Install the water loop

Use this information to install the water loop.

Complete the following steps to install the water loop.

1. Install the water loop.
   1. Orient the water loop with the quick connect facing up that correlates to side of water loop you are installing first.
   2. While holding the water loop with both hands, angle rear downward and insert the quick connect tip through the opening in the rear of the tray.
   3. Orient the water loop with two M.2 backplane guide pins.
   4. Gently put the water loop down and ensure it is seated firmly on the system board.

3. Install the other side of the water loop.
   1. Carefully lift top side of the water loop and rotate it to the other half of the tray.
   2. Carefully insert the quick connect into the tray opening as shown.
   3. Lower and orient the water loop carrier over the M.2 backplane guide pins; then, ensure the processor socket guide pins fit correctly through holes in the water loop cold plates.
   4. Gently lower the water loop down and ensure it is seated firmly on the system board.

4. Make sure quick connects are seated correctly over the four threaded pins for each node.
5. Secure the entire water loop and both quick connects to the tray by carefully inserting and tightening 30 silver Torx T10 screws.
   Note

   The following illustration shows screw locations for one node. The screw locations are identical for two nodes.

6. Loosen water loop carrier screws (20x P2 screws).
   Note

   The following illustration shows screw locations for one node. The screw locations are identical for two nodes.

8. Fully tighten all Torx T30 captive fasteners (entire water loop has 16 total Torx T30 captive fasteners) on cold plates in the installation sequence shown on the cold plate label.
   Attention

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