Option Values: Disabled
Auto
Fixed
Help Text: Allows a delay in powering up after a power failure, to reduce peak
power requirements. The delay can be fixed or automatic between 25-300 seconds.
Comments: When the AC power resume policy (above) is either Power On or Last
State, this option allows a delay to be taken after AC power is restored before the system
actually begins to power up. This delay can be either a fixed time or an “automatic” time, where
“automatic” means that the BIOS will select a randomized delay time of 25-300 seconds when
it sends the Power Restore Delay setting to the BMC.
This option will be grayed out and unavailable when the AC power resume policy is Stay Off.
The Power Restore Delay setting is maintained by BIOS. This setting does not take effect until
a reboot is done. Early in POST, the Power Restore Policy is read from the BMC, and if the
policy is Power On or Last State, the delay settings are sent to the BMC.
Bear in mind that even if the Power Restore Delay is Disabled, there will still be a delay of
about 20 seconds while the BMC itself boots up after AC power is restored.
Note: This Power Restore Delay option applies only to powering on when AC is applied. It has
no effect on powering the system up using the Power Button on the Front Panel. A DC power
on using the Power Button is not delayed.
The purpose of this delay is to avoid having all systems draw “startup surge” power at the same
time. Different systems or racks of systems can be set to different delay times to spread out the
startup power draws. Alternatively, all systems can be set to Automatic, and then each system
will wait for a random period before powering up.

6. Power Restore Delay Value
Option Values: [Entry Field 25 – 300, 25 is default]
Help Text: Fixed time period 25-300 seconds for Power Restore Delay.
Comments: When the power restore policy is Power On or Last State, and the Power
Restore Delay selection is Fixed, this field allows for specifying how long in seconds that fixed
delay will be.
When the Power Restore Delay is Disabled or Auto, this field will be grayed out and
unavailable.
The Power Restore Delay Value setting is maintained by BIOS. This setting does not take effect
until a reboot is done. Early in POST, the Power Restore Policy is read from the BMC, and if
the policy is Power On or Last State, the delay settings are sent to the BMC. When the Power
Restore Delay setting is Fixed, this delay value is used to provide the length of the delay.
