Install the H100/H200 GPU baseboard

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

About this task

Attention
  • Read Installation Guidelines and Safety inspection checklist to ensure that you work safely.
  • Touch the static-protective package that contains the component to any unpainted metal surface on the server; then, remove it from the package and place it on a static-protective surface.
  • Two people and one lifting device on site that can support up to 400 lb (181 kg) are required to perform this procedure. If you do not already have a lifting device available, Lenovo offers the Genie Lift GL-8 material lift that can be purchased at Data Center Solution Configurator. Make sure to include the Foot-release brake and the Load Platform when ordering the Genie Lift GL-8 material lift.
  • Make sure to inspect the connectors and sockets on the GPU and the GPU baseboard. Do not use the GPU or the GPU baseboard if its connectors are damaged or missing, or if there are debris in the sockets. Replace the GPU or the GPU baseboard with a new one before continuing the installation procedure.
Note
Make sure you have the required tools listed below available to properly replace the component:
  • Torque screwdriver which can be set to 0.6 newton-meters, 5.3 inch-pounds
  • Torx T15 extended bit (6-inch long)
Firmware and driver download: You might need to update the firmware or driver after replacing a component.

Procedure

  1. (Optional) Remove the new GPU baseboard from the package box.
    1. Extend the two handles on both sides of the GPU baseboard.
    2. Hold the two handles, and remove the GPU baseboard out from the package box.

  2. Install the GPU baseboard.
    1. Hold the handles (1) on both sides of the GPU baseboard in the correct orientation as illustrated; then, align the GPU baseboard with the seventeen standoffs on the GPU complex adapter plate, and gently place it onto the adapter plate.
    2. Push the two handles (1) down.

  3. Follow the sequence shown in the illustration below to fasten the seventeen Torx T15 captive screws to secure the GPU baseboard.
    Important
    Do not overtighten the screws to avoid damage.
    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.

  4. Flip over the front PCIe switch cable harness.
    1. Flip over the front PCIe switch cable harness, and make sure that it correctly engages the four guide pins on the 8U GPU shuttle.
    2. Locate the ten screw holes marked with C on both sides of the 8U GPU shuttle; then, fasten the ten screws to secure the front PCIe switch cable harness.
