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:
v Limit your movement. Movement can cause static electricity to build up around you.
v Handle the device carefully, holding it by its edges or its frame.
v Do not touch solder joints, pins, or exposed printed circuitry.
v Do not leave the device where others can handle and possibly damage the device.
v 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.)
v 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.
v Take additional care when handling devices during cold weather, as heating reduces indoor humidity
and increases static electricity.
Maintaining the rechargeable battery on the 57B7, 57CF, 574E, and 572F/575C SAS
adapters
Learn about the rechargeable battery maintenance tasks that include displaying rechargeable battery
information, forcing a rechargeable battery error, and replacing the rechargeable cache battery pack.
Attention: Use these procedures only if directed from an isolation procedure or a maintenance analysis
procedure (MAP).
The following list provides references to information about maintaining the rechargeable battery on the
SAS adapters for systems or logical partition that run on the AIX
®
, IBM i, or Linux operating systems:
v For information about maintaining the rechargeable battery for systems that run on the AIX operating
system, see Maintaining the rechargeable battery on the 57B7, 57CF, 574E, and 572F/575C SAS
adapters.
v For information about maintaining the rechargeable battery for systems that run on the Linux
operating system, see Rechargeable battery maintenance.
v For information about maintaining the rechargeable battery for systems that run on the IBM i operating
system, see Rechargeable battery maintenance.
Replacing a 572B nonconcurrent maintainable battery pack
Use this procedure to replace the nonconcurrent maintainable battery pack on adapter type CCIN 572B.
Attention: Before continuing with this procedure, determine that it is safe to replace the cache battery
pack. See Displaying rechargeable battery information. It is safe to replace the cache battery pack when
Yes is displayed next to Battery pack can be safely replaced.
To replace a nonconcurrent maintainable battery pack, complete the following steps:
1. Remove the controller from the system. See your system documentation for instructions.
2. Place the controller on a surface that is electrostatic-discharge protected.
3. Unplug the battery connector (B) 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, so 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 duration is the minimum amount of time needed for the adapter to recognize that
the battery has been replaced.
