Shutdown Method
Graceful shutdown Use a pen, or other pointed object, to press and release the Power button on the
front panel. Pressing 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 will shut down to standby power mode immediately.
Emergency shutdown Press and hold the Power button for at least four seconds until the main power is
off and the server enters standby power mode. See
FIGURE 2-2.
When the main power is off, the Power/OK LED on the front panel flashes,
indicating that the server is in standby power mode.
Caution - All applications and files will be closed abruptly without saving
changes. File system corruption might occur.

Command Line” on page 2-4.
