FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:


PROBLEM OVERVIEW: An Oracle Server X5-2L, X6-2L CPU & Heatsink needs replacement


WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :


Caution  -  The correct color-coded processor removal and replacement tool must be used to remove and replace a processor; otherwise, the processor or the processor socket might get damaged. Additionally, do not use a tool that is designed for earlier generations of Intel processors (CPUs). If you use an earlier generation tool, the processor will only be partially held by the tool and it could fall from the tool, which could damage the processor socket. Also 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 beyond repair. Always use the processor removal and replacement tool to remove and replace the processor.

If the system is still up and functioning, the customer should perform an orderly and graceful shutdown of applications and OS. Then power off the server and remove the AC power cords from the system.



A data backup is not a prerequisite but is a wise precaution.


WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

Removing the CPU



1. Prepare the server for service.


    

  1. Power off the server and disconnect the power cords from the power supplies
    2. 

  2. Attach an antistatic wrist strap to your wrist, and then to a metal area on the chassis
    3. 

  3. Extend the server to the maintenance position
    4. 

  4. Remove the server top cover
    5. 

  5. Swivel the air baffle into the upright position to allow access to the processors
    6. 



2.  Identify the location of the faulty processor by pressing the Fault Remind button on the motherboard I/O card   


Note -  When the Fault Remind button is pressed, an LED located next to the Fault Remind button lights green to indicate that there is sufficient voltage present in the fault remind circuit to light any fault LEDs that were lit due to a failure. If this LED fails to light when you press the Fault Remind button, it is likely that the capacitor powering the fault remind circuit has lost its charge. This can happen if the Fault Remind button is pressed for a long time with fault LEDs lit or if power has been removed from the server for more than 15 minutes.


The processor fault LEDs are located next to the processors:


    

  • If the processor fault LED is off, then the processor is operating properly
    • 

  • If the processor fault LED is on (amber), then the processor is faulty and should be replaced
    • 



3. Gently press down on the top of the heatsink to counteract the pressure of the captive spring-loaded screws that secure the heatsink to the motherboard and loosen the four Phillips captive screws in the heatsink using a No. 2 Phillips screwdriver


Turn the screws counterclockwise alternately one and one-half turns until they are fully released


4.  To separate the heatsink from the top of the processor, gently twist the heatsink left and right, while pulling upward, and then lift off the heatsink and place it upside down on a flat surface   


Note -  Do not allow the thermal grease to contaminate the work space or other components


5. Use an alcohol pad to clean the thermal grease from the underside of the heatsink, being careful not to get the thermal grease on your fingers


6. Disengage the processor release lever on the right side of the processor socket (viewing the server from the front) by pushing down on the lever and moving it to the side away from the processor, and then rotating the lever upward


7. Disengage the processor release lever on the left side of the processor socket (viewing the server from the front) by pushing down on the lever and moving it to the side away from the processor, and then rotating the lever upward


8. To lift the Independent Loading Mechanism (ILM) assembly load plate off of the processor socket, rotate the processor release lever on the right side of the processor toward the closed position (the ILM assembly load plate is lifted up as the release lever is lowered toward the closed position) and carefully swing the ILM load plate to the fully open position


9. To remove the processor from the processor socket, acquire the processor removal and replacement tool and perform the following steps:


    

  1. Locate the button in the center of the top of the processor removal tool and press it to the down position
    2. 

  2. Properly position the tool over the processor socket and lower it into place over the processor socket   

    To properly position the tool over the processor socket, rotate the tool until the green triangle 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
    

    3. 

  3. Press the release lever on the processor tool to release the center button and engage the processor, an audible click indicates that the processor is engaged
    4. 

  4. Grasp the tool by the sides and remove it from the server
    5. 

  5. Turn the tool upside down and verify that it contains the processor
    6. 

  6. While holding the processor tool upside down, press the center button on the tool to release the processor
    7. 

  7. Carefully grasp the processor by the front and back edges, lift it out of the tool and place it with the circuit side down (the installed orientation) into an antistatic container 
    8. 

  8. Carefully clean the thermal grease off the top of the processor
    9. 



 


 Installing the CPU


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 beyond repair. Always use the processor removal and replacement tool to remove and replace the processor


1. Unpack the replacement processor, and place it on an antistatic mat


2. Ensure that the replacement processor is identical to the failed processor that was removed


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


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


    

  1. Press the button at the center of the tool to the down position
    2. 

  2. Turn the tool upside down, grasp the processor by its front and 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 and replacement tool
    3. 

  3.  Lower the processor into the tool and press the tool release lever to release the center button and engage the processor, an audible click indicates that the processor is locked into place.
    4. 

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

    To properly position the tool in the processor socket, rotate the tool until the green triangle 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. 

  5. Press the center button on the tool down to release the processor so that it is installed in the socket
    6. 

  6. Remove the processor removal and replacement tool
    7. 



5. 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.


6. Swing the processor ILM assembly load plate into the closed position, making sure that the load plate sits flat around the periphery of the processor


7. Engage the socket release lever on the left side of the socket (viewing the server from the front) by rotating it downward and slipping it under the catch


8. Engage the socket release lever on the right side of the socket (viewing the server from the front) by rotating it downward and slipping it under the catch


9. 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   


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


10. Inspect the heatsink for dust and lint, clean it if necessary


11. Orient the heatsink so that the screws line up with the mounting posts


12. 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


13. Use a No. 2 Phillips screwdriver to tighten the screws alternately one-half turns until fully seated


14. Return the server to operation:


    

  1. Lower the air baffle to the installed position
    2. 

  2. Install the server top cover
    3. 

  3. Return the server to the normal rack position
    4. 

  4. Reconnect the power cords to the power supplies, and power on the server
    5. 

  5. Use Oracle ILOM to clear server processor faults:
      

    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 system:   

      -> show /SP/faultmgmt
      

      2. 

    2. To clear the fault on processor 0, type the following command as an example:

      -> set /SYS/MB/P0 clear_fault_action=true
      
  
      3. 

    6.
