Server Power States
The server has the following power states.
|
|
|
Powered off
|
The server is completely powered off only when the power cords are
disconnected.
|
|
Standby power
|
In Standby power mode, the host is powered off, while the service
processor is powered on. The System OK LED on the front panel
blinks.
|
|
Main power
|
When you power on the host, the server enters Main power mode. In
Main power mode, the System OK LED 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.
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
Updating System Firmware Using Oracle ILOM.
