Use this procedure to replace the cache battery pack on
a battery card.
Identify the system that you will be working on by using
the identify the system process to turn on the system locate (blue)
indicator. For more information, see Control panel

Attention: Before continuing
with this procedures, determine that it is safe to replace the cache
battery pack. See

Attention: To maintain system
availability and prevent possible data loss, it is important to understand
that these features have implications on the serial-attached SCSI
(SAS) configuration and data accessibility of the system. Review the
SAS
subsystem topic to understand the various
SAS configuration and service considerations.
Before servicing or installing any features,
review the I/O configurations for each logical partition on your system.
It is important to understand the differences between the various
configurations and the resulting service considerations. In addition,
consider possible impacts to the following areas:
- Logical partitions and their I/O adapter assignments
- RAID array configurations
- Physical disk locations
- Path to your boot device
Complete the following steps to replace a nonconcurrent
maintainable battery pack:
- Remove the controller from the system. For
more information, see Removing
the 8202-E4B, 8202-E4C, 8202-E4D, 8205-E6B, 8205-E6C,
or 8205-E6D RAID/cache
storage controller.
- Place the controller on a surface that is electrostatic-discharge
protected.
- Unplug the battery connector (A) from
its connector on the adapter, squeezing the retaining latch while
gently pulling on the plug. The plug connects to the board
in only one way; therefore, it cannot be inserted incorrectly during
the replacement procedure.
Note: Ensure that the cache battery pack
is disconnected for at least 60 seconds before connecting the new
battery. This is the minimum amount of time needed for the adapter
to recognize that the battery has been replaced.

- Remove the battery assembly:
- Remove the mounting plate from the standoffs, one standoff at
a time
- Push in the standoff retaining tab and pull up on the mounting
tab until the standoff is released through the hole in the mounting
tab. Repeat this step for the second standoff.
Note: - The battery is mounted on a black plastic plate with two tabs,
secured by white plastic standoffs with the retaining tabs.
- If the retaining tab is difficult to push in, turn the white standoff
so its retaining tab faces away from the battery pack.
- Install the battery on to the posts until the
latches click into place.

- Reinsert the pins into the rivets from the
rear of the adapter.
- Connect the cache battery pack connector (B) to
the adapter. The plug connects to the adapter in only one
way; therefore it cannot be inserted incorrectly.
- Reinstall the adapter and restart the cache. For
