Power Off Host Using the Power Button
Power State Description
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).
■
To use the power button, see “Power Off Host Using the Power Button” on page 52 and
“Power On Host Using the Power Button” on page 53.
■
To use Oracle ILOM, see “Power Host On and Off (Oracle ILOM)” on page 53.
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)” on page 229.
Power Off Host Using the Power Button
1.
Locate the recessed Power button on the server front panel.
See your installation manual for the location.

Press the Power button.
Use a stylus or other pointed, non-conducting object if required.
■ To perform a graceful shutdown: Press and release the power button.
ACPI-enabled operating systems perform an orderly shutdown. Systems not running
ACPI-enabled operating systems might ignore this event, and fail to shut down the host.
The OK status indicator on the front panel blinks to indicate that the system is in Standby
power mode.
■ To perform an immediate shutdown: Press and hold the Power button for at
least 5 seconds.
The OK status indicator on the front panel blinks to indicate that the system is in Standby
