1-4. SAFETY PRECAUTIONS
Following messages are safety reminders on how to protect your systems from
damages. And thus, helps you lengthen the life cycle of the system.
1. Check the Line Voltage
a. The operating voltage for the power supply should cover the range of
100VAC-240VAC, otherwise the system may be damaged.
2. Environmental Conditions
a. Place your PS-8851A on a sturdy, level surface. Make sure there is
enough space for each side so that user could access it very easily.
b. Do not install PS-8851A in the place that is extremely hot or cold.
c. Avoid exposure to sunlight for a long period of time (for example in a
closed car in summer time. Also avoid the system from any heating
device.). Or do not use PS-8851A when it‘s been left outdoors in a cold
winter day.
d. Bear in mind that the operating ambient temperature is from 0°C up to
+40°C.
e. Avoid moving the system rapidly from a hot place to a cold place or
vice versa because condensation may come from inside of the system.
f. Place PS-8851A against strong vibrations, which may cause hard disk
failure.
g. Do not place the system too close to any radio active device. Radio-
active device may cause interference.
h. Always shutdown the operation system before turning off the power.
3. Handling
a. Avoid putting heavy objects on top of the system.
b. Do not turn the system upside down. This may cause the floppy drive
and hard drive to mal-function.
c. Do not remove the diskette from the Floppy drive while the light is still
on. If you remove the diskette while the light is on, you may damage
the information on the diskette.
4. Good Care
a. When the outside of the case is stained, remove the stain with neutral
washing agent with a dry cloth.
b. Never use strong agents such as benzene and thinner to clean the system.
c. If heavy stains are present, moisten a cloth with diluted neutral washing

Chapter 1 Introduction
PS-8851A USER ′ S MANUAL Page: 1-9
agent or with alcohol and then wipe thoroughly with a dry cloth.
d. If dust has been accumulated on the outside, remove it by using a special
made vacuum cleaner for computers.

2-3. HOW TO SET THE JUMPERS
You can configure your board by setting the jumpers. Jumper is consists of
two or three metal pins with a plastic base mounted on the card, and by
using a small plastic "cap", Also known as the jumper cap (with a metal
contact inside), you are able to connect the pins. So you can set-up your
hardware configuration by "opening"or "closing"pins.
The jumper can be combined into sets that called jumper blocks. When the
jumpers are all in the block, you have to put them together to set up the
hardware configuration. The figure below shows how this looks like.
JUMPERS AND CAPS
If a jumper has three pins for example, labelled PIN1, PIN2, and PIN3. You
can connect PIN1 & PIN2 to create one setting and shorting. You can either
connect PIN2 & PIN3 to create another setting. The same jumper diagrams
are applied all through this manual. The figure below shows what the manual
diagrams look and what they represent.
