Note

  • The OCP module is an optional part. It is default to be installed on the rear and optional in the front of the server.

  • If the ThinkSystem V3 Management NIC Adapter Kit 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.

Rear button​

Rear button

  • NMI button

System fan

  • Supports up to seven dual-rotor hot-swap fans (including one redundant fan rotor)

  • Supports the following two fan types:

    • Standard fan 4056 (speed: 21000 RPM)

    • Performance fan 4056 (speed: 28000 RPM)

Note
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.

The server supports up to two power supplies for redundancy.
