You can shut down an x86 based system by pressing the power button. An ACPI event is then sent that alerts the system that the user has requested a shutdown. This method of turning the power off is equivalent to issuing a shutdown –i0 or an init 0 command.
For information about turning off power to devices, see the instructions for the specified hardware in the product documentation at https://www.oracle.com/products/oracle-a-z.html.
During the shutdown process, if the console=graphics option was used to boot the system, and the shutdown is triggered by the Xorg server, a progress status indicator is displayed. To bypass the progress status indicator, set the new splash-shutdown property of the svc:/system/boot-config SMF service to false, as follows:
$ svccfg -s svc:/system/boot-config:default setprop config/splash_shutdown = false $ svcadm refresh svc:/system/boot-config:default
