1.9 Installing physical GPUs

NCP-AII · System and Server Bring-up (31% of the exam) · Official objective: “Install physical GPUs.”

Safe handling, which parts are customer-replaceable and what to check before driver install.

Key points

  1. ESD (electrostatic discharge) is a static shock that can kill electronic parts. An ESD strap grounds you. Labels let you put every cable back where it was. NVIDIA also warns not to hold the tray by its ejection handles.

    What NVIDIA says (3)

    “Wear an ESD strap during any procedure that involves touching electronic components.”

  2. A CRU (customer-replaceable unit) is a part you may replace yourself. The DGX H100 list includes PSUs, fans, drives, DIMMs and some NICs. It does not include GPUs. For parts not covered, NVIDIA says to contact Enterprise Support.

    What NVIDIA says (2)

    “You can obtain the following components for replacement in your data center.”

  3. The NVIDIA driver builds kernel modules against the running kernel. NVIDIA's pre-installation actions are: check the distribution, install matching kernel headers, and pick a driver version.

    What NVIDIA says (2)

    “Verify the system is running a supported version of Linux.”

    “Verify the system has the correct kernel headers and development packages installed.”
