Power Control Options
40 Oracle X6 Series Servers Administration Guide • April 2016
Power State Description
Caution - Data loss: To prevent data loss, prepare the operating system for
shutdown before performing an immediate power off.
Note - If you updated the system firmware and selected the Delay BIOS Upgrade option,
when you reset or power cycle your server, Oracle ILOM installs the BIOS firmware upgrade.
This causes a reset to take longer than normal and causes the server to power cycle during the
reset. This is normal, expected behavior during a delayed BIOS upgrade. For more details, see
“Update the BIOS and Service Processor Firmware (Oracle ILOM)” on page 118.
Power Control Options
The server supports the following power control actions.
Power Control Action Description
Graceful shutdown Graceful shutdown allows ACPI-enabled operating systems to perform an
orderly shutdown. Servers not running ACPI-enabled operating systems might
ignore this event and fail to shut down.
Once the shutdown is completed, the green OK status indicator on the front panel
blinks to indicate that the server is in Standby power mode.
Immediate power off Immediate shutdown abruptly closes all applications and files without saving
changes.
Once the shutdown is completed, the green OK status indicator on the front panel
blinks to indicate that the server is in Standby power mode.
Reset Reset causes the server to reboot, while power remains applied to system
components (such as disk drives).
Power cycle Power cycle removes power from all system components, and then reverts the
server to Full power mode.
Power on Power on causes the server to enter Full power mode.
Powering the Server Off and On
You can power the server on and off locally or remotely. To power off the server locally, you
need access to the recessed power button on the front panel of the server. To power off the
server remotely, you need access to Oracle ILOM.
The following procedures describe how to power the server on and off:
