Install the GPU complex adaptor plate

Follow instructions in this section to install the GPU complex adaptor plate. 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.
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 (for H100 GPU complex) or 1.53 newton-meters, 13.5 inch-pounds (for MI300X GPU complex)
  • Torx T15 extended bit (6-inch long)

Procedure

  1. Align the GPU complex adaptor plate with the four guide pins in the bottom of the 8U GPU shuttle; then, lower the GPU complex adaptor plate into the 8U GPU shuttle.
  2. Locate the fourteen screw holes marked with an arrow; then, fasten the fourteen screws to secure the GPU complex adaptor plate.

  3. Install the GPU complex. Depending on the configuration, see Install the H100 GPU complex or Install the MI300X GPU complex.
  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.
