remaining installed power supplies.
Power settings
The Power Settings page enables you to view and control the power management features of
the server. The power management features on this page vary based on the server configuration.
Power Regulator settings
The Power Regulator feature enables iLO to modify processor frequency and voltage levels
based on operating conditions, to provide power savings with minimal effect on performance.
The Power Settings page allows you to view and control the power regulator mode.
Prerequisites
• Configure iLO Settings privilege
• An iLO license that supports this feature is installed. For more information, see the following
website: http://www.hpe.com/info/ilo/licensing.
• The server is not in POST. The Power Regulator settings cannot be changed while the server
is in POST.
Configuring the Power Regulator settings
1. Navigate to the Power Management→Power Settings page.
2. Select a Power Regulator mode.
3. Click Apply.
• For the Dynamic Power Savings Mode, Static Low Power Mode, and Static High
Performance Mode settings, iLO notifies you that the Power Regulator settings changed.
• For the OS Control Mode setting, iLO notifies you that you must reboot the server to
complete the Power Regulator settings change.
If the settings do not change after you click Apply, the server might be in the boot process
or require rebooting. Exit any ROM-based program that is running, allow POST to complete,
and then try again.
4. If iLO notified you that a reboot is required, reboot the server.

Power Regulator modes
Choose from the following modes when you configure the Power Regulator settings:
• Dynamic Power Savings Mode—Automatically varies processor speed and power usage
based on processor utilization. This option allows the reduction of overall power consumption
with little or no impact to performance. It does not require OS support.
• Static Low Power Mode—Reduces processor speed and power usage. This option
guarantees a lower maximum power usage for the system.
• Static High Performance Mode—Processors will run at maximum power/performance at
all times, regardless of the OS power management policy.
• OS Control Mode—Processors will run at maximum power/performance at all times, unless
the OS enables a power management policy.
