Replacing a battery pack
Follow these guidelines before you replace the battery pack.
Note: When replacing the cache battery pack, the battery must be disconnected
for at least 60 seconds before you connect the new battery. This duration
is the minimum amount of time that is needed for the card to recognize
that the battery has been replaced.
Note: 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.
Attention: To prevent data loss, if the cache battery
pack is not already in the error state, follow the steps described
in Forcing a rechargeable battery error before proceeding. If the
cache data present LED is flashing, do not replace the cache battery
pack or data will be lost. See the feature descriptions and the figures
in the following sections to determine if your adapter has a cache
data present LED and the location of the LED.
Attention: Static electricity can
damage this device and your system unit. To avoid damage, keep this
device in its antistatic protective bag until you are ready to install
it. To reduce the possibility of electrostatic discharge, read the
following precautions:
- Limit your movement. Movement can cause static electricity to build up around you.
- Handle the device carefully, holding it by its edges or its frame.
- Do not touch solder joints, pins, or exposed printed circuitry.
- Do not leave the device where others can handle and possibly damage the device.
- While the device is still in its antistatic package, touch it to an unpainted metal part of the system unit for at least 2 seconds. (This duration drains static electricity from the package and from your body.)
- Remove the device from its package and install it directly into your system unit without setting it down. If it is necessary to set the device down, place it on its static-protective package. (If your device is a controller, place it component-side up.) Do not place the device on your system unit cover or on a metal table.
- Take additional care when handling devices during cold weather, as heating reduces indoor humidity and increases static electricity.
