(CAxx) Partition firmware progress codes
Partition firmware progress codes offer information about the progress of partition firmware as it is initializing.
In some cases, a server might hang (or stall) at one of these progress codes without displaying an 8-character system reference code (SRC). Only during such a hang condition should you take any service action related to the progress code.
Note: If the control panel displays more than eight characters, use
only the first eight characters to find the error in the list. Characters
that display after the first eight represent a location code that
assists you in diagnosing the problem.
