1-8 Before Using
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 server.
There is a risk of an electric shock or fire as well as malfunction.
Do not look into the DVD-ROM drive.
The DVD-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 server does not work correctly,
contact your sales agent instead of disassembling, replacing or recharging it yourself.
Disconnect the power plugs before cleaning the server.
Even though built-in options for the server can be replaced while the power cords are
connected to power source, be sure to follow the instructions described in this User
’
s
Guide. Do not touch any internal device of the server unless instructed by this User
’
s
Guide. There is a risk of an electric shock.
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 cords connected to 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 completely insert cables and boards.
Completely insert all power cords, interface cables and/or boards. An incompletely
inserted component may cause a contact failure, resulting in fire and/or smoke.
