Solution

DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE FIELD ENGINEER/ADMINISTRATOR NEED?:
Sun Fire X4500 Training

TIME ESTIMATE: 60 minutes

TASK COMPLEXITY: 3

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW: A Sun Fire X4500 CPU Module 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:

To replace the CPU:

1. Power off the server.

2. Remove the cable management arm.

See one of the following depending on your system:


Sun Fire X4500/X4540 Installation Guide
Sun X4500-J Slide Rail Installation Guide (X4500)
Early-Production Slide Rail and CMA Information (X4500)
3. Remove the system controller.

The CPUs are located inside the system controller.

4. Identify which CPU module you are replacing, either CPU 0 or CPU 1.

The CPUs are labeled.

5. Remove heatsink assembles by undoing the two screws a half to a full turn each alternately. Remove the CPU by pulling the socket release lever out and up.

6. Use the included alcohol pad to remove all thermal grease from the bottom of the heat sink.

7. Inspect the heat sink for dust and lint. Clean if necessary.

8. Unpack the new CPU.

9. Install the new CPU, or reinstall the existing CPU.

10. Align the CPU to the socket.

a. Gently insert the CPU pins into the socket.

11. When the CPU is fully seated in the socket, pivot the release lever down until it is locked into position, at the side of the socket, then apply the thermal grease to the top of the replaced CPU in the required pattern.

12. Ensure that the foam strip under the heat sink area is intact and that it has not been removed, loosened, or damaged. This foam strip is critical to proper air flow.

13. Carefully position the heat sink onto the CPU, aligning it with the mounting posts to reduce movement after it makes initial contact with the layer of thermal grease.

14.Reinstall the heat sink by using a No. 2 Phillips screwdriver to secure the two screws.

a. Tighten one screw two to three turns and then tighten the other screw two to three turns.

b. Alternate between the two screws until they are firmly attached.

15. Return the system controller cover and tighten the three captive screws.

16. Replace the cable management arms and return the system controller to the server.

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

PARTS NOTE: N/A
