Removing the system processor module from the 5148-21L, 5148-22L, 8247-21L, 8247-22L, 8284-21A, or 8284-22A

Learn how to remove 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. Open the packaging of the new system processor module, and place the cover upside down next to the tray, as shown in Figure 1. The cover is used for the system processor module that you are replacing.

3. Remove the air baffle by grasping the baffle and lifting it out of the system as shown in Figure 2.

4. Remove the heat sink.
   1. Loosen the heat sink actuation screw by turning the supplied 5.5 mm nut driver (part number 43W3032) counterclockwise (A) until the screw becomes loose and moves freely as shown in Figure 3.
   2. Grip the heat sink (B) by the grooves on opposing sides and remove it by lifting straight up.
   3. Inspect the heat sink for any dust or debris on it. If you must remove dust or debris from the heat sink, it must be done in another room or greater than 25 feet (7.62 meters) away from work area.
   4. Place the heat sink upside down on an Electrostatic Discharge (ESD) surface.

5. Remove dust and debris from the system processor module area.
   1. If dust or debris is present, use the supplied air pump (part number 45D2645) to clean the system processor module area. If your air pump is not assembled as shown in Figure 4, fasten the tip onto the bulb. Blow small bursts of air from the center toward the sides of the system processor module as shown in Figure 4.

6. Prepare the system processor module for removal.
   1. Using the supplied removal tool, align the beveled corner (A) of the tool over the beveled corner of the system processor module as shown in Figure 5.
   2. Lower the tool over the system processor module by ensuring the two guide pins (C) are inserted into the alignment holes (B) on each side of the tool.
      Figure 5. Lowering the removal tool onto the system processor module

      
   3. With the removal tool (A) sitting on top of the system processor module, push down on the tool to lock the system processor module into the tool, as shown in Figure 6. Make sure that both of the tool jaws are locked on the system processor module. Do not press the blue release tabs until directed to do so later.
      Note: The tool drops slightly when you push down so that the jaws can grab the bottom of the system processor module.

7. Holding the outside of the tool, lift the tool and system processor module from the socket. Place them at an angle in the top cover of the system processor module packaging, as shown in Figure 7.
   Note: Setting the tool and system processor module at an angle on the top cover of the system processor module packaging will make it easier to pick up and place in the packaging after you replace the system processor module.

8. Squeeze the two blue tabs to release the system processor module from the tool. See Figure 8.
   Note: To prevent the system processor module from falling, do not squeeze the two tabs before you place the tool on the top cover of the system processor module packaging.
