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.
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.
