Complete this task to remove the battery backup unit from the server enclosure, 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. You must also ensure that the error indicator is lit on the resource and have a replacement battery backup unit ready for replacement.
Removing and replacing a
battery backup unit might result in the following effects:
- While a battery backup unit is out of the enclosure slot, the enclosure is more susceptible to single point of failure errors.
- Removing a battery backup unit that does not have a lit error indicator results in a processor card failover.
- Removing the battery backup unit might result in loss of access to improperly configured host systems.
- Removing a battery backup unit without immediate replacement by either another battery backup unit or a battery backup unit blank might result in the overheating of the enclosure.
- The storage unit might experience performance degradation while a battery backup unit is missing from its slot.
Important: When removing a battery backup unit from 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 unit is located horizontally in the middle of the expansion enclosure.
These images show a battery backup unit removal procedure.
You must replace the battery backup unit with another battery backup
unit that is in working condition. If you do not have a replacement battery
backup unit, you must place a battery backup unit blank in the empty slot
to prevent overheating. If you do not replace the battery backup unit, or
if you insert a blank unit, the processor card associated with the missing
battery remains offline and your server or expansion unit operates in a mode
that risks data loss in the event of a failure.
