Notes on Using Your Server 1-9
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 other
than described in this User's Guide. Failure to follow this instruction may cause
an electric shock or fire as well as malfunctions of the server.
Do not look into the CD-ROM drive.
A laser beam is used in the CD-ROM drive. 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.
The 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 cleaning the server.
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.
CAUTION
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.
