Technical rules for GPU adapters

Understanding the technical rules helps you choose the correct GPUs and install them in the supported slots based on what is configured for your server.

The following are rules for installing GPUs for your server:

  • For GPU configuration, the CPU TDP must not be greater than 200 W. However, if the 4 x 2.5'' SAS/SATA drive backplane is used or no backplane is used, the CPU TDP can support up to 270 W.

  • If a passive GPU adapter is used, the performance fan must be used.

  • Refer to the following slot priority when installing a GPU adapter:

    • T4, P620, A2, L4: slot 1, slot 3, slot 2

    • P2200: slot 2 (full-height)

  • When T4, L4 or A2 is installed, the ambient temperature must be limited to 30°C or lower.

  • Up to one P2200 GPU adapter is supported, while a maximum of three T4, L4, P620 or A2 GPU adapters are supported.

  • All GPUs installed must be identical.

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 AFE128B or later.
