Power Modes

Full power mode is the normal operational mode for the server. When the server enters full power mode, power is supplied to all the server components, the server boots, and the operating system (OS) functions. You achieve full power mode by pressing the Power button on the front of the server when the server is in standby power mode. Once the server is operating in full power mode the Power OK LED is on continuously (does not blink).

Standby power mode is the non-operating mode. That is, the server is in a low-power or powered-down state and is not capable of booting and starting the OS. In standby power mode, minimum power is supplied only to the components that are required for lights-out management. You achieve standby power by connecting the server to an AC supply. In standby power mode, power is supplied to the service processor (SP), which allows the SP to boot. To sustain standby power mode, you must not press the front panel Power button. You can also achieve standby power mode by powering off the server (from an operational mode) using one of the power-off methods. When the server is in standby power mode, the Power OK LED on the front panel blinks.
