Setting the redundant power supply mode

Use the Redundant Power Supply Mode option to set how the system handles redundant power supply configurations. All High Efficiency Mode settings provide the most power efficient operation when you are using redundant power supplies by keeping half of the power standby mode at lower power usage levels. Balanced Mode shares the power delivery equally between all installed power supplies.
