Important

Gap pad/putty pad replacement guidelines

• To identify the gap pad/putty pad location and orientation, see Gap pad/Putty pad identification and location.

• Before replacing the gap pad/putty pad, gently clean the interface plate or the hardware surface with an alcohol cleaning pad.

• Hold the gap pad/putty pad carefully to avoid deformation. Make sure no screw hole or opening is blocked by the gap pad/putty pad material.

• Do not use expired putty pad. Check the expiry date on putty pad package. If the putty pads are expired, acquire new ones to properly replace them.

Attention

• Read Installation Guidelines and Safety inspection checklist to ensure that you work safely.

• Turn off the corresponding DWC tray that you are going to perform the task on.

• Disconnect all external cables from the enclosure.

• Use extra force to disconnect QSFP cables if they are connected to the solution.

• Each processor socket must always contain a cover. When removing or installing a processor, 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.

• Do not allow the thermal grease on the processor or water loop 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 the cold plate until you are instructed to do so.

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

• To avoid damaging the water loop, always use the water loop carrier when removing, installing or folding the water loop.

Note

• 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.

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

Firmware and driver download: You might need to update the firmware or driver after replacing a component.

• Go to Drivers and Software download website for ThinkSystem SD650-N V3 to see the latest firmware and driver updates for your server.

• Go to Update the firmware for more information on firmware updating tools.

Procedure

1. Follow the following steps if you are replacing processors:
   1. If there is any old thermal grease on the processor and the cold plate, gently clean the top of the processor and the cold plate using an alcohol cleaning pad.
   2. Remove the processor identification label from the water loop and replace it with the new label that comes with the replacement processor. If you are unable to remove the label and place it on the new water loop, or if the label is damaged during transfer, write the processor serial number from the processor identification label on the new water loop in the same location as the label would be placed using a permanent marker.
   3. Apply the thermal grease on the top of the processor with syringe by forming four uniformly spaced dots, while each dot consists of about 0.1 ml of thermal grease
      Note

      Carefully place the processor and retainer on a flat surface with the processor-contact side down.

      Figure 2. Thermal grease application
      
      
2. Install processor retainers onto processor if needed.
   1. Align the triangular mark on the processor retainer with the triangular mark on the processor corner edge.
   2. (Intel® Xeon® CPU Max only) Make sure the slot on the TIM breaking cam is vertical. See Figure 4.
   3. Gently place the processor retainer on the processor; then, carefully press the four sides of the processor retainer to secure the processor.

3. Remove two plastic grease covers if needed.
   1. Use a pair of scissors to cut off the tape.
   2. Remove plastic grease covers from the underside of water loop cold plates.
   Note

   The right node is shown as example. Remove plastic grease covers if needed when installing processor in either node.

   Figure 6. Plastic grease covers removal
   
   
4. Align the triangular marks on the processor retainers with the triangular slots on the underside of the water loop cold plate; then, attach the processors to the underside of the water loop cold plate by inserting the processor retainer posts and clips features into the openings at the four corners of the cold plate.

5. Rotate all anti-tilt wire bails (8x anti-tilt wire bails per node) outwards to the unlocked position.

6. Check the gap pads on the water loop, if any of them are damaged or detached, replace them with the new ones.

Make sure to follow Gap pad/putty pad replacement guidelines.

7. Carefully rotate the top side of the water loop, position the water loop on the two guide pins near the rear of the node; then, gently put the water loop down and ensure it is firmly seated on the system board.

8. Ensure the processors are secured properly.

   1. Rotate 8x anti-tilt wire bails outwards to the locked position.

   2. Fully tighten 8x Torx T30 captive screws on cold plates with a general screwdriver, following the installation sequence shown on the cold plate label.

      Note

      For reference, the torque required for the screws to be fully tightened/removed is 10+/- 2.0 lbf-in, 1.1+/- 0.2 N-m.
      Attention

      To prevent damage to components, make sure that you follow the indicated tightening sequence.

11. Install water loop screws (9x Torx T10 screws per node) with a torque screwdriver set to the proper torque.
    Note

    For reference, the torque required for the screws to be fully tightened/removed is 5.0+/- 0.5 lbf-in, 0.55+/- 0.05 N-M.
