Server Power States

Your server has three power states: powered off, Standby power, and Full power.

Power State
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.

Caution  -  Data loss: To prevent data loss, prepare the operating system for shutdown before performing an immediate power off.

You can control power to your host using the recessed Power button, the Oracle ILOM web interface, or the Oracle ILOM command-line interface (CLI).

Note -  If you updated the system firmware and selected the Delay BIOS Upgrade option, Oracle ILOM installs the BIOS firmware upgrade when you reset or power cycle your server. 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 BIOS and SP Firmware or CMM Firmware (Oracle ILOM).
