4.2.12 Active/Cold Replacement Workflow of the PSUBP


4.2.12 Active/Cold Replacement Workflow of the PSUBP
You can perform active/cold replacement of the PSUBP in the following configuration:
  1. Configuration connecting two or more SPARC M12-2S units to a physical partition
Table 4-19 shows the workflow for active/cold replacement of the PSUBP.

*1 This unit and the XSCFU cannot be replaced at the same time.
*2 If the replaced PSUBP was in a SPARC M12-2S with no PCIe cards mounted, no diagnosis is necessary (because diagnosis was performed in the previous step).
