Server Power States
Your server has three power states: powered off, Standby power, and Full power.
|
|
|
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).
