Precautions for PSUBP Maintenance

Note the following points when replacing the PSUBP.
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 PSUBP 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 the above PSUBP stores device identification information.
Set the system time.

After replacing the PSUBP, you need to set the system time. For details, see "Notes
