Replacing the rechargeable battery pack
You can replace battery packs that are maintainable both concurrently and nonconcurrently.
The battery pack replacement procedure you follow depends on whether your battery pack is concurrently maintainable or nonconcurrently maintainable.
Note: When replacing the cache battery pack, the battery must be disconnected
for at least 60 seconds before connecting the new battery. This is
the minimum amount of time needed for the card to recognize that the
battery has been replaced.
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.
Attention: Data loss can occur; if the cache battery pack
is not already in the error state, follow the steps described in Forcing a rechargeable battery error before proceeding.
After the battery is in the error state, replace it with a new battery
by completing the appropriate replacement procedure.
Attention:
- Static electricity can damage this device and your system unit.
To avoid damage, keep this device in its anti-static protective bag
until you are ready to install it. To reduce the possibility of electrostatic
discharge, follow the precautions listed below:
- 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 anti-static package, touch it to an unpainted metal part of the system unit for at least two seconds. (This 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.
