power supply drops, the power supply in the sleep state returns to an active output state.
If having both power supplies active is more efficient than having one power supply in a sleep state, the
active power supply can also activate a sleeping power supply.
The default power supply settings are as follows:
If the load on the active power supply is more than 50%, then the redundant power supply is switched
to the active state.
If the load on the active power supply falls below 20%, then the redundant power supply is switched
to the sleep state
You can configure the Hot Spare feature using the iDRAC settings. For more information on iDRAC
