Caution – To completely power off the server, you must disconnect the AC power

an orderly shutdown of the operating system. Servers not running ACPI-enabled
operating systems will shut down to standby power mode immediately.
Press and hold the Power button for at least four seconds until the main power is
off and the server enters standby power mode.
When the main power is off, the Power/OK LED on the front panel flashes,
indicating that the server is in standby power mode. See
CAUTION: All applications and files will be closed abruptly without saving
changes. File system corruption might occur.
