Safety notes
This section provides notes on using the server safely. Read this section carefully to ensure proper and safe use
of the server. For symbols, see Safety precautions.
General
WARNING
Do not use the server for services where human life may be at stake or high reliability is required.
This server is not intended for use in medical, nuclear, aerospace, mass transit or other applications where
human life may be at stake or high reliability is required, nor is it intended for use in controlling such
applications. We disclaim liability for any personal injury and property damages caused by such use of this
server.
Do not use the server if any smoke, odor, or noise is present.
If smoke, odor, or noise is present, immediately turn off the server and disconnect the power plug from the
outlet, then contact the store where you purchased the product or your maintenance service company.
Using the server in such conditions may cause a fire.
Do not insert needles or metal objects.
Do not insert needles or metal objects into ventilation holes in the server or openings in the optical disk
drive. Doing so may cause an electric shock.
CAUTION
Keep water or foreign matter away from the server.
Do not let any liquid such as water or foreign materials including pins or paper clips enter the server.
Failure to follow this warning may cause an electric shock, a fire, or failure of the server. When such things
accidentally enter the server, immediately turn off the power and disconnect the power plug from the
outlet. Do not disassemble the server, and contact the store where you purchased the product or your
maintenance service company.

Precautions for Use (Be Sure to Read)
Express5800/T110g-S User’s Guide 17
Power supply and power cord use
WARNING
Do not hold the power plug with a wet hand.
Do not disconnect/connect the plug while your hands are wet. Failure to follow this warning may cause an
electric shock.
Do not connect the ground wire to a gas pipe.
Never connect the ground wire to a gas pipe. Failure to follow this warning may cause a gas explosion.
CAUTION
Plug in to a proper power source.
Use a grounded outlet and observe the specified voltage. Use of an improper power source may cause a
fire or a power leak.
Do not install the server where you need an extension cord. Use of a cord that does not meet the power
specifications of the server may heat up the cord and cause a fire.
If you want to use an AC cord set with a ground wire of class OI, be sure to connect the ground wire before
inserting the power plug into the outlet. Before disconnecting the ground wire, be sure to disconnect the
power plug from the output.
Do not connect many cords into a single outlet by using extension cords.
The electric current exceeding the rated flow overheats the outlet, which may cause a fire.
Do not pull out a cable by gripping the cable part.
Pull a cable straight out by gripping the connector part. Pulling a cable by gripping the cable part or
applying extra pressure to the connector part may damage the cable part, which may cause a fire or
electric shock.
Insert the power plug into the outlet as far as it goes.
Heat generation resulting from a halfway inserted power plug (imperfect contact) may cause a fire. Heat
will also be generated if condensation is formed on dusty blades of the halfway inserted plug, increasing
the possibility of fire.

A place exposed to direct sunlight
An unstable place
Do not use the server in an environment where corrosive gas is present
Do not install the server in a place subject to corrosive gases including sodium chloride, sulfur dioxide,
hydrogen sulfide, nitrogen dioxide, chlorine, ammonia, or ozone. Do not install the server in an
environment that contains dust, chemicals that accelerate corrosion such as NaCl or sulfur, or conductive
materials. Failure to follow this warning may cause the wiring on the printed wiring board to short-circuit,
leading to fire. If you have any questions, contact the store where you purchased the product or a
maintenance service company.
Do not connect or disconnect any interface cable with the power cord of the server plugged to a
power source.
Be 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.
Use only the specified interface cable.
Use only interface cables provided by NEC and locate a proper device and connector before connecting a
cable. Using an authorized cable or connecting a cable to an improper destination may cause a short
circuit, resulting in a fire.

Cleaning and working with internal devices
WARNING
Do not disassemble, repair, or alter the server.
Never attempt to disassemble, repair, or alter the server on any occasion except as described in this
document. Failure to follow this warning may cause not only malfunction of the server but also an electric
shock or fire.
Do not look into the optical disk drive
A laser beam used in the optical disk is harmful to the eyes. Do not look into or insert a mirror into the drive
while the drive is powered on. If a laser beam (which is invisible) enters your eyes, you may lose your
eyesight.
Do not attempt to remove lithium, NiMH, or Li-ion batteries.
The server contains the lithium, NiMH, or Li-ion battery (some optional devices have a lithium, NiMH, or
Li-ion battery installed). Do not remove the battery. Placing a battery close to a fire or in the water may
cause an explosion.
When the server does not operate appropriately due to the dead battery, contact the store you purchased
the product or your maintenance service company. Do not attempt to disassemble the server to replace or
recharge the battery by yourself.
CAUTION
High temperature
Components including internal Hard Disk Drives in the server are extremely hot just after the server is
turned off. Allow the surface to cool before installing/removing.
Secure cables or cards in place
Be sure to secure the power cord, interface cables, and cards in place. Incomplete installation causes a
loose connection, resulting in smoke or fire
