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 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 use any damaged cable connector.
• 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.
Cleaning and working with internal devices
Do not disassemble, repair, or alter the server.
Never attempt to disassemble, repair, or alter the server on any occasion except as described in
User's Guide. Failure to follow this warning may cause not only malfunction of the server but
also an electric shock or fire.
Risk of explosion if a battery is removed or replaced.
Do not attempt to remove lithium, NiMH, or Li-ion batteries installed in this product by
yourself.
If the product does not work normally due to the dead battery, contact your sales representative.
Placing a battery close to a fire or in the water or replacing it with an incorrect type may cause
an explosion. Dispose of used batteries according to 1.5 Transfer, movement, and disposal.
Disconnect the power plug before cleaning the server.
Be 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. Occasionally disconnect the power plug from the outlet 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.
Pay attention to hot surface.
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.
