SAFETY INFORMATION

Before installing and using TYAN GT20-B5502, take note of the following
precautions:

·Read all instructions carefully.

·Do not place the unit on an unstable surface, cart, or stand.

·Do not block the slots and opening on the unit, which are provided for

ventilation.

·Only use the power source indicated on the marking label. If you are not
sure, contact the power company.

·The unit uses a three-wire ground cable, which is equipped with a third
pin to ground the unit and prevent electric shock. Do not defeat the
purpose of this pin. If you outlet does not support this kind of plug, contact
your electrician to replace your obsolete outlet.

·Do not place anything on the power cord. Place the power cord where it
will not be in the way of foot traffic.

·Follow all warnings and cautions in this manual and on the unit case.

·Do not push objects in the ventilation slots as they may touch high

voltage components and result in shock and damage to the components.

· When replacing parts, ensure that you use parts specified by the
manufacturer.

·When service or repairs have been done, perform routine safety checks
to verify that the system is operating correctly.

·Avoid using the system near water, in direct sunlight, or near a heating
device.

·Cover the unit when not in use.

Chapter 2: Setting Up

2.0.1 Before you Begin

This chapter explains how to install the CPUs, CPU heatsinks, memory modules,
and hard drives. Instructions on inserting add on
cards are also given.

2.0.2 Work Area

Make sure you have a stable, clean working environment. Dust and dirt can get
into components and cause malfunctions. Use containers to keep small
components separated. Putting all small components in separate containers
prevents them from becoming lost. Adequate lighting and proper tools can
prevent you from accidentally damaging the internal components.

2.0.3 Tools

The following procedures require only a few tools, including the following:

z A cross-head (Phillips) screwdriver

z A grounding strap or an anti-static pad

Most of the electrical and mechanical connections can be disconnected with
your hands. It is recommended that you do not use pliers to remove connectors
as it may damage the soft metal or plastic parts of the connectors.

http://www.tyan.com

24

2.0.4 Precautions

Components and electronic circuit boards can be damaged by discharges of
static electricity. Working on a system that is connected to a power supply can
be extremely dangerous. Follow the guidelines below to avoid damage to
GT20-B5502 or injury to yourself.

z Ground yourself properly before removing the top cover of the system.

Unplug the power from the power supply and then touch a safely grounded
object to release static charge (i.e. power supply case). If available, wear a
grounded wrist strap. Alternatively, discharge any static electricity by
touching the bare metal chassis of the unit case, or the bare metal body of
any other grounded appliance.

z Avoid touching motherboard components, IC chips, connectors, memory

modules, and leads.

z The motherboard is pre-installed in the system. When removing the

motherboard, always place it on a grounded anti-static surface until you
are ready to reinstall it.

z Hold electronic circuit boards by the edges only. Do not touch the

components on the board unless it is necessary to do so. Do not flex or
stress circuit boards.

z Leave all components inside the static-proof packaging that they ship with

until they are ready for installation.

z After replacing optional devices, make sure all screws, springs, or other

small parts are in place and are not left loose inside the case. Metallic
parts or metal flakes can cause electrical shorts.

NOTE:

All connectors are keyed to only attach one way.
All use the correct screw size as indicated in the procedures.

Appendix III: Technical Support

If a problem arises with your system, you should first turn to your dealer for
direct support. Your system has most likely been configured or designed by
them and they should have the best idea of what hardware and software your
system contains. Hence, they should be of the most assistance for you.
Furthermore, if you purchased your system from a dealer near you, take the
system to them directly to have it serviced instead of attempting to do so
yourself (which can have expensive consequence).

If these options are not available for you then MiTAC International Corporation
can help. Besides designing innovative and quality products for over a decade,
MiTAC has continuously offered customers service beyond their expectations.
TYAN’s website (http://www.tyan.com) provides easy-to-access resources
such as in-depth Linux Online Support sections with downloadable Linux
drivers and comprehensive compatibility reports for chassis, memory and
much more. With all these convenient resources just a few keystrokes away,
users can easily find their latest software and operating system components to
keep their systems running as powerful and productive as possible. MiTAC
also ranks high for its commitment to fast and friendly customer support
through email. By offering plenty of options for users, MiTAC serves multiple
market segments with the industry’s most competitive services to support
them.
