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.
