CAUTION
Do not apply any weight on the server when it is extended from the rack
Do not apply force on the server when it is extended from the rack. Doing so cause the frames to bend,
which makes it impossible to be mounted on the rack. It also may cause the server to fall, resulting in
personal injury.
Do not attempt to connect or disconnect the interface cable while the power cord is plugged into
an outlet
Be sure to 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.
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.
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
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 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.
Disconnect the power plug before cleaning the server.
Be 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 of 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.
