v Exit Setup
Select this choice to exit from the Setup utility. If you have not saved the
changes that you have made in the settings, you are asked whether you want to
save the changes or exit without saving them.
Passwords
From the User Security menu choice, you can set, change, and delete a power-on
password and an administrator password. The User Security choice is on the full
Setup utility menu only.
Attention: If you set an administrator password and then forget it, there is no way
to change, override, or remove it. You must replace the system board.
If you set only a power-on password, you must type the power-on password to
complete the system startup and to have access to the full Setup utility menu.
An administrator password is intended to be used by a system administrator; it
limits access to the full Setup utility menu. If you set only an administrator
password, you do not have to type a password to complete the system startup, but
you must type the administrator password to access the Setup utility menu.
If you set a power-on password for a user and an administrator password for a
system administrator, you can type either password to complete the system startup.
A system administrator who types the administrator password has access to the full
Setup utility menu; the system administrator can give the user authority to set,
change, and delete the power-on password. A user who types the power-on
password has access to only the limited Setup utility menu; the user can set,
change, and delete the power-on password, if the system administrator has given
the user that authority.
Power-on password
If a power-on password is set, when you turn on the server, the system startup will
not be completed until you type the power-on password. You can use any
combination of up to seven characters (A - Z, a - z, and 0 - 9) for the password.
If you forget the power-on password, you can regain access to the server in the
following way:
v If an administrator password is set, type the administrator password at the
password prompt. Start the Setup utility and reset the power-on password.
Attention: If you set an administrator password and then forget it, there is no
way to change, override, or remove it. You must replace the system board.
