• Not Enough Cooling—There is insufficient cooling available in the enclosure to cool the

power until it is allowed. Otherwise, press the momentary press button again.
• Power Hold by Manager Profile (Synergy compute modules only)—HPE OneView has
placed a power hold on this server.

For troubleshooting information, see the error messages guide for your server.
Managing the server power
The Virtual Power Button section on the Server Power page displays the current power state
of the server, as well as options for remotely controlling server power. System Power indicates
the state of the server power when the page is first opened. The server power state can be ON,
OFF, or Reset. Use the browser refresh feature to view the current server power state. The
server is rarely in the Reset state.
Prerequisites
Virtual Power and Reset privilege
Changing the server power state
1. Navigate to the Power Management→Server Power page.
2. Click one of the following buttons:
• Momentary Press
• Press and Hold
• Reset
• Cold Boot
The Press and Hold, Reset, and Cold Boot options are not available when the server is
powered off.
3. When prompted to confirm the request, click OK.
Virtual Power Button options
• Momentary Press—The same as pressing the physical power button. If the server is powered
off, a momentary press will turn on the server power.
Some operating systems might be configured to initiate a graceful shutdown after a
momentary press, or to ignore this event. Hewlett Packard Enterprise 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.
