Cleaning and Handling of Internal Devices

WARNING
Do not disassemble, repair, or alter the server.
Unless described herein, never attempt to disassemble, repair, or alter the
equipment. There is a risk of an electric shock or fire as well as malfunction.
Do not look into the CD-ROM drive.
The CD-ROM drive uses a laser beam. Do not look or insert a mirror inside
while the system is on. A laser beam is invisible; if your eyes get exposed to it,
there is a risk of losing eyesight.
Do not detach a lithium battery yourself.
This equipment has a lithium battery. Do not detach it yourself. If the battery is
exposed to fire or water, it could explode.
When the lithium battery is running down and the equipment does not work
correctly, contact your sales agent instead of disassembling, replacing or
recharging it yourself.
RISK OF EXPLOSION IF BATTERY IS REPLACED WITH INCORRECT TYPE.
DISPOSE OF USED BATTERIES ACCORDING TO THE INSTRUCTION.
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 if 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
High temperature
Immediately after powering off the system, system components such as hard
disk may be very hot. Wait for the server to cool down completely before
adding/removing components.
Make sure to complete installation.
Firmly install all power cords, interface cables and/or boards. An incompletely
installed component may cause a contact failure, resulting in fire and/or smoke.
