  • Go over Installation Guidelines 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.

Note
The following adapters must be installed in the PCIe riser assembly.
  • ThinkSystem Broadcom 57454 10/25GbE SFP28 4-port PCIe Ethernet Adapter
  • ThinkSystem Broadcom 57454 10/25GbE SFP28 4-port PCIe Ethernet Adapter V2

Install an adapter on the system board​

Procedure

  1. Open the retention latch.
  2. If a filler has been installed in the PCIe slot, remove the screw that secures it, and remove the filler.
  3. Align the adapter with the connector on the system board, and push it in.
    Figure 1. Installing an adapter to the system board

  4. Secure the adapter with a screw.
  5. Close the retention latch.

Install an adapter in the PCIe riser assembly​

Note
  • When installing the following adapters:
    • Nvidia T4
    • Mellanox ConnectX-6 HDR 100/100GbE QSFP56 1-port PCIe VPI Adapter
    • Mellanox ConnectX-6 HDR 100/100GbE QSFP56 2-port PCIe VPI Adapter
    • Mellanox ConnectX-6 HDR/200GbE QSFP56 1-port PCIe 4 VPI Adapter
    make sure to adopt the following risers and PCIe slots, and do not install any other adapters to the risers:
    • Zone 1: slot 1 in x16/x16/x16 (x8 lanes) riser
    • Zone 2: slot 5 in x16/x16 riser
  • When installing two units of Nvidia T4, make sure to meet the following system requirements.
    • Maximal capacity of each memory module is 64 GB.
    • Maximal quantity depends on processors wattage:
      • Less than 165 watts: 48
      • 165 to 250 watt: 24
    • Maximal quantity of 2.5-inch drives is 16.
  • NVMe PCIe 4.0 x8 Flash Adapter has to be installed in slot 1, 5, 7, or 8.
  • When Nvidia T4 is installed:
    • If OCP Ethernet adapter is installed in slot 4, slot 7 is disabled.
    • If an adapter is installed in slot 7, slot 4 is disabled.
  • To prevent potential thermal issues, change the Misc setting in the BIOS from Option3 (default value) to Option1 if the following two conditions are met:

    • The server is equipped with a GPU adapter.

    • The UEFI firmware version is M5E128A or later.

    For the method of changing the Misc setting, see https://support.lenovo.com/us/en/solutions/TT1832.

Procedure

  1. Open the retaining bracket on the PCIe riser assembly.
  2. If a filler has been installed to the slot on the riser, remove the screw that secures it and remove the filler.
  3. Align the adapter with the connector on the PCIe riser assembly, and push it in.
