1-6 Notes on Using Your Server

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 other
than described in this manual. Failure to follow this instruction may cause an
electric shock or fire as well as malfunctions of the server.
Do not look into the optical disk drive.
A laser beam used in the optical disk drive is harmful to the eyes. Do not look
into or insert a mirror into the drive while the drive is powered. If a laser beam is
caught in your eyes, you may lose your eyesight (the laser beam is invisible).
Do not remove the lithium battery.
Your server contains the lithium battery. Do not remove the battery. Placing the
lithium close to a fire or in the water may cause an explosion.
When the server does not operate appropriately due to the dead lithium battery,
contact your service representative. Do not disassemble the server to replace or
recharge the battery by yourself.
Disconnect the power plug before accessing inside the server, or connecting the
peripherals.
Make 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 of the server is off-powered.
Disconnect the power plug from the outlet occasionally 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.
Avoid installation in extreme temperature conditions.
Immediately after the server is powered off, its internal components such as
hard disk drives are very hot. Leave the server until its internal components fully
cool down before installing/removing any component.
Make sure to complete board installation.
Always install a board firmly. An incompletely installed board may cause a
contact failure, resulting in smoking or fire.
Protect the unused connectors with the protective cap.
The unused power supply cable connectors are covered with the protective cap
to prevent short circuits and electrical hazards, when removing the power supply
cable connector from the install devices, attach the protective cap to the
connector. Failure to follow this warning may cause a fire or an electric shock.
