Cooling
The System x3650 M5 server supports up to six system fans that provide dual fan zones cooling with N+1 fan
redundancy, and each system fan has one rotor.
System x3650 M5 server models with one processor include four system fans, and server models with two
processors include six system fans. An optional PCIe thermal solution kit is also required if any of the ML2
adapters are present in the configuration. The PCIe thermal kit contains an air baffle.
The following table shows additional cooling options.

General power supply rules are as follows:
Minimum of 1 and maximum of 2 power supplies per system.
If 2 are installed, power supplies must be identical.
Important: The Standalone Solution Configuration Tool (SSCT) and Lenovo Hardware Configurator power
supply selection rules allow a subset of possible configurations due to power restrictions. Configurations that
cannot be built in SSCT or Hardware Configurator due to power restrictions may still be supported. To verify
support and ensure that the right power supply is chosen for optimal performance, you should always validate
your server configuration using the latest version of the System x Power Configurator:
