Replacing parts
You can remove and replace customer-replaceable units (CRUs) in control enclosures or expansion enclosures.
Attention: Even
though many of these components are hot-swappable, they are intended
to be used only when your
system is not
active (no I/O operations). If your system is powered on and processing
I/O operations, go to the management GUI and
follow the fix procedures. Initiating 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.
