Chapter 8. Replacing parts
You can remove and replace customer-replaceable units (CRUs) in control
enclosures or expansion enclosures.
Attention: If your system is powered on and performing I/O operations, go to
the management GUI and follow the fix procedures. Performing the replacement
actions without the assistance of the fix procedures can result in loss of data or loss
of access to data.
Even though many of these procedures are hot-swappable, they are intended to be
used only when your system is not up and running and performing I/O
operations. If your system is powered on and performing I/O operations, go to the
management GUI and follow the fix procedures. Performing the replacement
actions without the assistance of the fix procedures can result in loss of data or loss
of access to data.
Each replaceable unit has its own removal procedure. Sometimes you can find that
a step within a procedure might refer you to a different remove and replace
procedure. You might want to complete the new procedure before you continue
with the first procedure that you started.
Remove or replace parts only when you are directed to do so.
Be careful when you are replacing the hardware components that are located in the
back of the system that you do not inadvertently disturb or remove any cables that
you are not instructed to remove.
Preparing to remove and replace parts
