the clip.
Some jumpers consist of three pins labeled 1, 2, and 3. In such cases, connect either
Pins 1 and 2, or Pins 2 and 3. A pair of needle-nose pliers may be necessary for set-
ting jumpers.
