hazardous voltages, disconnect all power cords.
•Connect all power cords to a properly wired and grounded electrical
outlet. Ensure that the outlet supplies proper voltage and phase rotation
according to the system rating plate.
•Connect any equipment that will be attached to this product to properly
wired outlets.
•When possible, use one hand only to connect or disconnect signal cables.
•Never turn on any equipment when there is evidence of fire, water, or
structural damage.
•Disconnect the attached power cords, telecommunications systems,
networks, and modems before you open the device covers, unless
instructed otherwise in the installation and configuration procedures.
•Connect and disconnect cables as described in the following procedures
when installing, moving, or opening covers on this product or attached
devices.
To disconnect:
1. Turn off everything (unless instructed otherwise).
2. Remove the power cords from the outlets.
3. Remove the signal cables from the connectors.
4. Remove all cables from the devices.

CAUTION:
The battery is a lithium ion battery. To avoid possible explosion,
do not burn. Exchange only with the IBM-approved part. Recycle
or discard the battery as instructed by local regulations. In the
United States, IBM has a process for the collection of this battery.
For information, call 1-800-426-4333. Have the IBM part number for
the battery unit available when you call. (C007)
Protecting against Electrostatic Discharge – Static electricity can
harm delicate components inside your computer. To prevent static
damage, discharge static electricity from your body before you touch any
of your computer’s electronic components, such as the microprocessor.
You can do so by touching an unpainted metal surface, such as the
metal around the card-slot openings at the back of the computer.
As you continue to work inside the computer, periodically touch an
unpainted metal surface to remove any static charge your body may
have accumulated. In addition to the preceding precautions, you can also
take the following steps to prevent damage from electrostatic discharge:
•When unpacking a static-sensitive component from its shipping
carton, do not remove the component from the antistatic packing
material until you are ready to install the component in your
computer. Just before unwrapping the antistatic packaging, be sure
to discharge static electricity from your body.
•When transporting a sensitive component, first place it in an
antistatic container or packaging.
•Handle all sensitive components in a static-safe area. If possible, use
antistatic floor pads and workbench pads.
