Cleaning And Working With Internal Devices - NEC express5800 A2010b User Manual

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 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.
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
Electric shock
The cooling fans, hard disk drives, and power supply unit (only when two servers are installed) support
hot swapping. If replacing a component when the electrical current is being supplied, use extreme caution
not to get electric shock by touching terminal parts of the internal components.
