Refer to the following section for more information on the PCS configurations.

SC750 V4 PCS configuration​

Validate the power requirements for your configuration using the latest version of the Power Configurator to ensure that the number of Power Conversion Stations selected are adequate for supporting your chassis configuration. The Power Configurator tool can be found at Lenovo Capacity Planner website.
CAUTION
Failure to validate the configuration with the Power Configurator tool could result in system errors, failure to power on, or microprocessor throttling, and limiting system's ability to leverage all the microprocessor performance.

ComponentSC750 V4 power policy

15000W Titanium DWC PCS

Supports up to four 15000W Power Conversion Stations (PCS):

  • The enclosure must be installed with at least three PCS.

  • Input voltage: 380 – 480 Vac (Acbel DWC PCS)

  • Redundancy: work as N+1 with OVS and N+N with OVS (OVS: oversubscription)

  • Resetting SMM3 to factory defaults will cause the PCS redundancy mode to return to the default N+1 mode. If needed, re-configure PCS redundancy mode as the original or as loading required via SMM3.

Note
Oversubscription (OVS) of the power system allows for more efficient use of the available system power.
