Server Power States
Your server has three power states: powered off, Standby power, and Full power.
Power State Description
Powered off Servers are completely powered off only when the AC power cords are disconnected.
Server modules are completely powered off when they are disconnected from the chassis, or
when the AC power to the chassis is disconnected.
Standby power In Standby power mode, Oracle ILOM is powered on, but the host is powered off.
In Standby power mode, the OK status indicator on the front panel blinks.
Full power When you power on the host, the server enters Full power mode.
In Full power mode, the OK status indicator is steady on.
You can power the host off gracefully, or immediately.
When you power the host off gracefully, Advanced Configuration and Power Interface
(ACPI)-enabled operating systems prepare the operating system before shutting it down.
When you power the host off immediately, no such attempt occurs.
