Powering the Server On and Off
Your server has three power states: power off, standby power, and full power.
|
|
|
|
|
Power off
|
The server is completely powered off when the AC power cords are
disconnected.
|
All indicators are off.
The server is disconnected from all power sources.
|
Disconnect power cords to completely remove power.
Caution -
Equipment damage. Do not disconnect power cords when system is
in full power mode.
|
|
|
Standby power
|
When the server is in standby power mode, the service processor is
powered on but the host is powered off.
|
The system OK indicator blinks.
The service processor OK indicator is steady on.
|
If the server is completely powered off, plug in the power cords
to apply standby power.
If the server is in full power mode, use Oracle ILOM or the
recessed power button to remove host power.
You can power the host off gracefully, or immediately.
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 off 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.
|
|
Full power
|
When you power on the host, the server enters full power
mode.
|
In full power mode, the system OK indicator is steady on.
|
Use Oracle ILOM or the recessed power button to apply host
power.
