4.4.3 Inactive/Cold Replacement Workflow of the PSU
4.4.3 Inactive/Cold Replacement Workflow of the PSU
You can perform inactive/cold replacement of the PSU in the following configuration:
- Building block configuration where two or more physical partitions are operating
Before replacing the PSU, see "Precautions for PSU replacement" in "7.1 Precautions for FRU Replacement."
Table 4-31 shows the workflow for inactive/cold replacement of the PSU.
Work Order | Task | Reference |
---|---|---|
1 | Checking the operating condition of the system | "9.2.1 Checking the Operation Status of Physical Partitions and Logical Domains" |
2 | Confirming the PSU to be replaced | "8.2 Troubleshooting" |
3 | Checking the operation status of the SPARC M12-2S that houses the PSU to be replaced | "Table 2-20 PSU LEDs and Their States" |
4 | Powering off the physical partition containing the SPARC M12-2S that houses the FRU requiring maintenance | "9.5.1 Stopping a Specific Physical Partition" |
5 | Switching the mode switch on the OPNL to Service | "2.3.2 OPNL Control Function" |
6 | Releasing the SPARC M12-2S requiring maintenance from the building block configuration | "9.6.1 Releasing the SPARC M12-2S From the Building Block Configuration" |
7 | Placing the SPARC M12-2S requiring maintenance into the cold state | "9.8.2 Removing the Power Cords" |
8 | Removing the PSU from the SPARC M12-2S | "13.3 Removing a PSU" |
9 | Installing a PSU in the SPARC M12-2S, and placing the SPARC M12-2S that required maintenance into the hot state | "13.4 Installing a PSU" "10.1.1 Installing a Power Cord" |
10 | Incorporating the SPARC M12-2S that required maintenance into the building block configuration | "10.4.1 Incorporating the SPARC M12-2S Into a Building Block Configuration" |
11 | Confirming that there is no problem with the replacement PSU | "10.5.3 Checking the FRU Status After Maintenance" |
12 | Switching the mode switch on the OPNL to Locked, and powering on the physical partition containing the SPARC M12-2S that has undergone maintenance | "10.8 Powering on a Physical Partition" |
