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.
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 your sales representative. Do not attempt to disassemble the server to
replace or recharge the battery by yourself.
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.
Electric shock
The cooling fans, hard disk drives, and power supply unit (only when two power supply units
are installed) are hot-swappable. 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.
