Risk of electric shock due to water or a water solution which is present in this product. Avoid working on or near energized equipment with wet hands or when spilled water is present.
Attention

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

  • Ensure proper handling procedures are followed when working with any chemically treated water used in the compute rack cooling system. Ensure that material safety data sheets (MSDS) and safety information are provided by the water chemical treatment supplier and that proper personal protective equipment (PPE) is available as recommended by the water chemical treatment supplier. Protective gloves and eyewear may be recommended as a precaution.

  • When removing or installing the manifold, hold the manifold by the sections specified in the illustration below.

Procedure

Complete manifold installation following the sequence: Install the manifolds→Reinstall the tray back to the enclosure→Perform manifolds bleeding.

Install the manifolds​

  1. Make sure all trays are removed from the enclosure. See Remove a tray from the enclosure.
  2. When installing a new lower manifold (blue-labeled hose), install the mani-conductor to it.
    Note

    Check the gap pad on the bottom of the mani-conductor, if it is damaged or detached, replace it with a new one. If installing a new mani-conductor, peel off the plastic film from the gap pad before installation.

    Figure 2. Mani-conductor gap pad

    1. Align the mani-conductor to the standoffs on the lower manifold; then, install the mani-condutor to the manifold.
    2. Install two T10 screws to secure the mani-conductor to the lower manifold.
    Figure 3. Installing the mani-conductor to a new lower manifold

  3. Install the lower manifold (blue-labeled hose).
    1. Install the lower manifold to the enclosure.
      Figure 4. Installing the lower manifold.

    2. Install twelve (x12) T10 screws to the lower manifold to secure it to the mid-plate.
      Figure 5. Installing screws to lower manifold

    3. Install two PH2 screws to secure the lower manifold to the enclosure.
      Figure 6. Installing screws to lower manifold

  4. Install the upper manifold (red-labeled hose).
    1. Install the upper manifold to the enclosure with an extended screwdriver.
      Figure 7. Installing the upper manifold

    2. Insert the tab on the manifold into the slot beneath the top of the enclosure.
      Figure 8. Inserting upper manifold tab into the slot on enclosure

    3. Install twelve (x12) T10 screws to the lower manifold to secure it to the mid-plate with an extended screwdriver.
      Figure 9. Installing screws to the upper manifold and enclosure

Reinstall the tray back to the enclosure​

  1. Place the tray into the enclosure.
    1. Rotate the tray handles to the open position.
    2. Insert the tray into the tray bay in the enclosure.
    Figure 10. Placing the tray into the enclosure

  2. Insert the tray into the tray bay while tray handles are in the open position.
    1. Rotate the tray handles to the open position.
    2. Push the tray into the enclosure until the handles bump into the enclosure edges.
    Figure 11. Pushing the tray into the enclosure until handles bump into enclosure edges

  3. Push the tray into the enclosure until the tip of the tray handle touches the enclosure. Make sure there is no distance between the enclosure and the tip of the handle.
    Figure 12. Checking tray handle position

    Figure 13. Distinguishing correct tray handle position

  4. Rotate the bottom handle for 45 degrees to push the tray slightly into the enclosure. DO NOT rotate the bottom handle all the way in.
    Note
    If the tray does not move into the enclosure as you rotate the bottom handle, the handles are not in correct position. Reinstall the tray until the handles are seated correctly and handle rotation can bring about tray movement.
    Figure 14. Slightly rotating bottom tray handle to move the tray forward

  5. Rotate both top and bottom handles to the closed position to secure the tray in the enclosure.
    Figure 15. Rotating both tray handles to the closed position

  6. Make sure the tray does not protrude from the enclosure. The surface of the tray front bezel and the enclosure outer frame should be aligned as a flat surface.
    Figure 16. Tray front bezel and enclosure outer frame surface alignment

Perform manifolds bleeding​

  1. Reinstall the following components back to the enclosure: .
    1. Install all Power Conversion Station (PCS) cage. See Install a Power Conversion Station (PCS) cage.
    2. Install all Power Conversion Stations (PCS). See Install a Power Conversion Station (PCS).
    3. Install all trays into the front of the enclosure. See Install a tray in the enclosure.
    Attention
    Do not connect power cords to the PCS when performing manifold draining and bleeding process.
  2. Make sure all power cords are disconnected from the PCS.
  3. Close the valve of the upper bleeder.
    Figure 17. Closing the valve of the upper bleeder

  4. Remove the cover from bleeder port on the upper manifold. Then, connect the upper bleeder to the bleeder port.
    Figure 18. Connecting upper bleeder to the bleeder port on the upper manifold

  5. Connect the facility supply hose to the lower manifold.
    Figure 19. Connecting facility supply hose to the lower manifold

  6. Partially open the valves of the lower manifold and the facility supply hose.
    1. Press the button on the ball valve switch
    2. Partially rotate the switch to open the valve, about 1/4 of the way.
    Note
    Do not fully open the ball valves or you will reduce your ability to control the flow as you fill the rack.
    Figure 20. Partially open the valves of the lower manifold and the facility supply hose

  7. Slowly open the valve of the upper bleeder to allow a steady stream of water to drain.
    Figure 21. Opening the valve of the upper bleeder

  8. Close the valve of the upper bleeder after a steady stream of water flows into the bucket or there are only minimal bubbles in the bleeder hose.
    Figure 22. Closing the valve of the upper bleeder

  9. Disconnect the upper bleeder from the upper manifold. Reinstall the cover to the bleeder port.
    Figure 23. Disconnecting upper bleeder from manifold

  10. Connect the facility return hose to the upper manifold.

  11. Open the valves of the upper manifold and the facility return hose.
    1. Press the button on the ball valve switch
    2. Rotate the switch to open the valves as illustrated below.
