General safety guidelines
Always observe the following precautions to reduce the risk of injury and property damage.
Service
Do not attempt to service a product yourself unless instructed to do so by the IBM Support
Center. Use only an IBM authorized service provider who is approved to repair your
particular product.
Note: Some parts can be upgraded or replaced by the customer. These parts are referred
to as Customer Replaceable Units, or CRUs. IBM expressly identifies CRUs as such, and
provides documentation with instructions when it is appropriate for customers to replace
those parts. You must closely follow all instructions when performing such replacements.
Always make sure that the power is turned off and that the product is unplugged from
any power source before you attempt the replacement. If you have any questions or
concerns, contact the IBM Support Center.
Power cords and power adapters
Use only the power cords and power adapters supplied by the product manufacturer.
Never wrap a power cord around the 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 the cord and power adapters from liquids. For instance, do not leave your 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 cord or power adapter has been stressed
by misuse. Liquids can also cause gradual corrosion of the power cord terminals and/or
the connector terminals on the 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 and/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.
