Safety Indications
This section provides notes on using your product safely. Read this section carefully to ensure proper and
safe use of the product. For symbols, see "SAFETY INDICATIONS" provided earlier.
General
WARNING
Do not use the product in life-critical applications or applications requiring high reliability.
The product is not intended for integration with or control of facilities or equipment that may affect human
life or that require a high degree of reliability, such as medical equipment, nuclear power facilities or
instruments, aerospace instruments, transportation facilities or instruments. NEC does not assume any
liability for accidents resulting in injury or death, or for any damages to property that may occur as a
result of using the product in such facilities, equipment, or control systems.
Do not use the server if any smoke, odour, or noise is present.
If smoke, odour, or noise is present, immediately turn off the server and disconnect the power plug from
the AC outlet, then contact your service representative. Using the server in such conditions may cause a
fire.
Keep needles or metal objects away from the server.
Do not insert needles or metal objects into ventilation holes or cartridge slot of the server. Doing so may
cause an electric shock.
CAUTION
Keep water or foreign matter away from the server.
Do not let any form of liquid (water etc.) or foreign matter (e.g., pins or paper clips) enter the server.
Failure to follow this warning may cause an electric shock, a fire, or a failure of the server. When such
things accidentally enter the server, immediately turn off the power and disconnect the power plug from
the AC outlet. Do not disassemble the server. Contact your service representative.

v
Power Supply and Power Cord Use
CAUTION
Disconnect the power cord(s) before installing or removing the product in/from the server.
Make sure to power off the server and disconnect the power cord(s) from a power outlet before
installing/removing the product in/from the server, or connecting with the peripheral devices. All voltage is
removed only when the power cords are unplugged.
Do not use any damaged cable.
Make sure the cable condition before connection. Using the damaged connector, bent connector pin, or
dirty connector may cause a fire due to short-circuit.
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 pull the cable when disconnecting the power cord.
When disconnecting the power cord from the server, hold the plug and pull it straight out. Pulling the cord
out by the cable portion could damage the cable to result in an electrical shock hazard or a fire.

vi
Installation, Relocation, Storage, and Connection
CAUTION
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
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 a cable or connector may cause an electric shock or
a fire resulted from a short circuit.
Do not use any unauthorized interface cable.
Use only interface cables authorized by NEC and locate a proper device and connector before
connecting a cable. Using an unauthorized cable or connecting a cable to an improper destination may
cause a short circuit, resulting in a fire.
Also, observe the following notes on using and connecting an interface cable.
Do not step on the cable.
Do not place any object on the cable.
Do not use the server with loose cable connections.
Do not use any damaged cable connector.
Make sure the cable is securely locked with screw.
Do not use or store the product in the place where corrosive gases exist.
Make sure not to locate or use the server in the place where corrosive gases (sulphur dioxide, hydrogen
sulphide, nitrogen dioxide, chlorine, ammonia, ozone, etc) exist.
Also, do not install it in the environment where the air (or dust) includes components accelerating
corrosion (ex. sulphur, sodium chloride) or conductive metals. There is a risk of a fire due to corrosion
and shorts of an internal printed board.
Consult with your service representative for the location appropriate to the server.
Avoid installation in extreme temperature conditions.
Immediately after the server is powered off, its internal components such as hard disk drives are very
hot. Leave the server until its internal components fully cool down before installing/removing any
component.

vii

information or companies' management information) on the removed hard disk to
any third parties.
Data seems to be erased when you empty "Recycle Bin" of Windows or execute
the "format" command of the operating system. However, the actual data remains
written on the hard disk. Data not erased completely may be restored by special
software and used for unexpected purposes.
It is strongly recommended that the software or service (both available at stores)
for data erasure should be used in order to avoid the trouble explained above. For
details on data erasure, ask your sales representative.
NEC assumes no liability for data leakage if the product is transferred to third party
without erasing the data.
Life of BBU
The BBU is equipped with a backup battery. The life of the battery is about 2 years while it varies depending
on the use environment and operating conditions.
Replace the battery with a new one after about two years from the installation of the BBU (the installation
time can be known by the battery label put on the server and the BBU). Contact your service representative
for the replacement
Maintenance Parts
The holding period of maintenance parts of the BBU is five years from the truncation of manufacturing.
Recycle and Disposal
The battery pack of the BBU is equipped with lithium ion battery which is recyclable. To enable such valuable
resources to be reused, contact your service representative or bring it to the nearest recycle agent. For the
removal of the BBU, see "4. Battery Pack Replacement Procedure" in "Chapter 3 - Operation and
Maintenance".

government or your service representative.
Take sufficient note on the handling of the battery pack following "Chapter 3 Operation and Maintenance".
Notice
Dispose of hard disk drives, backup data cartridges, floppy disks and other
writable media (including CD-R/CD-RW) after erasing the data saved in the
media securely on your own responsibility so that the data may not be restored,
replayed, and/or reused by third parties. Take special care for protecting
individual privacy and corporate secret.
