DISPATCH INSTRUCTIONS
- WHAT SKILLS DOES THE ENGINEER NEED:
Field training in Sun Fire V880/V890 Server

- TIME ESTIMATE: 20 min
- TASK COMPLEXITY: 1

FIELD ENGINEER INSTRUCTIONS:
- PROBLEM OVERVIEW:
Power supply failed

- WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE
RESOLUTION ACTIVITY?:
A data backup is not a prerequisite but is a wise precaution. The customer is not required to perform a system shutdown.

- WHAT ACTION DOES THE ENGINEER NEED TO TAKE:
The Sun Fire V880/V890 server has N+1 power supply redundancy. The system requires 2 power supplies to operate. It contains 3 power supplies each with its own power cord. You can swap any one power supply while the other two are still running. For a non-redundant power supplies configuration, the system should be powered down before replacing the bad power supply.

Note:
Use max post only when searching for IO Controller issues, Fatal Resets, and Unrecoverable Errors(UEs) that Solaris is unable to properly diagnose. If diag-level is set to max at OBP, confirm with customer that if can be moved to the factory default of min.

See: Guidance for POST Diagnostic Level Setting on Sun Fire[TM] 280R, V480, V490, V880, V890 and V880z servers. (Doc ID 1582330.1) for details.

1. Identify the power supply that you want to remove.
2. Release the AC power cord from the strain-relief tie-wrap on the power supply.
3. Unplug the AC power cord from the power supply and the AC power outlet.
4. Loosen the two captive Phillips screws securing the power supply to the system rear panel.
5. Pull the power supply out from its bay and wait for an acknowledgment message on the system console before installing a new supply.
6. Slowly slide the new power supply into its bay until the connectors on the power supply are fully engaged with the connectors on the power distribution board.
7. Tighten the two captive screws that secure the power supply to the chassis.
8. Connect the AC power cord to both the power supply and a dedicated AC power outlet.
9. If you installed this part as a new option while the system was powered off, you need to perform a reconfiguration boot. A reconfiguration boot is required in order for the operating system to recognize the new device.

OBTAIN CUSTOMER ACCEPTANCE
- WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO
AN OPERATIONAL STATE:
If the replacement was a hot swap on a redundant configuration, the system should be operational and need no further work.

If the replacement was in a system with a single power supply, restart software applications per applicable administration guides to resume system operation.
