  • Half length, low profile, single-wide: NVIDIA T4, P620, A2, L4

Note
  • For GPU supporting matrix, see Server models with GPUs.

  • 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.

    For the method of changing the Misc setting, see https://support.lenovo.com/us/en/solutions/TT1832.
System fans
  • Supported fan types:
    • Standard fan (60 x 60 x 36 mm, single-rotor, 17000 RPM)

    • Performance fan (60 x 60 x 56 mm, dual-rotor, 19000 RPM)

    • One CPU: five hot-swap system fans (4+1 redundancy, one redundant fan rotor)

    • Two CPUs: six hot-swap system fans (5+1 redundancy, one redundant fan rotor)

Note
  • Single-rotor hot-swap fans cannot be mixed with dual-rotor hot-swap fans.

  • When the system is powered off but still plugged in to AC power, fans 1 and 2 may continue to spin at a much lower speed. This is the system design to provide proper cooling.

Electrical input
The server supports up to two power supplies for redundancy.
