Remove the H100/H200 GPU baseboard

Follow instructions in this section to remove the H100/H200 GPU baseboard. The procedure must be executed by a trained technician.

Procedure

1. Make preparation for this task.
   1. Remove all the power supply units. See Remove a hot-swap power supply unit.
   2. Remove all the front fans. See Remove a front hot-swap fan.
   3. Remove all the 2.5-inch hot-swap drives and the drive bay fillers (if any) from the drive bays. See Remove a 2.5-inch hot-swap drive.
   4. Pull the 8U GPU shuttle out of the chassis, and place it onto the lift platform. See Remove the 8U GPU shuttle.
   5. Remove the cable cover. See Remove the cable cover.
   6. Remove the power complex. See Remove the power complex.
   7. If the rear support bracket is installed, remove it.
      1. Unfasten the four screws marked with A on both sides of the 8U GPU shuttle.
      2. Remove the rear support bracket from the 8U GPU shuttle.

   8. Remove all the rear fan control board assemblies. See Remove a rear fan control board assembly.
   9. Remove all the GPU air ducts. See Remove an H100/H200 GPU air duct.
   10. Disconnect the cables from the GPU baseboard.
   11. Remove all the GPU and heat sink modules. See Remove an H100/H200 GPU and heat sink module.
2. Disengage the PCIe switch shuttle from the 8U GPU shuttle.
   1. Press the two blue release latches.
   2. Rotate the two release levers until they are perpendicular to the PCIe switch shuttle.
   3. Pull the PCIe switch shuttle forward until it stops.
      Important

      Push the two release levers back until they lock into place after pulling out the PCIe switch shuttle to avoid damage.

3. Flip over the front PCIe switch cable harness.
   1. Unfasten the ten screws marked with C on both sides of the 8U GPU shuttle.
   2. Flip over the front PCIe switch cable harness, and gently place it on the I/O cover.

4. Unfasten the seventeen Torx T15 captive screws on the GPU baseboard.
   Note

   Loosen or tighten the screws with a torque screwdriver set to the proper torque. For reference, the torque required for the screws to be fully loosen or tighten is 0.6 newton-meters, 5.3 inch-pounds.

5. Remove the GPU baseboard.
   1. Extend the two handles (1) on both sides of the GPU baseboard.
   2. Hold the two handles (1), and lift the GPU baseboard out of the 8U GPU shuttle.
