How to Power Off the Server

  1. To gracefully power off the server from full power mode to standby power mode, use one of the following methods:
    • Use the operating system-specific shutdown procedure for the OS running on your server. Most operating systems have a shutdown procedure. This shutdown procedure provides a graceful shutdown of the OS, and it should be your first choice for powering off the server.

    • Use the ILOM web interface or command-line interface. See Controlling Server Power Remotely.

    • To gracefully power off the server from main power mode to standby power mode using the Power button, quickly press and release the Power button on the front panel.


      Caution

      Caution - Potential data loss. Pressing and releasing the Power button causes Advanced Configuration and Power Interface (ACPI) enabled operating systems to perform an orderly shutdown of the operating system. Servers not running ACPI–enabled operating systems perform an emergency shut down to standby power mode.


    When the main power is off and the server is in standby power mode, the Power OK LED on the front panel blinks, indicating that standby power is still available.


    Note - In standby power mode, power is still directed to some components. To completely power off the server, you must disconnect the AC power cords from the back panel of the server.


  2. To perform an emergency shutdown of the server power, press and hold the Power button for four seconds to force main power off.

    The server enters standby power mode.


    Caution

    Caution - Potential data loss. Pressing and holding the Power button for four seconds performs an immediate shutdown of the server. The system does not prompt for confirmation, nor are you allowed to save and exit open applications.
