Complete this task to install or replace the battery backup unit, either when the system is powered off or powered on.

CAUTION:

The battery is a nickel metal hydride 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.

You must wait a minimum of 45 minutes after the initial failure, as recorded in the Log details page, before replacing the battery backup unit.

Important: When replacing a battery backup unit in an enclosure, care should be taken to ensure that all resources from a particular server enclosure or expansion enclosure are reinstalled into the same physical enclosure and in the same location inside that enclosure.

The battery backup units are located horizontally in the middle of the rear of the enclosure.

Grip the battery backup unit with both hands and align the resource with the slot.
Using both hands, push the battery backup unit into the slot until the handle mechanism stops the forward movement.
Push the handle in and to the right until the release button clicks. This inserts the remaining portion of the battery backup unit into the slot.
The battery backup unit automatically resumes its function after the batteries are fully charged.
