Remove a GPU

Use this information to remove a GPU.

About this task

shock hazard
Electrical current from power, telephone, and communication cables is hazardous.

To avoid a shock hazard:

  • Connect all power cords to a properly wired and grounded electrical outlet/source.
  • Connect any equipment that will be attached to this product to properly wired outlets/sources.
  • When possible, use one hand only to connect or disconnect signal cables.
  • Never turn on any equipment when there is evidence of fire, water, or structural damage.
  • The device might have more than one power cord, to remove all electrical current from the device, ensure that all power cords are disconnected from the power source.
  • Read the following sections to ensure that you work safely.
  • Turn off the corresponding DWC tray that you are going to perform the task on.
    If Shared I/O adapters are installed, power off the auxiliary node (node 1/3/5/7/9/11) first, and then power off the primary node (node 2/4/6/8/10/12).
  • Disconnect all external cables from the enclosure.
    Use extra forces to disconnect QSFP cables if they are connected to the solution.
  • To avoid damaging the water loop, always use the water loop carrier when removing, installing or folding the water loop.

  • A torque screwdriver is available for request if you do not have one at hand.

Prepare the following screwdrivers to ensure you can install and remove corresponding screws properly.

  1. Make preparations for this task.
    1. Remove the tray (see Remove a DWC tray from the enclosure).

      For safety, use the lift tool to remove the tray from the rack.

    2. Remove the tray cover (see Remove the tray cover).
    3. Remove the front and the rear cross braces (11x Phillips #1 screws).

    4. See Cable removal order to disconnect cables according to your configuration.
    5. Disconnect GPU power cable.

    6. Remove the clamp plate or the drive depending on your configuration.
    7. Remove seven Torx T10 water loop screws with a torque screwdriver sets to the proper torque.
      For reference, the torque required for the screws to be fully tightened/removed is 0.5-0.6 newton-meters, 4.5-5.5 inch-pounds.

    8. Remove GPU cold plate screws (16x Phillips #1 screws) with a torque screwdriver sets to the proper torque.
      For reference, the torque required for the screws to be fully tightened/removed is 0.34-046 newton-meters, 3-4 inch-pounds.

    12. Fold the water loop.
      1. ❶ Carefully unhook the quick connect and slide it out of the opening in the rear of the tray; then, lift the water loop up off the GPU board.

      2. ❷ Carefully rotate the water loop so one half is sitting on top of the other half.

  2. Locate the GPU which should be moved; then, remove the four Phillips #2 screws (with a torque screwdriver sets to the proper torque) and carefully remove the GPU out of the GPU board.
    For reference, the torque required for the screws to be fully tightened/removed is 0.45-0.56 newton-meters, 4-5 inch-pounds.
