HP Integrated Lights-Out 3 - Manual (Page 145)

To change the server power state by using the Virtual Power Button options, you must have the
Virtual Power and Reset privilege. Some of the power control options do not shut down the operating
system gracefully. Before you use the Virtual Power Button options, you must use the Remote Console
to initiate an operating system shutdown.
To change the server power state:
1.
Navigate to the Power Management
→Server Power page, as shown in
Figure 77 (page 145) .
Figure 77 Server Power page
2. Click one of the following buttons:
•
Momentary Press—The same as pressing the physical power button. If the server is
powered off, a momentary press will turn the server power on.
Some operating systems might be configured to initiate a graceful shutdown after a
momentary press, or to ignore this event. HP recommends using system commands to
complete a graceful operating system shutdown before you attempt to shut down by using
the Virtual Power button.
•
Press and Hold—The same as pressing the physical power button for 5 seconds and then
releasing it.
The server is powered off as a result of this operation. Using this option might circumvent
the graceful shutdown features of the operating system.
This option provides the ACPI functionality that some operating systems implement. These
operating systems behave differently depending on a short press or long press.
•
Reset—Forces the server to warm-boot: CPUs and I/O resources are reset. Using this
option circumvents the graceful shutdown features of the operating system.
•
Cold Boot—Immediately removes power from the server. Processors, memory, and I/O
resources lose main power. The server will restart after approximately 6 seconds. Using
this option circumvents the graceful shutdown features of the operating system.
NOTE: The Press and Hold, Reset, and Cold Boot options are not available when the server
is powered down.
