Conventions for Alert Messages
This manual uses the following conventions to show alert messages, which are
intended to prevent injury to the user or bystanders as well as property damage, and
important messages that are useful to the user.
WARNING:
This indicates a hazardous situation that could result in death or serious personal
injury (potential hazard) if the user does not perform the procedure correctly.
CAUTION:
This indicates a hazardous situation that could result in minor or moderate personal
injury if the user does not perform the procedure correctly. This signal also indicates
that damage to the product or other property may occur if the user does not perform
the procedure correctly.
IMPORTANT:
This indicates information that could help the user to use the product more
effectively.

Preface xxv
Caution – The CAUTION signal indicates a hazardous situation could result in
minor or moderate personal injury if the user does not perform the procedure
correctly. This signal also indicates that damage to the product or other property
may occur if the user does not perform the procedure correctly.
Task Warning
Normal
operation
Equipment damage
Be sure to follow the precautions below when installing the main unit.
Otherwise, the equipment may be damaged.
• Do not block ventilation slits.
• Avoid installing the equipment in a place exposed to direct sunlight or
near equipment that becomes extremely hot.
• Avoid installing the equipment in a dusty place or a place directly
exposed to corrosive gas or salty air.
• Avoid installing the equipment in a place exposed to strong vibration.
Also, install the equipment on a level surface so that it is stable.
• The equipment can be grounded using shared grounding. However, the
grounding method varies with the building where it is installed. Be sure
to confirm the related standards to ground the equipment correctly.
• Do not run any cable beneath any equipment. Also, prevent cables from
becoming taut. Never disconnect any power cord from the equipment
while power is being supplied to the equipment.
• Do not place anything on top of the main unit. Do not use the main unit
as a workspace.
• Avoid exposing the equipment to rapid changes in the ambient
temperature, such as a rapid increase during transport in winter. A rapid
increase in the ambient temperature causes moisture to condense in the
equipment. Use the equipment only after the difference between its
temperature and the ambient temperature is negligible.
• Avoid installing the equipment near a copy machine, air conditioner, or
welding machine, which is noisy.
• Take preventive action to minimize static electricity at the installation
location. Note that static electricity is easily generated in some carpets
and can cause the equipment to malfunction.
• Confirm that the power supply voltage and frequency during operation
match the rated values indicated on the equipment.
• Do not insert any object into an opening in the equipment. Components
inside the equipment use high voltage. Conductive foreign matter, such
as a metal object, inserted into the equipment, may cause a short circuit
between components, resulting in fire, electric shock, or equipment
damage.
• For maintenance of the equipment, contact your authorized service
personnel.

operation panel is turned off. Be sure to confirm that the POWER LED is
off before turning off the main power (uninterruptible power supply
[UPS], power distribution box, etc.).
If necessary, back up files before turning off the system power.
Data destruction
Do not forcibly stop a domain that is operating normally. Otherwise, data
may be destroyed.
Data destruction
Do not disconnect the power cord from the AC power input while power
is being supplied. Otherwise, data stored on hard disk units may be
destroyed.
