Install a processor

This task has instructions for installing a processor. This task requires a Torx T30 driver.

Figure 1. Processor locations

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 approximately 0.65 g of the new thermal grease to the center of the processor top. If you have cleaned the top of the processor with an alcohol cleaning pad, make sure to apply the new thermal grease after the alcohol has fully evaporated.
      Note

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

2. Install processor retainers onto processors if needed.
   1. Align the triangular mark on the processor retainer with the triangular mark on the processor corner edge.
   2. 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. ❶ Use a scissors to cut off tapes.
   2. ❷ Remove plastic grease covers from underside of water loop cold plates.

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 missing, replace them with the new ones.

7. Reinstall the water loop.
   1. ❶ Carefully rotate the top side of the water loop.
   2. ❷ Carefully insert the quick connect into the tray opening as shown.
   3. ❸ Carefully position the water loop on 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. ❶ Rotate anti-tilt wire bails (8x anti-tilt wire bails per node) outwards to the locked position.
   2. ❷ Fully tighten all Torx T30 captive screws (8x Torx T30 captive screws per node) on cold plate with a general screwdriver until they stop, 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 1.1-1.15 newton-meters, 9.8-10.2 inch-pounds.

   Attention

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