Description
The server is completely powered off only when the power cords are
disconnected.
In Standby power mode, the host is powered off, while the service processor is
on. The green OK status indicator on the front panel blinks.
When you power on the host, the server enters Full power mode. In Full power
mode, the green OK status indicator is steady on.
You can power the host off gracefully, or immediately.
When you power off the server gracefully, Advanced Configuration and Power
Interface (ACPI)-enabled operating systems prepare the operating system before
shutting it down. When you power the server off immediately, no such attempt
occurs.
