An Administrator wants to change the PSU configuration In such a way that it can...

Within the iDRAC power management interface for Dell PowerEdge servers, configuring power supply unit (PSU) high availability requires setting a foundational redundancy policy. The proper policy to select is 'Redundant'. This policy ensures that the power subsystem can survive the loss of a single power feed or a hardware failure within an individual power supply unit. Once the 'Redundant' policy wrapper is globally enabled, advanced sub-settings such as the Hot Spare feature become available. The Hot Spare framework allows the administrator to prioritize specific power supplies, enabling the option to configure a primary PSU (such as PSU1) to carry the active operational load while placing secondary units (such as PSU2) into a lower-consumption standby sleep state. If the primary power supply encounters a failure or an input voltage interruption, the standby PSU instantly transitions to an active state to maintain uninterrupted server operations.
