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

, 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.

Do not use any power adapter that shows corrosion at the ac input pins or

shows signs of overheating (such as deformed plastic) at the ac input or

anywhere on the power adapter.

Do not use any power cords where the electrical contacts on either end show

signs of corrosion or overheating or where the power cord appears to have

been damaged in any way.
