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 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 CD-ROM drive.
A laser beam used in the CD-ROM 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 and NiMH batteries.
Your server contains lithium and NiMH 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 dead lithium and/or NiMH batteries,
contact your service representative to replace it only with the same or equivalent type
recommended by us. 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.
The server has two power cords.
Make sure to power off the server and disconnect all power plugs from the power outlets before
cleaning or installing/removing internal optional 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.
CAUTION
High temperature
Immediately after the server is powered off, its internal components such as hard disks 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,
esulting in smoke or fire.
r
Protect the unused connectors with a protective cap.
The unused power supply cable connectors are covered with a protective cap to prevent short
circuits and electrical hazards. When removing the power supply cable connector from the
internal devices, attach a protective cap to the connector. Failure to follow this warning may
cause a fire or an electric shock.
Do not touch any electrical component inside the server during the hot-swap replacement.
All power flows inside the server during the hot-swap of replaceable components (PCI add-in
cards, hard disk, cooling fan, and power supply). Do not touch the electrical components inside
the server to avoid an electric shock.
