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.
• 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:

• Torx T10 head screwdriver
• Torx T15 head screwdriver
• Phillips #1 head screwdriver
• Phillips #2 head screwdriver
• Flat head screwdriver
• Alcohol cleaning pad
• 2 x H100/H200 PCM Kit
• 2 x SR780a V3 water loop putty pad kit
• SR780a V3 water loop service kit
• NVSwitch PCM Kit
• NVSwitch putty pad Kit
• GPU baseboard handles

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

Firmware and driver download: You might need to update the firmware or driver after replacing a component.

• Go to Drivers and Software download website for ThinkSystem SR780a V3 to see the latest firmware and driver updates for your server.

• Go to Update the firmware for more information on firmware updating tools.

The following illustration shows the GPU numbering and corresponding slot numbering in XCC.

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 GPUs onto the GPU baseboard.
   1. Carefully lay the GPU baseboard on a flat, static protective surface.
   2. Gently place the GPU down onto the GPU baseboard.
   3. Follow the sequence shown in the illustration below to fasten the four Torx T15 screws to secure the GPU to the GPU baseboard.
      Note

      First set the torque screwdriver to 0.1-0.12 newton-meters, 0.9-1.1 inch-pounds to fasten the screws for a few rounds. Then set the torque screwdriver to 0.58-0.62 newton-meters, 5-5.5 inch-pounds to fully fasten the screws.

   4. Repeat to install all the GPUs.
3. Install the GPU complex.
   1. Hold the handles (1) on both sides of the GPU baseboard in the correct orientation as illustrated; then, align the GPU complex with the seventeen standoffs on the GPU complex adapter plate, and carefully place it onto the adapter plate.

4. Follow the sequence shown in the illustration below to fasten the seventeen Torx T15 captive screws to secure the GPU complex.
   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.

6. Install the PCIe switch shuttle.
   1. Press the two lock latches on both sides of the PCIe switch shuttle.
   2. Push the PCIe switch shuttle into the chassis until it stops.
   3. Rotate the two release levers until they lock into place.
