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.
Power supplies support AC (Worldwide) and HVDC (China only) power sources.
Important: The Standalone Solution Configuration Tool (SSCT) and Lenovo Enterprise Solutions
Configurator (LESC) power supply selection rules allow a subset of possible configurations due to power
restrictions. Configurations that cannot be built in SSCT or LESC 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 Lenovo Capacity
