Secure Mode
Configure and enable the secure boot mode by using the SSU. When secure mode
is in effect:
• You can boot the server and the operating system will run, but you must enter
the user password to use the keyboard or mouse.
• You cannot turn off system power or reset the server from the front panel
switches.
Secure mode has no effect on functions enabled via remote server management or
power control via the watchdog timer.
Taking the server out of secure mode does not change the state of system power.
That is, if you press and release the power switch while secure mode is in effect, the
system will not be powered off when secure mode is later removed. However, if the
front panel power switch remains depressed when secure mode is removed, the
server will be powered off.
