Removing the system processor module from the 9043-MRU system

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

Before you begin

As part of the system processor module replacement, the heat sink is removed. Before you begin the removal and replacement procedure, ensure that you have a spare TIM and heat sink available.

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. Open the new system processor module packaging and place the cover upside down next to the tray. The cover is used to temporarily hold the system processor module that you are replacing.

  3. Remove the heat sink from the system processor module.

    CAUTION:
    A hot surface nearby. (L007)
    1. Loosen the heat sink actuation screw by turning the supplied 4 mm T-handle hex key counterclockwise. Loosen the screw until it moves freely.
    2. Grip the heat sink on opposing sides and remove the heat sink by lifting it upward. Set the heat sink aside with the module side facing upward.
      Note: If you plan to remove dust or debris from the heat sink, this operation must be performed in another room that is greater than 7.6 m (24.9 ft) away from the work area.

  4. Using the supplied tweezers, remove the TIM from the top of the system processor module and place it in a clean, dry area.
    Be careful not to damage the TIM as it is light and fragile.

  5. Lower the system processor module removal tool onto the system processor module.
    1. Ensure that the system processor module removal tool is in the open position. The top middle ring must be pushed down and top blue tabs must be turned inward.

    2. The system processor modules have different alignments.
      The two front system processor modules (locations C56 and C61) have the keyed location in the right rear of the socket. The two rear system processor modules (locations C14 and C19) are rotated 180 degrees and have the keyed location in the left front of the socket.

    3. Align the system processor module removal tool over the system processor module.
      Ensure that the tool aligns with the system processor module.
    4. Lower the system processor module removal tool over the system processor module.
      Ensure that key locator is properly oriented over the system processor module. Ensure that the guide pins on the socket insert into the alignment holes on sides of the system processor module removal tool.

    5. With the system processor module removal tool sitting on top of the system processor module, push down on the top ring slightly so that the top blue tabs snap outward and the jaws engage with the notch in the system processor module.
      Make sure that both of the system processor module removal tool jaws are locked onto the system processor module by pushing down on the tool.
      Important: Once locked, do not press the blue release ring until directed to do so later.

  6. Lift the system processor module removal tool and system processor module from the socket.
    Hold the outside of the system processor module removal tool. Lift the tool slowly upwards to ensure that the jaws are fully engaged with the system processor module. Ensure that the system processor module does not disengage and fall back into the socket of the system processor module. If the system processor module falls back into the socket of system processor module, the pins can be damaged.

    Place the system processor module at an angle on the top cover of the packaging. Setting the system processor module removal tool and system processor module at an angle on the top cover of the system processor module packaging makes it easier to place the system processor module in the packaging.

  7. Release the system processor module from the system processor module removal tool.
    Push the top ring of the system processor module removal tool downwards. Press the top ring down while pushing the blue tabs inwards. Ensure that the ring catches the openings on the blue tabs and that the blue tabs are locked in a fixed position. You can now lift the system processor module removal tool up from the system processor module.
