Power Modes, Shutdowns, and Resets
This section contains information about power modes, server shutdowns, and server resets.
Full Power Mode
When the server enters full power mode, power is supplied to all the server components, the
server boots, and the operating system (OS) functions. This is the normal operating condition
for the server. The Power OK and SP OK indicators are steady on.
To enter full power mode, press the Power button on the server front panel when the server is
in standby power mode. You can also enter full power mode by powering on the server from
Oracle ILOM.
Standby Power Mode
In standby power mode, low-level power is supplied only to the components required to run the
SP. The OS does not boot.
To enter standby power mode, either:
■
Connect the AC power cables to the back of the server but do not press the Power button.
■
From full power mode, either press the front panel power button, or use Oracle ILOM.
When you connect power to the server, the SP boots. The SP OK indicator blinks while the SP
is booting, then remains steady on once it has booted. The Power OK indicator flashes briefly
every 3 seconds.
Graceful Shutdown
A graceful shutdown (also referred to as an orderly shutdown) closes files and prepares the
file system before it shuts down the server to standby power mode. This is the safest method of
shutting down the server.
To perform a graceful shutdown use the server OS, Oracle ILOM, or the server front panel
Power button.
