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 look into the optical disk drive
A laser beam used in the optical disk is harmful to the eyes. Do not look into or insert a mirror into the drive
while the drive is powered on. If a laser beam (which is invisible) enters your eyes, you may lose your
eyesight.
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.
CAUTION
High temperature
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
