Precautions for Use 1-7
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 optical disk drive.
The optical disk 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 are exposed to
the laser beam, there is a risk of losing eyesight.
Do not remove the lithium and NiMH (or Li-Ion) batteries.
Your server contains the lithium and NiMH (or Li-Ion) batteries. Do not remove
the battery. Danger of explosion if the battery is incorrectly replaced.
Placing the battery close to a fire or in the water may cause an explosion. When
the server does not operate appropriately due to the dead lithium and NiMH (or
Li-Ion) batteries, contact your service representative to replace only with the
same or equivalent type recommended by NEC. Do not disassemble the server
to replace or recharge the battery by yourself.
Caution for electric shock
You can replace internal, optional devices while the equipment is powered-on.
However, carefully follow the instructions on this guide when you do so. If you
touch the internal devices other than the ones described in this guide, there is a
risk of electrical shock.
Make sure to power off the equipment and disconnect the power plug from a
power outlet before cleaning or installing/removing internal optional devices.
Touching any internal device of the equipment 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.
