FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW: A Sun Fire X4170, X4270 CPU needs replacement

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :

If the system is still up and functioning, customer should perform an orderly and graceful shutdown of applications and OS
A data backup is not a pre-requisite but is a wise precaution.

Note: If this server is part of an Exadata, please follow shutdown instructions in Section 1 of DOC ID: 1539451.1

- WHAT ACTION DOES THE ENGINEER NEED TO TAKE:
Follow standard ESD procedures
1. Power off the server and unplug (REMOVE) the power cords from power supplies
2. Remove the top cover
3. Identify the CPU to be removed by pressing the Fault Remind button. Amber LED indicates the CPU needs to be replaced
4. Unscrew the 2 screws from the heatsink of the faulty CPU (Alternate one and a half turns between each screw until fully remove)
5. Gently twist the heatsink to break the grease gel. Lift off the heatsink and place it upside down on a flat surface
6. Use an alcohol pad to clean the thermal grease from the heatsink (bottom) and the CPU (top) (Be careful to not get thermal grease on other components or your fingers)
7. Push the CPU lever down, move it to the side away from the CPU and rotate upwards to disengage
8. Open the pressure frame and remove the faulty CPU
9. Install the replacement CPU by carefully placing in the socket, ensuring the socket alignment tabs are in the correct position
10. Lower the pressure frame
11. Engage the release lever by pushing it down and under the catch
12. Apply thermal grease (0.1m) to the middle of the top of the CPU, using the syringe within the replacement CPU packaging
13. Ensure the heatsink has no dust and line up the screws with the mounting studs. Place the heatsink on the CPU and align with the mounting posts
14. Tighten the screws, alternating one and a half turns between each screw until fully secured
15. Replace the main cover
16. Re-connect the power cords
17. Log into the ILOM Command Line Interface and clear the fault for the faulty CPU
Example: show /SB/faultmgmt (to review faults)
set /SYS/MB/PX clear_fault_action=true (Where X is the CPU number as identified by the show fault string)

OBTAIN CUSTOMER ACCEPTANCE
- WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO
AN OPERATIONAL STATE:
