How to Replace a Sun Fire X2270 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:

Removing the CPU and Heatsink

1. Power off the system and remove the cover.
2. Remove the air duct as described in Replacing the Air Duct.
3. Remove the four screws securing the heatsink to the board.

Caution - The heatsink can become extremely hot. Be sure it has had sufficient time to cool before handling.

4. Twist the heatsink slightly to the right or left to break the seal with the thermal grease.
5. Lift the heatsink away from the CPU.
6. Place the heatsink upside-down on a flat surface to prevent the thermal grease from contaminating other components.
7. Pull the socket release lever up to the fully open, perpendicular position.
8. Open the CPU cover.
9. Lift the CPU out of the socket, leaving the release lever in the open position.

Installing a Replacement CPU

Follow these steps to install a CPU and heatsink if you are replacing a CPU. If you want to install a new CPU or install a second CPU into a formerly single-CPU system, see Installing a New CPU.

Caution - Observe the appropriate ESD precautions in ESD Precautions when handling the CPU.

1. Unpack the new CPU.
2. Ensure that the socket release lever is in the fully open, perpendicular position and the CPU cover is open.
3. Align the small triangle on the upper-left corner of the CPU with the alignment triangle on the motherboard. In addition, ensure that the alignment post on the socket engages the semi-circular cutout on the CPU.
4. Insert the CPU into the socket.

Caution - If the CPU is correctly aligned, you should be able to easily insert the CPU into the socket. If you feel more than minimal resistance, stop and recheck the alignment. Forcing a misaligned CPU into the socket can permanently damage the device.

5. When the CPU is fully seated in the socket, close the CPU cover.

Note - The CPU cover might not align correctly with the chip after it is installed. If this happens, open the cover and push the cover slightly to the side to better align it with the chip, then reclose the cover.

6. Rotate the socket release lever down until it snaps into place, securing the CPU in the socket.
7. Use the entire syringe contents to apply thermal grease in a star pattern to the top of the CPU.

Note - If you are replacing an existing heatsink with a new heatsink, you do not need to use the syringe to add additional thermal grease to the heatsink, as new heatsinks are pre-greased.

8. Gently distribute the thermal grease and remove any excess so that only an extremely thin, uniform layer remains. If any voids or crevices appear that could lead to air pockets, reapply the grease until you achieve a thin but compact consistency.
9. Use an alcohol pad to remove all thermal grease from the bottom of the previously used heatsink.
10. Inspect the heatsink for dust and lint. Clean if necessary.
11. Carefully position the heatsink on the CPU, aligning it with the mounting posts to reduce movement after it makes initial contact with the layer of thermal grease.

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

12. Fasten the four screws attaching the heatsink to the motherboard. Alternate between the four screws, turning each screw two turns until all are securely fastened.
13. Reinstall the air duct and the system cover.

Installing a New CPU

Note - Replacement of a CPU and heatsink should only be done by trained service personnel. If you are replacing an already installed CPU, rather than adding a new one, follow the instructions in Replacing a CPU and Heatsink.

Caution - Observe the appropriate ESD precautions in ESD Precautions when handling the CPU.

1. Unpack the new CPU.
2. If you are installing a second CPU into a formerly single-CPU system, you will need to remove the socket cover before installing the new CPU.
3. Ensure that the socket release lever is in the fully open, perpendicular position and the CPU cover is open (see FIGURE 3-37).
4. Align the small triangle on the upper-left corner of the CPU with the alignment triangle on the motherboard. In addition, ensure that the alignment post on the socket engages the semi-circular cutout on the CPU.
5. Insert the CPU into the socket.

Caution - If the CPU is correctly aligned, you should be able to easily insert the CPU into the socket. If you feel more than minimal resistance, stop and recheck the alignment. Forcing a misaligned CPU into the socket can permanently damage the device.

6. When the CPU is fully seated in the socket, close the CPU cover.

Note - The CPU cover might not align correctly with the chip, after it is installed. If this happens, open the cover and push the cover slightly to the side to better align it with the chip, and reclose the cover.

7. Rotate the socket release lever down until it snaps into place, securing the CPU in the socket.
8. Inspect the heatsink for dust and lint. Clean if necessary.
9. Remove the plastic protective cover from the bottom of the heatsink. The plastic cover protects the grease on the bottom of the heatsink.
10. Carefully position the heatsink on the CPU, aligning it with the mounting posts to reduce movement after it makes initial contact with the layer of thermal grease.

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

11. Fasten the four screws attaching the heatsink to the motherboard. Alternate between the four screws, turning each screw two turns until all are securely fastened. See FIGURE 3-40.
12. Reinstall the air duct and the system cover.
