LENOVO ThinkSystem SR630 V2/SR645 Standard Fan Option Kit

Lenovo ThinkSystem SR630 v2 Standard 1 x Fan Option Kit

Cooling

The SR630 V2 server has up to eight 40 mm dual-rotor hot-swap fans, and the fans are N+1 rotor redundant. The fans are dual-rotor counter-rotating units, which means that the fans have two separate propellors, one in front of the other, and that the propellors rotate in opposite directions. Six fans are needed when one processor is installed and eight fans are required when two processors are installed. The server also has one additional fan integrated in each of the two power supplies.

Depending on the configuration, the server will need either all Standard fans (21K RPM) or all Performance fans (28K RPM).

Performance fans are required if the server has any of these components:

Processors with TDP > 165 W
Front 10x 2.5-inch AnyBay drive backplane
Front 16x EDSFF drive backplane
Rear 2x 2.5-inch backplane
NVIDIA A2, NVIIDIA T4 or any other passive GPU (GPU without its own internal fan)
Any of the following OCP adapters installed:
ThinkSystem Broadcom 57454 10GBASE-T 4-port OCP Ethernet Adapter
Any of the following PCIe adapters installed:
ThinkSystem Broadcom 57508 100GbE QSFP56 2-port PCIe 4 Ethernet Adapter
Mellanox ConnectX-6 Dx 100GbE QSFP56 2-port PCIe Ethernet Adapter
Mellanox ConnectX-6 HDR100 IB/100GbE VPI 1-port x16 PCIe 3.0 HCA
Mellanox ConnectX-6 HDR100 IB/100GbE VPI 2-port x16 PCIe 3.0 HCA
Mellanox ConnectX-6 HDR IB/200GbE Single Port x16 PCIe Adapter

Fans spin when server is powered off: If there is an OCP 3.0 Ethernet adapter installed, 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 for the OCP 3.0 Ethernet adapter.
