Always observe the following precautions to reduce the risk of injury and property damage.
Do not attempt to service a product yourself unless instructed to do so by the IBM HelpCenter.
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 HelpCenter.
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.
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.
If a receptacle (power outlet) that you intend to use with your computer equipment appears to
be damaged or corroded, do not use the outlet until it is replaced by a qualified electrician.
Do not bend or modify the plug. If the plug is damaged, contact the manufacturer to obtain a
replacement.
Some products are equipped with a three-pronged plug. This plug fits only into a grounded
electrical outlet. This is a safety feature. Do not defeat this safety feature by trying to insert it
into a non-grounded outlet. If you cannot insert the plug into the outlet, contact an electrician
for an approved outlet adapter or to replace the outlet with one that enables this safety feature.
Never overload an electrical outlet. The overall system load should not exceed 80 percent of
the branch circuit rating. Consult an electrician for more information if you have questions
about power loads and branch circuit ratings.
Be sure that the power outlet you are using is properly wired, easily accessible, and located
close to the equipment. Do not fully extend power cords in a way that will stress the cords.
Connect and disconnect the equipment from the electrical outlet carefully
