Restrictions
This section describes the environmental restrictions and usage of the system equipment and
its peripheral equipment.
Environment for using system
equipment and peripheral equipment

Be sure to house the system equipment in a rack cabinet from Hitachi, and place
it on a level surface. Do not use the system equipment without a rack.
DANGER
Do not remove or install the system equipment in or from the rack cabinet. Always
get help from at least one other person or use tools. If the system equipment has to
be installed on 31U and above of the rack cabinet or it is already installed there, call
for maintenance personnel instead of attempting to install or remove it. Defective
installation may cause the system equipment to fall, resulting in injury or equipment
failure.

In a cold environment, wait 20 to 30 minutes after power-on before operating the
equipment.

In a hot environment, use an air-conditioner and wait until the room temperature
becomes stable before operating the equipment.

Do not use the equipment in a place subject to direct sunlight or heat generated
by a heater or similar equipment.

Do not use the equipment in an extremely dusty environment.

Do not use the equipment in an extremely hot or cold environment, or an
environment where the temperature widely fluctuates.
Do not use the equipment in an extremely humid environment.

Air that contains corrosive gases or salt content chemically corrodes the surface
of the system equipment and the components of its peripheral equipment. The
corrosion increases the contact resistance of electronic components and impairs
the structural strength of movable parts, eventually reducing the reliability of the
system equipment and its peripheral equipment to a large extent. Therefore, a
place free from corrosive gases (particularly sulfur dioxide, hydrogen sulfide,
chlorine gas, and ammonia gas, among others) must be selected for installation.

A lightning strike occurring near the place where the system equipment is being
used or poor power quality may cause the display to power off due to a
temporary blackout or voltage reduction.
If this happens, turn off the power to the system equipment, and turn it on again.
