How to Replace a Sun Fire X2270 M2 CPU & Heatsink.

Solution

DISPATCH INSTRUCTIONS
- WHAT SKILLS DOES THE FIELD ENGINEER/ADMINISTRATOR NEED: No specific skills required

- TIME ESTIMATE: 30 minutes

- TASK COMPLEXITY:0

- FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:
- PROBLEM OVERVIEW: Replace specified faulty CPU and Heatsink
- WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY?:
1. If the operating system (OS) is running, perform a shutdown of the OS, and then press and release the platform Power button on the front panel.
2. Turn off all peripheral devices connected to the system.
3. Disconnect the AC power on the back panel of the server
4. Label and disconnect all peripheral cables and all telecommunication lines connected to I/O connectors or ports on the back panel of the system.
Caution – The system’s printed circuit boards and hard disk drives contain components that are extremely sensitive to static electricity.
5. Before handling components, attach a wrist strap to a chassis ground (any unpainted metal surface).
6. Loosen the captive screw securing the cover to the chassis.
7. Pull the cover slightly toward the back of the server and then straight up to remove it.
8. Lift the cover and remove it.

- WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE:

How to Remove a CPU and Heatsink

1. Prepare the server for service. See the above instructions.
2. Remove the air duct. See How to Remove the Air Duct.
3. Remove the four screws that secure the heatsink to the motherboard.
4. Slightly wiggle the heatsink right and left to break the seal created by the thermal compound.
5. Lift the heatsink away from the CPU and out of the server.
6. Place the heatsink upside down on a flat surface to prevent the thermal compound from contaminating other components or the work space.
7. To open the socket release lever, push the lever down and move it slightly away from the CPU. This action releases the lever from the retaining clip.
8. Lift the lever to its fully-opened position.
9. Lift the CPU cover to its fully-opened position.
10. Remove the CPU, leaving the release lever in the open position.

How to Install a CPU and Heatsink

1. Ensure that the socket release lever and the CPU cover are in their fully-open position.
2. Unpack the new CPU.

Caution - ESD component damage. The CPU is highly sensitive to static electricity. Observe ESD precautions before handling the CPU.
3. Align the small triangle on the upper-left corner of the CPU with the alignment triangle on the socket. In addition, ensure that the alignment post on the socket engages the semicircular cutout on the CPU.
4. Set the CPU in the socket.

Caution - Component and motherboard damage. Do not force the CPU into the socket. The CPU does not need to be pushed downward. When the CPU is correctly aligned, you should be able to easily place the CPU in the socket and it should have minimal movement within the socket. Forcing a misaligned CPU into the socket can permanently damage the component and the motherboard.

5. When the CPU is seated in the socket, close the CPU cover.
6. To secure the CPU in the socket, lower the socket release lever down until it snaps into place under the retaining clip.
7. If you are installing a new heatsink, remove the protective plastic from the base of the heatsink to expose the pre-applied thermal compound and go to Step 10.
8. If you are not installing a new heatsink, use the alcohol pads to remove any residual thermal compound from the bottom of the heatsink.
9. Apply thermal compound to the top of the CPU. For best application, use the entire contents of the pre-filled syringe and apply the compound in a star (asterisk) pattern.
10. Carefully position the heatsink over the CPU, aligning it with the mounting posts. After the heatsink contacts the CPU, minimize the movement.

Caution - If the heatsink is moved too much during its installation, the layer of thermal compound might become uneven, leading to component damage.

11. To secure the heatsink to the motherboard, alternately tighten the four screws. Alternately turn each screw one full turn until all the screws are tightened fully.
12. Install the air duct. See How to Install the Air Duct.
13. Prepare the server for operation. See How to Prepare for Operation.

How to Add a New CPU and Heatsink Assembly

1. Prepare the server for service. See How to Prepare for Service.
2. Remove the air duct. See How to Remove the Air Duct.
3. To unlock the CPU cover, gently push downward on the CPU retaining lever and move it slightly away from the CPU. This action releases the lever from the retaining clip.
4. Lift the lever to its fully open and upright position.
5. Lift the CPU cover to its fully open position.
6. Remove the new CPU from its packaging.

Caution - ESD component damage. The CPU is highly sensitive to static electricity. Observe ESD precautions before handling the CPU.

7. Align the small triangle on the upper-left corner of the CPU with the alignment triangle on the motherboard. In addition, the alignment post on the socket must engage the semicircular cutout on the CPU.
8. Set the CPU in the socket.

Caution - Component and motherboard damage. Do not force the CPU into the socket. The CPU does not require any force and does not need to be pushed downward. When the CPU is correctly aligned, you should be able to easily place the CPU in the socket and it should have minimal movement within the socket. Forcing a misaligned CPU into the socket can permanently damage the component and the motherboard.

9. When the CPU is seated in the socket, close the CPU cover.
10. To secure the CPU in the socket, rotate the socket retaining lever down until it snaps into place under the retaining clip.
11. Remove the protective plastic from the base of the heatsink to expose the pre-applied thermal compound. The plastic cover protects the compound on the bottom of the heatsink. Do not contaminate components or the work space with the thermal compound.
12. Carefully position the heatsink over the CPU, aligning it with the threaded standoffs. After the heatsink contacts the CPU, take care to minimize the movement.

Caution - If the heatsink is moved too much during its installation, the layer of thermal compound might become uneven, leading to component damage.

13. Lower the heatsink onto the CPU.
14. To secure the heatsink, alternately tighten the four screws. Alternately turn each screw one full turn until all the screws are tightened fully.
15. Install the air duct. See How to Install the Air Duct.
16. Prepare the server for operation.
