Power management

iLO 2 Power Management enables you to view and control the power state of the server, monitor power
usage, monitor the processor, and modify power settings. The Power Management page has four menu
options: Server Power, Power Meter, Processor States, and Settings. When you select Power
Management, the Server Power Controls page appears. The Server Power Controls page has two
sections: Virtual Power Button and Power Configuration Settings.
The Virtual Power Button section displays the current power state of the server as well as remote server
power control options. The displayed power state is the state of the server power when the page is first
opened. The server can be On, Off, or Reset. Use the browser refresh feature to keep the status of the
power indicator current.
To change the current server power state using the Virtual Power Button options, you must have the Virtual
Power and Reset privilege. Some of the power control options do not gracefully shut down the operating
system. An operating system shutdown should be initiated using the Remote Console before using the
Virtual Power Button options. The following options are available:
•
Momentary Press button provides behavior identical to pressing the physical power button.
•
Press and Hold is identical to pressing the physical power button for five seconds and then releasing
it. This option provides the ACPI-compatible functionality that is implemented by some operating
systems. These operating systems behave differently depending upon a short press or long press. The
behavior of this option might circumvent any graceful shutdown features of the operating system.
•
Cold Boot of the system immediately removes power from the system. The system will restart after
approximately six seconds. This option is not available when the server is powered down. This
option circumvents graceful operating system shutdown features.
•
Reset System initiates a system reset. This option is not available when the server is powered down.
The behavior of this option might circumvent any graceful shutdown features of the operating system.
The Power Configuration Settings section enables you control how the remote server powers up when
power is applied. The following options are available:
