Note

  • One CPU requires 6 fans (slot 1–6) and 2 fan dummies (7–8), but you can also install 8 fans for one CPU; two CPUs require 8 fans (slot 1–8).

  • If there is an OCP 3.0 Ethernet adapter installed, when the system is powered off but still plugged in to AC power, fans 5 and fan 6 will continue to spin at a much lower speed. This is the system design to provide proper cooling for the OCP 3.0 Ethernet adapter.
