When you handle options or CRUs, or perform any work inside the computer,
take the following precautions to avoid static-electricity damage:
v Limit your movement. Movement can cause static electricity to build up
around you.
v Always handle components carefully. Handle adapters, memory modules,
and other circuit boards by the edges. Never touch exposed circuitry.
v Prevent others from touching components.
v When you install a static-sensitive option or CRU, touch the static-protective
package containing the part to a metal expansion-slot cover or other
unpainted metal surface on the computer for at least two seconds. This
reduces static electricity in the package and your body.
v When possible, remove the static-sensitive part from the static-protective
packaging and install the part without setting it down. When this is not
possible, place the static-protective packaging on a smooth, level surface and
place the part on it.
v Do not place the part on the computer cover or other metal surface.
Power cords and power adapters
Use only the power cords and power adapters supplied by the product
manufacturer.
The power cords shall be safety approved. For Germany, it shall be H05VV-F,
3G, 0.75 mm
2
, or better. For other countries, the suitable types shall be used
accordingly.
Never wrap a power cord around a power adapter or other object. Doing so
can stress the cord in ways that can cause the cord to fray, crack, or crimp.
This can present a safety hazard.
Always route power cords so that they will not be walked on, tripped over, or
pinched by objects.
Protect power cord and power adapters from liquids. For instance, do not
leave your power cord or power adapter near sinks, tubs, toilets, or on floors
that are cleaned with liquid cleansers. Liquids can cause a short circuit,
particularly if the power cord or power adapter has been stressed by misuse.
Liquids also can cause gradual corrosion of power cord terminals and/or the
connector terminals on a power adapter, which can eventually result in
overheating.
Always connect power cords and signal cables in the correct order and ensure
that all power cord connectors are securely and completely plugged into
receptacles.
