Remove a Processor

---

Caution - Processor(s) should be removed only by an Oracle qualified service technician.

---

---

Caution - The processor socket used in the Oracle ZFS Storage ZS3-ES is the Intel LGA2011. Processor removal and replacement must be done using the green color-coded tool (see Removing a Processor). Using a tool with a different color code might result in damage to the processor and the socket. The supported replacement processor for the server includes the correct tool.

1. Use the BUI to identify the faulty processor.

   Go to Maintenance > Hardware, click the Show Details link for the server, click the CPU submenu, and look for a processor with an amber icon to the left of its ID. Click on the row with the failed processor to physically locate it in the server image.

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

      See Powering Down the Server

   2. Extend the server to the maintenance position.

      See Extend the Server to the Maintenance Position.

   3. Attach an antistatic wrist strap.

      See Take Antistatic Measures.

   4. Remove the server top cover.

      Remove the Server Top Cover.

3. To identify the location of the faulty processor, press the Fault Remind button on the motherboard.

   ---

   Note - When the Fault Remind button is pressed, a 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 set 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.

   ---

4. Identify the faulty processor using the fault LED.

   The processor fault LEDs are located next to the processor(s).

   • If processor fault LED is off: processor is operating properly.

   • If processor fault LED is on (amber): processor is faulty and should be replaced.

     Note - Processor 0 (P0) is on the left side when viewing the server from the front.

5. Gently press down on the top of the heat sink to counteract the pressure of the captive spring-loaded screws that secure the heat sink to the motherboard and loosen the four Phillips captive screws in the heatsink for the faulty processor [1].

   Turn the screws counterclockwise alternately one and one half turns until they are fully removed.

   
   
6. To separate the heat sink from the top of the processor, gently twist the heat sink left and right, while pulling upward, then lift off the heatsink and place it upside down on a flat surface [1].

   A thin layer of thermal grease separates the heat sink and the processor. This grease also acts as an adhesive.

   ---

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

   ---

7. Use an alcohol pad to clean the thermal grease from the underside of the heatsink.

   Be very careful not to get the thermal grease on your fingers.

   ---

   Caution - Failure to clean the heatsink prior to removing the processor could result in the accidental contamination of the processor socket or other components. Also, be careful not to get the grease on your fingers as this could result in contamination of components.

8. Disengage the processor release lever on the right side of the processor socket (viewing the server from the front) by pushing down and moving it to the side away from the processor, and then rotating the lever upward [2].
9. Disengage the processor release lever on the left side of the processor socket (viewing the server from the front) by pushing down and moving it to the side away from the processor, and then rotating the lever upward [2].
10. To lift the pressure frame off of the socket, rotate the processor release lever on the right side of the processor toward the closed position (the pressure frame is lifted up as the release lever is lowered toward the closed position) and carefully swing the pressure frame to the fully open position [3].

    ---

    Caution - Whenever you remove a processor, you should replace it with another processor and reinstall the processor heatsink; otherwise, the server might overheat due to improper airflow. For instructions for installing a processor, see Install a Processor.

11. To remove the processor from the socket, acquire the processor removal/replacement tool and perform the following steps:
    1. Locate the button in the center of the top of the processor removal/replacement tool and press it to the down position [1].
    2. Properly position the tool over the processor socket and lower it into place over the processor socket [2].

       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. Press the release lever on the tool to release the center button and engage the processor [3].

       An audible click indicates that the processor is engaged.

    4. Grasp the tool by its sides and remove it from the server [4].
    5. Turn the tool upside down and verify that it contains the processor [5].
    6. While holding the processor tool up side down, press the center button on the tool to release the processor [5].
    7. Carefully grasp the processor on the front and back edges, lift it out of the tool and place it with its circuit side down (the installed orientation) into an antistatic container [6].
    8. Carefully clean the thermal grease off the top of the processor.
