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 batteries.
Your server contains lithium batteries. Do not remove or replace the batteries. If the
battery is incorrectly replaced, it may cause an explosion. Placing the battery close to a
fire or in the water may also cause an explosion.
When the server does not operate appropriately due to the dead lithium batteries,
contact your service representative to replace the battery. Do not disassemble the
server to replace or recharge the battery by yourself.
Disconnect all the power plugs before accessing inside the server, or connecting the
peripherals.
Make sure to power off the server and disconnect the all power plugs from a power
outlet before cleaning or installing/removing internal optional devices (except for
hot-swappable devices). Touching any internal device of the server with its power cords
connected to a power source may cause an electric shock even of the server is
off-powered.
Disconnect all the power plugs 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.
