Intel® Server Board S1200V3RP BIOS Setup Interface System action to take on AC power loss recovery. [Stay Off] - System stays off. [Last State] - System returns to the same state before the AC power loss. [Power On] - System powers on. Comments: This option controls the policy that the BMC will follow when AC power is restored after an unexpected power outage. The BMC will either hold DC power off or always turn it on to boot the system, depending on this setting - and in the case of Last State, depending on whether the power was on and the system was running before the AC power went off. When this setting is changed in Setup, the new setting will be sent to the BMC. However, the BMC maintains ("owns") this Power Restore Policy setting, and it can be changed independently with an IPMI command to the BMC. BIOS gets this setting from the BMC early in POST, and also for the Setup Server Management screen. Back to [Server Management Screen] - [Screen Map] 5. Power Restore Delay 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. Revision 1.0 151

Intel® Server Board S1200V3RP
BIOS Setup Interface
System action to take on AC power loss recovery.
[Stay Off] - System stays off.
[Last State] - System returns to the same state before the AC power loss.
[Power On] - System powers on.
Comments:
This option controls the policy that the BMC will follow when AC
power is restored after an unexpected power outage. The BMC will either hold DC power
off or always turn it on to boot the system, depending on this setting – and in the case of
Last State, depending on whether the power was on and the system was running before
the AC power went off.
When this setting is changed in Setup, the new setting will be sent to the BMC. However,
the BMC maintains (“owns”) this Power Restore Policy setting, and it can be changed
independently with an IPMI command to the BMC. BIOS gets this setting from the BMC
early in POST, and also for the Setup Server Management screen.

5. Power Restore Delay
Option Values:
Disabled

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.
