Installing a processor

Hewlett Packard Enterprise recommends identifying the processor and socket components before performing this procedure.

Prerequisites

Before you perform this procedure, make sure that you have the following items available:

  • The components included with the hardware option kit

  • T-20 Torx screwdriver

  • 1.0 gm (0.5 ml) or two 0.5 gm (0.25 ml) of thermal grease

  • Alcohol wipe

Procedure
  1. Observe the following alerts:
    CAUTION: To avoid damage to the processor or system board, only authorized personnel should attempt to replace or install the processor in this server.
    CAUTION: To prevent possible server malfunction and damage to the equipment, multiprocessor configurations must contain processors with the same part number.
    CAUTION: If installing a processor with a faster speed, update the system ROM before installing the processor.

    To download firmware and view installation instructions, see the Hewlett Packard Enterprise Support Center website.

    CAUTION: THE CONTACTS ARE VERY FRAGILE AND EASILY DAMAGED. To avoid damage to the socket or processor, do not touch the contacts.
  2. Power down the server.
  3. Remove all power:
    1. Disconnect each power cord from the power source.
    2. Disconnect each power cord from the server.
  4. Do one of the following:
  5. Remove the access panel.
  6. Do one of the following:
  7. Remove the heatsink blank.
  8. Use a T-20 Torx screwdriver to loosen the three captive screws in the sequence shown in the following image, and then pivot the force frame upward.

    Opening the force frame
  9. Remove the external cap:
    1. Hold the lift tabs near the front end of the rail frame, and then pivot the rail frame to the vertical position.
    2. Slide the external cap out of the rail frame.

      Retain the external cap for future use.


      Removing the external cap from the rail frame
  10. Install the processor:
    1. Hold the processor by its carrier handle and slide the processor into the rail frame until it engages with a click sound.
    2. Remove the pin field cover cap.
      CAUTION:

      To prevent the risk of damaging the pins in the processor socket, do not reinstall the pin field cover cap after removing it.

    3. Hold the lift tabs near the front end of the rail frame, and then pivot the rail frame to the closed position.

      A click sound indicates that the rail frame is properly engaged.


      Installing the processor
  11. Close the force frame:
    CAUTION:

    Do not overtighten the screws as this might damage the system board or the processor socket.

    1. Pivot the spring loaded force frame downward and hold it down (callout 1).
    2. Use a T-20 Torx screwdriver to tighten the captive screws in the sequence shown in the following image (callouts 2–4).

    When using a torque wrench to tighten the screws, apply a torque of 1.58 N⋅m (14 lbf-in).


    Closing the force frame

  12. Remove the thermal interface protective cover from the new heatsink.
  13. Install the heatsink:
    CAUTION:

    To prevent mechanical damage or depositing oil on your hands or other contaminant to the heatsink contact surface, hold the heatsink only by the edge of its base plate. Do not touch the heatsink fins.

    CAUTION:

    To prevent thermal failure or component damage, do not move the heatsink once the bottom of its base plate touches the top of the processor. Excessive heatsink movement can cause the thermal grease to smear and become uneven. Voids in the compound can adversely impact the transfer of heat away from the processor.

    CAUTION:

    Heatsink screws must be tightened and loosened in alternating sequence. Do not overtighten the screws as this might damage the system board or the processor socket.

    1. Position the heatsink on top of the processor, ensuring that it is properly seated before securing the screws.
    2. Use a T-20 Torx screwdriver to tighten the captive screws in the sequence specified on the heatsink label.

      When using a torque wrench to tighten the screws, apply a torque of 1.58 N-m (14 lbf-in).


    Installing the heatsink
  14. Do one of the following:
  15. Install the access panel.
  16. Install the server into the rack.
  17. Connect each power cord to the server.
  18. Connect each power cord to the power source.
  19. Power up the server.

The installation is complete.
