Observe all warnings on the product and in the operating instructions.
To reduce the risk of bodily injury, electric shock, fire and damage to
the equipment, observe all precautions included in this guide.
You must become familiar with the safety information in this guide
before you install, operate, or service TYAN products.
Symbols on Equipment
Caution. This symbol indicates a potential
hazard. The potential for injury exists if
cautions are not observed. Consult equipment
documentation for specific details.
Warning. This symbol indicates the presence
of hazardous energy circuits or electric shock
hazards. Refer all servicing to qualified

General Precautions
· Follow all caution and warning instructions marked on the equipment
and explained in the accompanying equipment documentation.

Machine Room Environment

· Make sure that the area in which you install the system is properly
ventilated and climate-controlled.
7
http://www.tyan.com
· Ensure that the voltage and frequency of your power source match the
voltage and frequency inscribed on the electrical rating label of the
equipment.
· Do not install the system in or near a plenum, air duct, radiator, or heat
register.
· Never use the product in a wet location.
Equipment Chassis
· Do not block or cover the openings to the system.
· Never push objects of any kind through openings in the equipment.
Dangerous voltages might be present.
· Conductive foreign objects can produce a short circuit and cause fire,
electric shock, or damage to your equipment.
· Lift equipment using both hands and with your knees bent.
Equipment Racks
To avoid injury or damage to the equipment:
· Observe local occupational health and safety requirements and
guidelines for manual materials handling.
· Do not attempt to move a rack by yourself; a minimum of two people
are needed to move a rack.
· Do not attempt to move a fully loaded rack. Remove equipment from
the rack before moving it.
· Do not attempt to move a rack on an incline that is greater than 10
degrees from the horizontal.
· Make sure the rack is properly secured to the floor or ceiling.
· Make sure the stabilizing feet are attached to the rack if it is a
single-rack installation.
· Make sure racks are coupled together if it is a multiple-rack installation.
· Make sure the rack is level and stable before installing an appliance in
the rack.
· Make sure the leveling jacks are extended to the floor.
8
http://www.tyan.com
· Make sure the full weight of the rack rests on the leveling jacks.
· Always load the rack from the bottom up. Load the heaviest component
in the rack first.
· Make sure the rack is level and stable before pulling a component out
of the rack.
· Make sure only one component is extended at a time. A rack might
become unstable if more than one component is extended.
To avoid damage to the equipment:
· The rack width and depth must allow for proper serviceability and cable
management.
· Ensure that there is adequate airflow in the rack. Improper installation
or restricted airflow can damage the equipment.
· The rack cannot have solid or restricted airflow doors. You must use a
mesh door on the front and back of the rack or remove the doors to
ensure adequate air flow to the system.
· If you install the Model in a rack, do not place equipment on top of the
unit. It will cause restricted airflow and might cause damage to the
equipment.
· Make sure the product is properly matted with the rails. Products that
are improperly matted with the rails might be unstable.
· Verify that the AC power supply branch circuit that provides power to
the rack is not overloaded. This will reduce the risk of personal injury, fire,
or damage to the equipment. The total rack load should not exceed 80
percent of the branch circuit rating. Consult the electrical authority having
jurisdiction over your facility wiring and installation requirements.
Equipment Power Cords
· Use only the power cords and power supply units provided with your
system. The system might have one or more power cords.
· Plug the power cord into a grounded (earthed) electrical outlet that is
easily accessible at all times.
· In all European electrical environments, you must ground the
Green/Yellow tab on the power cord. If you do not ground the
9
http://www.tyan.com
Green/Yellow tab, it can cause an electrical shock due to high leakage
currents.
· Do not place objects on AC power cords or cables. Arrange them so
that no one might accidentally step on or trip over them.
· Do not pull on a cord or cable. When unplugging from the electrical
outlet, grasp the cord by the plug.
· To reduce the risk of electrical shock, disconnect all power cords before
servicing the appliance.
Equipment Batteries
· The system battery contains lithium manganese dioxide. If the battery
pack is not handled properly, there is risk of fire and burns.
· Do not disassemble, crush, puncture, short external contacts, or
dispose of the battery in fire or water.
· Do not expose the battery to temperatures higher than 60°C (140°F).
· The system battery is not replaceable. If the battery is replaced by an
incorrect type, there is danger of explosion. Replace the battery only with a
spare designated for your product.
· Do not attempt to recharge the battery.
· Dispose of used batteries according to the instructions of the
manufacturer. Do not dispose of batteries with the general household
waste. To forward them to recycling or proper disposal, use the public
collection system or return them to TYAN, your authorized TYAN partner,
or their agents.
Equipment Modifications
· Do not make mechanical modifications to the system. TYAN is not
responsible for the regulatory compliance of TYAN equipment that has
been modified.
Equipment Repairs and Servicing
· The installation of internal options and routine maintenance and service
of this product should be performed by individuals who are knowledgeable
10
http://www.tyan.com
about the procedures, precautions, and hazards associated with
equipment containing hazardous energy levels.
· Do not exceed the level of repair specified in the procedures in the
product documentation. Improper repairs can create a safety hazard.
· Allow the product to cool before removing covers and touching internal
components.
· Remove all watches, rings, or loose jewelry when working before
removing covers and touching internal components.
· Do not use conductive tools that could bridge live parts.
· Use gloves when you remove or replace system components; they can
become hot to the touch.
· If the product sustains damage requiring service, disconnect the product
from the AC electrical outlet and refer servicing to an authorized service
provider. Examples of damage requiring service include:

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:
 A cross head (Phillips) screwdriver
 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.
33
http://www.tyan.com
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 GN70-B8236 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 packaging 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.
CAUTION: Please note that the following illustrations may not look
exactly like the rackmount server you purchased. Therefore, the
illustrations should be held for your reference only.

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

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 manufa-cturer for a Return Merchandise Authorization (RMA) nu-mber. 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.
