Power Supplies And Cables - Lenovo ThinkSystem SR650 Product Manual

Cooling
The SR650 server supports up to six hot-swap system fans that provide N+1 cooling redundancy. SR650 server
models with one processor include five system fans, and server models with two processors include six system
fans.
Configuration note: If Intel Xeon 6137, 6144, 6146, 6154, 8168, 8180, and 8180M processors are installed in the
server, the server performance might be impacted in case of a system fan failure.
The following table shows additional cooling options for configurations with the M.2 5100 SSDs, GPUs, and other
full-length PCIe adapters.

Description
ThinkSystem M.2 480GB SSD Thermal Kit
ThinkSystem SR650 GPU Thermal Kit
ThinkSystem SR650 2nd GPU Upgrade Kit
ThinkSystem SR650 GPU 1U Heatsink Option Kit
ThinkSystem SR650 P4 GPU Additional Air Duct Upgrade Kit
ThinkSystem SR650 V100 FHHL Air Duct Companion Kit
Configuration notes:
The M.2 SSD Thermal Kit (4XH7A08791) is required when at least one M.2 5100 480GB SSD (7SD7A05703)
is installed in the server; however, the SSD Thermal Kit is not required if a full-length, double-wide GPU
adapter is installed in the PCIe slot 5.
The M.2 SSD Thermal Kit is derived by the configurator if M.2 SSDs are selected in the initial configurations
of server models. For field upgrades of server models, the M.2 SSD Thermal Kit should be purchased with
M.2 drives.
The P600 and P620 GPU adapters do not require any thermal kits.
The full-length PCIe adapters and GPU adapters other than P600 or P620 require one of the following
thermal kits depending on the configuration:
The GPU Thermal Kit (7XH7A05897) is required when adding GPUs or full-length PCIe adapters to
the SR650 server models without factory-installed GPUs or factory-enabled full-length support. The
kit provides support for up to two GPUs or full-length adapters and contains an air duct, two low-
profile heatsinks, and two full-length card holders.
The 2nd GPU Upgrade Kit (7XH7A05899) is required when adding the second GPU or full-length
adapter to the SR650 server models with the factory-enabled full-length support with one riser card
or one factory-installed GPU. The kit provides support for the second GPU or full-length adapter and
contains a full-length card holder (the second riser card is not included in the kit).
The GPU 1U Heatsink Option Kit (7XH7A05898) is required when adding the second processor to the
SR650 server models with one processor and the factory-enabled full-length support or one factory-
installed GPU. The kit contains a low-profile heatsink for the second processor option.
The P4 GPU adapters require the P4 GPU Additional Air Duct Upgrade Kit (4XH7A08776) in addition to one
of the thermal kits described above. One air duct upgrade kit is required per P4 GPU adapter.
The V100 FHHL GPU adapters require the V100 FHHL Air Duct Companion Kit (4XH7A08792) in addition to
one of the thermal kits described above. One air duct kit is required when one V100 FHHL GPU adapter is
installed in the server, and two air duct kits are required when two or three V100 FHHL GPU adapters are
installed in the server.

Power supplies and cables

The SR650 server supports up to two redundant power supplies, and is capable of N+N redundancy depending on
the configuration. A second power supply can be added to the models that come with one power supply.
