FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW: A Sun Fire X4450 CPU Heatsink needs replacement

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

Orderly shutdown of applications on server
Full backup is recommended as a precaution
Shutdown of OS and power down of server

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:
Ensure standard ESD procedures are followed

1. Power off the server and unplug (REMOVE) power cords
2. Remove the top cover by pulling the release tabs to release the door and moving the fan door to the open position. Press the top cover release button and slide the cover back to allow you to lift it straight up
3. Identify the CPU to be replaced. Fault LED for each CPU can be found on motherboard. Press the button located at the rear right corner of the motherboard to indicate the faulty CPU. (CPU 0 is closest to the PSU bay & CPU 3 is furthest from the PSU bay).
NOTE: CPU Fault LEDs (and DIMM Fault LEDs) operate on stored power for upto a minute when the system is powered down, even after the AC power is disconnected. The stored power lasts for approximately 30 minutes.
4. Remove the memory tray by pressing the tabs away from the memory tray to unlock.
5. Remove the heatsink for faulty CPU by slightly twisting to break grease seal and lift up. Place heatsink upside down on clean area
6. Pull CPU lever slightly down and away from socket and then pull up from horizontal to vertical position
7. Remove the CPU module from the socket
8. Use alcohol pad to clean old thermal grease from the heatsink and old CPU
9. Align and insert new CPU module (ensuring notches match up for correct orientation) and close the lever down into the catch
10. Use one syringe of thermal grease and apply onto CPU in 3 lines (star shape - 2 diagonal lines and one horizontal). Smooth over a thin even layer
11. Align heatsink over CPU ensuring the screws line up with mounting studs
12. Tighten screws 1/2 turn and alternating in an X pattern between screws until fully seated
13. Re-install memory tray
14. Re-install the top cover
15. Re-connect power cords

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:
Login into SP and validate CPUs are seen or via IPMItool
Bring up system and check all CPUs are visible
