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.

Extension cords and related devices

Ensure that extension cords, surge protectors, uninterruptible power supplies, and power strips
that you use are rated to handle the electrical requirements of the product. Never overload
these devices. If power strips are used, the load should not exceed the power strip input rating.
Consult an electrician for more information if you have questions about power loads, power
requirements, and input ratings.
