SAFETY INFORMATION
Before installing and using the Transport GT24, 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 pro-
vided 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 your 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

2.0.1 Before You Begin
This chapter explains how to install the CPU, CPU heatsink,
memory modules, and hard drives. Instructions on inserting a
PCI card are also given.
Take note of the precautions mentioned in this section when
installing your system.
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:
Chapter 2: Setting Up
•A cross head (Phillips) screwdriver
•A grounding strap or an anti-static pad
Most of the electrical and mechanical connections can be disconnected using your fingers. It is recommended that you do
not use needle-nosed pliers to remove connectors as these
can damage the soft metal or plastic parts of the connectors.
Chapter 2: Setting Up17
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 the
Transport GT24 or injury to yourself.
•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.
•Avoid touching motherboard components, IC chips,
connectors, memory modules, and leads.
•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.
•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.
•Leave all components inside the static-proof packag-
ing that they ship with until they are ready for installation.
•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.
Notes:
•All connectors are keyed to only attach one way.
•Always use the correct screw size as indicated in the
procedures.

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 consequences).
If these options are not available for you then Tyan Computer
Corporation can help.Besides designing innovative and quality products for over a decade, Tyan has continuously offered
customers service beyond their expectations. Tyan's website
(www.tyan.com) provides easy-to-access resources such as

Returning Merchandise for Service
During the warranty period, contact your distributor or system
vendor FIRST for any product problems. This warranty only
covers normal customer use and does not cover damages
incurred during shipping or failure due to the alteration, misuse, abuse, or improper maintenance of products.
NOTE: A receipt or copy of your invoice marked with the date
of purchase is required before any warranty service can be
rendered. You may obtain service by calling the manufacturer
for a Return Merchandise Authorization (RMA) number. The
RMA number should be prominently displayed on the outside
of the shipping carton and the package should be mailed prepaid. TYAN will pay to have the board shipped back to you.
