About Power Modes

The Sun Fire X4640 server has two power modes, full-power mode and standby-power mode. In full-power mode, power is supplied to all the server components (for example, hard drives, fans, and PCI cards). Full-power mode is the normal operational mode for the server. When the server is in full-power mode, the server boots and the operating system (OS) functions. Full-power mode is achieved by pressing the power-on button on the front of the server when the server is in standby power mode.

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 (LOM). Standby power is achieved by connecting the server to an AC supply using the AC power cords. 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.
