Replacing the system processor module in the 5148-21L, 5148-22L, 8247-21L, 8247-22L, 8284-21A, or 8284-22A

Learn how to replace the system processor module.

1. Ensure that you have the electrostatic discharge (ESD) wrist strap on and that the ESD clip is connected to an unpainted metal surface. If not, do so now.
2. Prepare the system processor module for installation:
   1. Remove the replacement processor module from the shipping tray. Using the supplied removal tool, align the beveled corner (A) of the tool over the beveled corner of the module, as shown in Figure 1.
   2. Lower the tool over the system processor module by ensuring that the two guide pins (C) are inserted into the alignment holes (B) on each side of the tool, as shown in Figure 1. Then, push down on the tool to lock the system processor module into the tool, as shown in Figure 2. Do not press the blue release tabs until directed to do so later.

3. Prepare for system processor module installation:
   1. Grasping the sides of the tool and system processor module, carefully lift it slightly out of the system processor module tray. Then, turn it over so that the system processor module side is up.
   2. Ensure that both jaws (A) are firmly grabbing the system processor module, as shown in Figure 3.
      Note: If both jaws are not firmly grabbing the system processor module, press down on the corner of the system processor module closest to the jaw until it locks into place. Do not touch any part of the system processor module other than the corners.

4. Install the system processor module:
   1. If dust or debris is present on the system processor socket, use the supplied air pump (part number 45D2645) to clean the socket. Blow small bursts of air from the center toward the sides of the socket, as shown Figure 4.
      Figure 4. Removing dust and debris from the system processor socket

      
   2. Lower the tool and system processor module onto the socket. Align the beveled corner (A) of the tool with the beveled corner on the socket. Ensure that the two guide pins (C) are inserted into the alignment holes (B) on each side of the tool. Use care to lower the tool evenly without tilting the tool. See Figure 5.
      Note: Do not attempt to slide the tool and the system processor module in any direction while the system processor module is touching the socket. If the tool and the system processor module are not aligned with the guide pins, lift the tool and the system processor module and reposition them.
      Figure 5. Installing the system processor module

      
   3. After the tool and system processor module holes and guide pins are properly aligned, squeeze and hold the two blue release tabs (A) together until a firm stop is reached, as shown in Figure 6. Then, lift the tool off the system processor module.

5. Inspect the thermal interface material (TIM) for visible signs of damage, as shown in Figure 7.
   Note: When the heat sink is removed from the failed system processor module, the TIM should be adhered to the heat sink. Unless damaged, the TIM that is adhered to the heat sink can be reused. Replacing the TIM is optional and is only performed if the TIM is damaged. Do not reuse the removed heat sink if the TIM is damaged. Either discard the heat sink and the damaged TIM locally or return them to IBM based on part order form part status. It is recommended that a spare TIM and heat sink, (part number 00FV742), be on hand when replacing the system processor module.

6. Are you replacing the TIM or heat sink?

   Yes:

   Continue with step 7.

   No:

   Go to step 8.

7. Install a new TIM pad:
   1. If the TIM or heat sink must be replaced, order TIM and heat sink (part number 00FV742).
   2. Open the TIM packaging and carefully remove the TIM, holding it by the edges of the carrier strip and holding it away from the shipping container.
   3. Remove the protective film from the clear carrier strip by using the supplied tweezers.
      Note: The TIM must remain flat. Small wrinkles are acceptable, but folds are not acceptable.
   4. Using the tweezers, remove the TIM from the carrier strip and center it onto the system processor module with the black side facing up. If the replacement TIM has a red stripe, the side with the red stripe must be facing up. Align the beveled edges of the TIM and the system processor module (A), as shown in Figure 8.
      Figure 8. Installing the TIM onto the processor lid

      
8. Install the heat sink:
   1. Lower the heat sink over the system processor module, ensuring that the two guide pins (B) are inserted into the alignment holes on each side of the tool, as shown in Figure 9.
   2. Ensure that the heat sink load arm is engaged.
      Note: If the load arm is not engaged, you must manually engage the load arm onto the heat sink while the load screw is being tightened. See Figure 10.
      Figure 9. Installing the heat sink

      
9. Secure the heat sink:
   1. Upon placing the heat sink on the system processor module, ensure that the heat sink load arm on the side of the heat sink becomes engaged, as shown in Figure 10.
   2. While you are holding the heat sink in place, use the supplied 5.5 mm nut driver (part number 43W3032) to tighten the heat sink actuation screw. Turn the screw clockwise a few turns.
   3. Is the load arm still engaged?

      Yes:

      Continue turning the actuation screw clockwise until a firm stop is reached. If a torque tool is available, tighten the screw to 2.0 nm.

      No:

      Unscrew the actuation screw. Hold the load arm onto the heat sink while you are tightening the screw until a firm stop is reached. If a torque tool is available, tighten the screw to 2.0 nm.

      Note: If during this step, the heat sink moves noticeably, it is likely that the load arm is not engaged. If the heat sink moves noticeably, unscrew the actuation screw and hold the load arm onto the heat sink while you are tightening the screw until a firm stop is reached. If a torque tool is available, tighten the screw to 2.0 nm.

10. Replace the air baffle by lowering it into position as shown in Figure 11.

11. Lightly grip the system processor module that you replaced by the edges and lift it off of the packaging cover. Align the beveled corner of the module (A) to the corner of the packaging with triangle (B) and place it in the packaging, as shown in Figure 12. Close the packaging cover.
