Replacing the system processor module in the 5105-22E, 9008-22L, 9009-22A, 9009-22G, 9223-22H, or 9223-22S system

To replace a system processor module in the system, complete the steps in this procedure.

1. Ensure that you have the electrostatic discharge (ESD) wrist strap on and that the ESD clip is plugged into a ground jack or connected to an unpainted metal surface. If not, do so now.
2. Prepare the system processor module for installation:
   1. Ensure that the removal tool is in the open position as shown in Figure 1. The middle ring must be pushed down and blue tabs must be turned inward.

      

   2. Lower the tool over the system processor module as shown in Figure 2. Ensure that the beveled edge on the tool aligns with the beveled edge of the system processor module. Ensure that the two guide pins (A) are inserted into the alignment holes (B) on each side of the tool.

      

   3. With the removal tool sitting on top of the system processor module, push down on the ring (A) slightly so that the blue tabs (B) snap outward and the jaws engage with the system processor module (C) as shown in Figure 3.
      Make sure that both of the tool jaws are locked onto the system processor module by pushing down on the tool.

      Important: Do not press the blue release tabs until directed to do so later.

      

3. Install the system processor module:
   1. If dust or debris is present on the system processor socket, use the supplied air pump to clean the socket. Blow small bursts of air from the center toward the sides of the socket, as shown in Figure 4.

      

   2. Hold the sides of the tool with system processor module and carefully lift the tool out of the system processor module tray.
   3. Lower the tool and system processor module onto the socket. Align the beveled corner of the tool with the beveled corner on the socket. Align the guide pins (A) with 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.

      

   4. Open the latches that hold the system processor module in the supplied removal tool (A) as shown in Figure 6. Push down on the ring (B) while pressing in on the tabs (C).

      

   5. Lift the tool off the system processor module.
4. Inspect the thermal interface material (TIM) for visible signs of damage, as shown in Figure 7.

   

5. Choose one of the following repair options:

   Option	Description
   Is the TIM damaged?	It is damaged. continue to step 6 to replace the TIM and install the existing heat sink.
   Is the TIM not damaged?	It is not damaged and can be reused. continue to step 7 to move the TIM and install the existing heat sink.

6. Use this step to install a new TIM and reuse the existing heat sink.
   1. 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.
   2. 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.
   3. Using the tweezers, remove the TIM from the carrier strip and center it onto the system processor module.
      The TIM has no preferred up side. The TIM can be placed on the system processor module and centered as shown in Figure 8.

      

   4. Place the heat sink on the TIM as shown in Figure 9.

      

7. Use this step to reuse the existing undamaged TIM and heat sink.
   1. Using the tweezers, move the old processor's TIM from the clean, dry surface and center it onto the new system processor module.
      The TIM has no preferred up side. The TIM can be placed on the system processor module and centered as shown in Figure 10.

      

   2. Place the heat sink on the TIM as shown in Figure 11.

      

8. Secure the TIM and heat sink to the socket of the system processor module.
   1. Ensure that the heat sink load arms are engaged as shown by (A) in Figure 12.
   2. Tighten the center load screw clockwise by using the supplied hex key as shown by (B) in Figure 12 until a firm stop is reached. If the heat sink moves noticeably, the load arms are not engaged. Unscrew the center load screw and repeat this step again.

      

9. 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 13. Close the packaging cover.
