Install a processor and heat sink

This task has instructions for installing an assembled processor and heat sink, known as a processor-heat-sink module (PHM), a processor, and a heat sink. All of these tasks require a Torx T30 driver.

  • Each processor socket must always contain a cover or a PHM. When removing or installing a PHM, protect empty processor sockets with a cover.

  • Do not touch the processor socket or processor contacts. Processor-socket contacts are very fragile and easily damaged. Contaminants on the processor contacts, such as oil from your skin, can cause connection failures.

  • Remove and install only one PHM at a time. If the system board supports multiple processors, install the PHMs starting with the first processor socket.

  • Do not allow the thermal grease on the processor or heat sink to come in contact with anything. Contact with any surface can compromise the thermal grease, rendering it ineffective. Thermal grease can damage components, such as electrical connectors in the processor socket. Do not remove the grease cover from a heat sink until you are instructed to do so.

  • Thermal grease can stay functional on the heat sink for two years. When installing a new heat sink, make sure to check the manufacturing date to ensure the thermal grease is still functioning. If the date is over two years ago, replace the thermal grease to avoid seating issues.
  • PHMs are keyed for the socket where they can be installed and for their orientation in the socket.

  • See Lenovo ServerProven website for a list of processors supported for your system. All processors on the system board must have the same speed, number of cores, and frequency.

  • Before you install a new PHM or replacement processor, update your system firmware to the latest level. See Update the firmware.

  • Installing an additional PHM can change the memory requirements for your system. See Install a memory module for a list of processor-to-memory relationships.

  • Optional devices available for your system might have specific processor requirements. See the documentation that comes with the optional device for information.

  • The following types of heat sinks are applicable to SD530:

    • Low voltage configuration

      • 108x108x24.5mm heat sink is only applicable to processor socket 1.

      • 85x108x24.5mm heat sink is only applicable to processor socket 2.

    • High voltage configuration

      • T-shaped heat sink is only applicable to processor socket 1.

      • 105x108x24.5mm heat sink is only applicable to processor socket 2.

Before you install a PHM:
The heat sink, processor, and processor retainer for your system might look slightly different from those shown in the illustrations.
  1. Read the following section(s) to ensure that you work safely.
  2. Turn off the corresponding compute node that you are going to perform the task on.

  3. Remove the compute node or compute-expansion node assembly from the chassis (see Remove a compute node from the enclosure or Remove the compute-expansion node assembly from the enclosure).
  4. Remove the compute node cover or disengage the PCIe expansion node (see Remove the compute node cover or Disengage the PCIe expansion node from a compute node).
  5. Remove the air baffle (see Remove the air baffle).
  6. Remove the existing PHM, if one is installed. See Remove a processor and heat sink.

    Replacement processors come with both rectangular and square processor retainers. A rectangular retainer comes attached to the processor. The square retainer can be discarded.
  7. If you are replacing a heat sink, remove the processor identification label from the old heat sink and place it on the new heat sink in the same location. The label is on the side of the heat sink closest to the triangular alignment mark.

    If you are unable to remove the label and place it on the new heat sink, or if the label is damaged during transfer, write the processor serial number from the processor identification label on the new heat sink in the same location as the label would be placed using a permanent marker.

  1. Remove the processor socket cover, if one is installed on the processor socket, by placing your fingers in the half-circles at each end of the cover and lifting it from the system board.
  2. If the processor comes with a T-shaped hear sink, secure the heat sink with two screws on the sides of the node.
    Figure 2. Securing the T-shaped heat sink with two screws

    Use Phillips #1 driver on these two screws.
  3. Install the processor-heat-sink module on the system board.

    PHM installation
    1. Align the triangular marks and guide pins on the processor socket with the PHM; then, insert the PHM into the processor socket.
      To prevent damage to components, make sure that you follow the indicated tightening sequence.
    2. Fully tighten the Torx T30 captive fasteners in the installation sequence shown on the heat-sink label. Tighten the screws until they stop; then, visually inspect to make sure that there is no gap between the screw shoulder beneath the heat sink and the processor socket. (For reference, the torque required for the nuts to fully tighten is 1.4 - 1.6 newton-meters, 12 - 14 inch-pounds).

After you install a PHM:

  1. Reinstall the air baffle (see Install the air baffle).

  2. Reinstall the compute node cover or re-engage the PCIe expansion node (see Install the compute node cover or Re-engage the PCIe expansion node to a compute node).

  3. Reinstall the compute node or the compute-expansion node assembly (see Install a compute node in the enclosure or Install the compute-expansion node assembly into the enclosure).

  4. Check the power LED to make sure it transitions between fast blink and slow blink to indicate the node is ready to be powered on.

  5. Power on the node.

    Check the power LED to make sure it transitions between fast blink and slow blink to indicate the node is ready to be powered on.
