CE Statement
Warning: This is a Class A product. In residential environment, this product may cause radio
interference, in which case the user may be required to take adequate measures (EN55022).
CLASS 1
LASER PRODUCT
NOTE: This product provides resistance against hardware faults with its redundant hardware
modules. However, this does not mean complete fault-tolerance is assured. For example,
there is a risk of system down when:
– A fatal fault occurs in software.
– Both modules within a redundant hardware pair break down.
– A fatal fault occurs in a non-redundant component, such as the clock generator circuitry
or the interconnect backplane.
– The entire system is cut off from AC power.

1-6 Precautions for Use
Use of Power Supply and Power Cord
WARNING
Do not handle a power plug with a wet hand.
Do not plug/unplug a power cord with a wet hand. There is a risk of an electric
shock.
Do not connect the ground wire to a gas pipe.
Never connect the ground wire to a gas pipe. There is a risk of a gas explosion.
CAUTION
Do not plug the attached cord in a nonconforming outlet.
Use a wall outlet with specified voltage and power type. There is a risk of a fire
or current leakage.
Avoid installing the equipment where you may need an extension cord. If the
cord that does not meet the power specifications, there is a risk of overheating
that could lead to a fire.

If the rated current is exceeded, there is a risk of overheating that could lead to
a fire.
Do not plug the cord insecurely.
Insert the plug firmly into an outlet. There is a risk of heat or fire due to poor
contact. If dust settles on the slots and it absorbs moisture, there is also a risk
of heat or fire.
Do not use nonconforming power cords.
AC cord is to spend the thing of the next specifications.

1-8 Precautions for Use
Do not connect any interface cable with the power cord of the server plugged to
a power source.
Make sure to power off the server and unplug the power cord from a power
outlet before installing/removing any optional internal device or
connecting/disconnecting any interface cable to/from the server. If the server is
off-powered but its power cord is plugged to a power source, touching an
internal device, cable, or connector may cause an electric shock or a fire
resulted from a short circuit.
Do not use any non-designated interface cable.
Use only interface cables designated by NEC; identify which component or
connector to attach beforehand. If you use a wrong cable or make a wrong
connection, there is a risk of short-circuit that could lead to a fire.
You also have to observe the following prohibitions about handling and
connecting interface cables:
Do not use any damaged cable connector.
Do not step on the cable.
Do not place any object on the cable.
Do not use the equipment with loose cable connections.
Do not use any damaged cable.
CAUTION
Cleaning and Handling of Internal Devices
WARNING
Do not disassemble, repair, or alter the server.
Unless described herein, never attempt to disassemble, repair, or alter the
equipment. There is a risk of an electric shock or fire as well as malfunction.
Do not look into the CD-ROM drive.
The CD-ROM drive uses a laser beam. Do not look or insert a mirror inside
while the system is on. A laser beam is invisible; if your eyes get exposed to it,
there is a risk of losing eyesight.
Do not detach a lithium battery yourself.
This equipment has a lithium battery. Do not detach it yourself. If the battery is
exposed to fire or water, it could explode.
Precautions for Use 1-9
When the lithium battery is running down and the equipment does not work
correctly, contact your sales agent instead of disassembling, replacing or
recharging it yourself.
RISK OF EXPLOSION IF BATTERY IS REPLACED WITH INCORRECT TYPE.
DISPOSE OF USED BATTERIES ACCORDING TO THE INSTRUCTION.
Disconnect the power plug before cleaning the server.
Make sure to power off the server and disconnect the power plug from a power
outlet before cleaning or installing/removing internal optional devices. Touching
any internal device of the server with its power cord connected to a power
source may cause an electric shock even if the server is off-powered.
Disconnect the power plug from the outlet occasionally and clean the plug with
a dry cloth. Heat will be generated if condensation is formed on a dusty plug,
which may cause a fire.
CAUTION
High temperature
Immediately after powering off the system, system components such as hard
disk may be very hot. Wait for the server to cool down completely before
adding/removing components.
Make sure to complete installation.
Firmly install all power cords, interface cables and/or boards. An incompletely
installed component may cause a contact failure, resulting in fire and/or smoke.
1-10 Precautions for Use
Protect the unused connectors with the protective cap.
The unused power cord connectors are covered with the protective cap to
prevent short circuits and electrical hazards. When removing the power cord
connector from the internal devices, attach the protective cap to the connector.
Failure to follow this warning may cause a fire or an electric shock.
During Operation
Do not pull out a device during operation.
Do not pull out or remove a device while it works. There is a risk of malfunction
and injuries.
