SAFETY INFORMATION
Before installing and using FT48-B7025, 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 pur-
-pose 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 th e p o wer cord where i t
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 volta-
-ge components and result in shock and damage to the components.
·When replacing parts, ensure that you use parts specified by the manuf-
-acturer.
·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, includin g 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 disconn e-
-cted 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
26
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 FT48-B7025 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 loos e 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.

2.1.3 Installing the Memory
Follow these instructions to install the memory modules onto the
motherboard.
1. Locate the memory slots on the motherboard.
2. Press the memory slot locking levers in the direction of the arrows
as shown in the following illustration.
3. Align the memory module with the slot. When inserted properly,
the memory slot locking levers lock automatically onto the
indentations at the ends of the module.

Note:
1). For the DIMM number please refer to the motherbo ard
placement in “2.3 - Board Parts, Jumpers and
Connectors” for memory installation.
2). Refer to the memory population option table for
recommended memory installation instruction.

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 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
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 the latest software and operating system components to keep their systems
running as powerful and productive as possible. TYAN also ra nks high for its
commitment to fast and friendly customer support through email. By offering
plenty of options for users, TYAN serves multiple market segments with the
industry's most competitive services to support them.
"TYAN's tech support is some of the most impressive we've seen, with
great response time and exceptional organization in general"
