  • Single-wide: NVIDIA A2, T1000, T400, L4

Note

  • For GPU supporting rules, see Thermal rules.

  • 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 ESE122T or later.

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

    • One VGA connector (optional)

    • One USB 3.2 Gen1 (5 Gbps) connector

    • One USB 2.0 connector with XCC system management function

    • One external diagnostics connector

Network

  • OCP module in the front or rear of the server, which provides two or four Ethernet connectors for network support

    Note
    If the ThinkSystem V3 Management NIC Adapter Kit (management NIC adapter) is installed on the server, it will not be displayed on the PCIe card list of system management software, such as XCC, LXPM, and so on.
System fan
  • 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, 21000 RPM)

  • Fan redundancy: N+1 redundancy, one redundant fan rotor

    • One processor: five hot-swap system fans (one redundant fan rotor)

    • One processor with middle/rear bay or Riser 3, or two processors: six hot-swap system fans (one redundant fan rotor)

Note

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

  • The redundant cooling by the fans in the server enables continued operation if one rotor of a fan fails.

  • 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.

Power supplies
The server supports up to two hot-swap power supplies for redundancy.
