Replacement Precautions

This section describes the precautions for replacement.
When replacing a FRU, replace it with a part with the same part number or a
succeeding part.
Precautions for MBU replacement
Do not replace the MBU and the PSUBP at the same time. If you replace the MBU
■
and the PSUBP at the same time, the system may fail to operate correctly. Replace
the MBU or PSUBP, execute the showhardconf or showstatus command, and
confirm that the replacement Field Replaceable Unit (FRU) is fully operational.
Then, replace the other FRU.
Do not mount and use any of the following SD cards in the MBU in another
■
chassis:
- the one currently mounted in the SPARC M12-1, or
- one that was once used as a maintenance part
This is because these SD cards store device identification information.
