– Important Safety Instructions, Care and Handling
Important Safety Instructions, Care and Handling
Before starting, take a few minutes to read this manual.
Read all of these instructions and save this manual for
later reference.
Protect the disk array system from extremely high or low
temperatures. Let the disk array system warm (or cool)
to room temperature before using it.
Protect the disk array system from being bumped or
dropped. Do not place the disk array system on an
unstable cart, stand, or table. It may fall, causing serious
damage to the product.
Keep the disk array system away from magnetic forces.
Do not use the disk array system near water.
Keep the disk array system away from dust, sand, or dirt.
Gaps and openings in the cabinet are provided for venti-
lation. Never block or cover these openings, because
the disk array system may overheat and become unreli-
able. Don’t place the disk array system on a bed, sofa,
rug, or other similar surface.
Do not place the disk array system near or over a radia-
tor or other heat source.
Refer to the rating plate for the correct voltage and
ensure that the appliance voltage corresponds to the
supply voltage.

Preface
– Important Safety Instructions, Care and Handling
The appliance must be grounded. The disk array system
is equipped with a 3-wire grounded type of power cord.
This power cord will only fit into a grounded type of
power outlet.
If an extension cord or a power center is used with the
disk array system, make sure that the total current con-
sumption of all products plugged into the wall outlet
does not exceed the ampere rating.
Do not place the disk array system where the cord will
be walked on.
Never push any kind of object into the disk array system
through cabinet gaps and openings, since they may
touch dangerous voltage points and cause a risk of fire
or electric shock.
Unplug the power cord from the wall outlet before clean-
ing. Keep the disk array system dry. Do not use liquid
cleaners, aerosol cleaners, or a wet cloth. Use a damp
cloth for cleaning.
Except as specifically explained in this User Manual, do
not attempt to service the disk array system by yourself.
Opening or removing the covers may expose you to
dangerous voltages.
Unplug this product from the wall outlet and refer servic-
ing to qualified service personnel under the following
conditions.
• If the disk array system has been exposed to
water or any liquid.
• If the disk array system has been dropped or the
cabinet damaged.
Users should not remove the cover.
Disconnect all power supply cords before servicing.

Preface
– Important Safety Instructions, Care and Handling
Placement Notes
• The disk array system LCD panel can be damaged by exposure to
direct sunlight. Limit exposure to subdued or indirect sunlight only.
• The disk array system should be used only in clean environments
that are free from airborne contaminants such as dust, dirt, and
smoke. Excessive moisture or oil particles in the air can also hinder
disk array system performance.
• To reduce the possibility of data errors caused by electromagnetic
interference, locate the disk array system at least five feet away
from electrical appliances and equipment that generates magnetic
fields.
Power Supply Safety Notes
• To avoid electric shocks, do not use an extended power cord or an
outlet that does not match the disk array system plug or leaves the
plug exposed.
• The disk array system has a 3-wire grounded plug. The third pin
connects to ground; do not remove it.
• If the power cord or plug is damaged or worn, unplug it immediately
and contact a qualified service technician for maintenance.
• To avoid fire or electric shocks, do not overload electric power out-
lets.
CAUTION : MULTIPLE POWER SOURCES
Disconnect all AC power cords to completely power from the unit
CAUTION
Risk of explosion if battery is replaced by an incorrect type.
Dispose of used batteries according to the instructions.
CAUTION
The thumbscrews on the rear surface shall be secured by the screw-
driver, which cannot be loosened by bare hands to prevent the uninten-
tional access to the hazardous parts inside the equipment.
