q Must enter the user password to enter BIOS Setup or the SSU.
q Must enter the user password to boot the server if Password on Boot is enabled
in either the BIOS Setup or SSU.
q Must enter the user password to exit secure mode.
If only the administrator password is set, you:
q Must enter the administrator password to enter BIOS Setup or the SSU.
q Must enter the administrator password to boot the server if Password on Boot is
enabled in either the BIOS Setup or SSU.
q Must enter the administrator password to exit secure mode.
If both passwords are set, you:

SSU and have access to all of the options.
q May enter either password to boot the server if Password on Boot is enabled in
either the BIOS Setup or SSU.

Secure Mode
Configure and enable the secure boot mode by using the SSU. When secure mode is in
effect:
q You can boot the server and the operating system will run, but you must enter
the user password to use the keyboard or mouse.
q You cannot turn off system power or reset the server from the front panel
switches.
Secure mode has no effect on functions enabled via the Server Manager Module or
power control via the real time clock. 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.
