Install a Processor

---

Caution - Processors should be installed only by an Oracle qualified service technician.

---

---

Caution - Processor removal and replacement must be done using the correct removal/replacement tool; otherwise, damage might result to the processor or the processor socket. For information on how to select the correct removal/replacement tool, see Selecting the Correct Processor Removal/Replacement Tool.

---

---

Caution - Be careful not to touch the processor socket pins. The processor socket pins are very fragile. A light touch can bend the processor socket pins and damage the board beyond repair. Always use the processor removal/replacement tool to remove and replace the processor.

---

1. Attach an antistatic wrist strap to your wrist, and then to a metal area on the chassis.

   See Take Antistatic Measures.

2. Unpack the replacement processor and place it on an antistatic mat.
3. Ensure that the replacement processor is identical to the processor that was removed.

   For a description of the processors supported by the server, see the Installation , Server Components.

4. Ensure that the two processor ILM assembly levers and the ILM assembly load plate are in the fully open position.

   For instructions for opening the processor ILM assembly levers and the load plate, see Step 6 through Step 8 of Remove a Processor.

5. To install the replacement processor into the processor removal/replacement tool, acquire the correct removal/replacement tool and perform the following steps:

   ---

   Caution - Before installing the processor, ensure that you are using the correct color-coded processor removal/replacement tool. For information on how to select the correct processor removal/replacement tool, see Selecting the Correct Processor Removal/Replacement Tool.

   ---

   1. Press the button in the center of the tool to the down position (see Installing a Processor [1]).
   2. Turn the tool upside down, grasp the processor by its front an back edges and position the processor (circuit side up) in the tool so that the triangle on the corner of the processor aligns with the triangle on the side of the processor removal/replacement tool [2].
   3. Lower the processor into the tool and press the tool release lever to release the center button and engage the processor [3].

      An audible click indicates that the processor is locked in place.

   4. Properly position the tool over the processor socket and lower it into place [4].

      To properly position the tool in the processor socket, rotate the tool until the green or pink triangle (depending on which color-coded tool is being used) on the side of the tool is facing the front of the server and it is over the left side of the processor socket (when viewing the server from the front) and lower the tool into the processor socket.

   5. Press the center button in the tool down to release the processor so that it is installed in the socket [5].
   6. Remove the processor removal/replacement tool [6].

      ---

      Caution - The following figure shows the green color-coded processor removal/replacement tool. If you are installing a 12-core processor, you must use the pink color-coded processor removal/replacement tool; otherwise, damage might result to the processor or the processor socket. For information on how to select the correct processor removal/replacement tool, see Selecting the Correct Processor Removal/Replacement Tool.

6. Visually check the alignment of the processor in the socket.

   When properly aligned, the processor sits flat in the processor socket.

   ---

   Caution - Do not press down on the processor. Irreparable damage to the processor or motherboard might occur from excessive downward pressure. Do not forcibly seat the processor into the socket. Excessive downward pressure might damage the socket pins.

   ---

7. Swing the processor ILM assembly load plate into the closed position [1].

   Ensure that the load plate sits flat around the periphery of the processor.

   
   
8. Engage the processor ILM assembly load lever on the left side of the socket (viewing the server from the front) by rotating it downward and slipping it under the catch [2].
9. Engage the processor ILM assembly hinge lever on the right side of the socket (viewing the server from the front) by rotating it downward and slipping it under the catch [2].
10. Use the syringe (supplied with the new or replacement processor) to apply approximately 0.1 ml of thermal grease to the center of the top of the processor.

    To measure 0.1 ml of thermal grease, use the graduated scale on the thermal grease syringe.

    ---

    Note - Do not distribute the grease; the pressure of the heatsink will do so for you when you install it.

    ---

11. Inspect the heatsink for dust and lint.

    Clean the heatsink if necessary.

12. Orient the heatsink so that the screws line up with the mounting posts [3].

    ---

    Note - The processor heatsink is not symmetrical.

    ---

13. Carefully position the heatsink on the processor, aligning it with the mounting posts to reduce movement after it makes initial contact with the layer of thermal grease [3].

    ---

    Caution - Avoid moving the heatsink after it has contacted the top of the processor. Too much movement could disturb the layer of thermal grease, causing voids, and leading to ineffective heat dissipation and component damage.

14. Tighten the four Phillips screws with a No. 2 Phillips screwdriver alternately one-half turn until fully seated.
15. Return the server to operation.
    1. Install the server top cover.

       See Install the Server Top Cover.

    2. Close the server fan door.
    3. Return the server to the normal rack position.

       See Return the Server to the Normal Rack Position.

    4. Reconnect the data cables and reconnect the power cords to the server power supplies.

       See Reconnect Data Cables and Power Cords.

    5. Power on the server.

       See Power On the Server.

       Verify that the Power/OK status indicator is steady on.

16. Use Oracle ILOM to clear server processor faults.

    Refer to the Oracle Integrated Lights Out Manager (ILOM) 3.1 Documentation Library for more information about the following steps.

    1. To show server faults, log in to the server as root using the Oracle ILOM CLI, and type the following command to list all known faults on the server:

       -> show /PS/faultmgmt

       The server lists all known faults, for example:

       -> show /PS/faultmgmt
       Targets:
           0 (/SYS/MB/P0)Properties:
       Commands:
           cd
           show
        

       Alternatively, to list all known faults in the server, log into the Oracle Solaris OS and issue the fmadm faulty command, or log into the Oracle ILOM service processor from the Oracle ILOM Fault Management Shell and issue the fmadm faulty command.

    2. To clear the fault identified in Step 16.a, type the following command:

       -> set /System/MB/P0 clear_fault_action=true

       For example:

       -> set /System/MB/P0 clear_fault_action=true
       Are you sure you want to clear /SYS/MB/P0 9y/n)? y
       Set ‘clear_fault_action' to ‘true'

       Alternatively, to clear all known faults in the server, log into the Oracle Solaris OS and issue the fmadm repair command, or log into the Oracle ILOM service processor from the Oracle ILOM Fault Management Shell and issue the fmadm repair command.
