General Precautions
·Follow all caution and warning instructions marked on the equipment and
explained in the accompanying equipment documentation.
Machine Room Environment
·This device is for use only in a machine room or IT room.
 ·Make sure that the area in which you install the system is properly
ventilated and climate-controlled.
·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 object of any kind through openings in the equipment.
Dangerous voltages might be present.
·Conductive foreign object 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 requirement 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.

9
http://www.tyan.com
·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.
·Make sure the full weight of the rack res 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. Product 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 requirement.

10
http://www.tyan.com
Equipment Power Cords
·Use only the power cords and power supply unit 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 environment, you must ground the Green/Yellow
tab on the power cord. If you do not ground the Green/Yellow tab, it can
cause an electrical shock due to high leakage current.
·Do not place object 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 contact, 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 agent.
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.

11
http://www.tyan.com

component.
·Remove all watches, rings, or loose jewelry when working before removing
covers and touching internal component.
·Do not use conductive tools that could bridge live par.
·Use gloves when you remove or replace system component; 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
