Passwords v Exit Setup Select this choice to exit from the Configuration/Setup Utility program. If you have not saved the changes you have made in the settings, you are asked whether you want to save the changes or exit without saving them. From the System Security choice, you can set, change, and delete a power-on (user) password and an administrator (supervisor) password. The System Security choice is on the full Configuration/Setup 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 Configuration/Setup Utility menu. An administrator password is intended to be used by a system administrator; it limits access to the full Configuration/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 Configuration/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 Configuration/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 Configuration/Setup Utility menu; the user can set, change, and delete the power-on password, if the system administrator has given the user that authority. User password If a user password is set, when you turn on the server, the system startup will not be completed until you type the user password. You can use any combination of up to seven characters (A-Z, a-z, and 0-9) for the password. When a user password is set, you can enable the Unattended Start mode, in which the keyboard and mouse remain locked but the operating system can start. You can unlock the keyboard and mouse by typing the user password. Administrator password If an administrator password is set, you must type the administrator password for access to the full Configuration/Setup Utility menu. You can use any combination of up to seven characters (A-Z, a-z, and 0-9) for the password. Resetting passwords If you forget the user password, you can regain access to the server in any of the following ways: v If an administrator password is set, type the administrator password at the password prompt. Start the Configuration/Setup Utility program and reset the user password. v Remove the server battery and then reinstall it. See the Option Installation Guide for instructions for removing the battery. v Change the pin position of the clear CMOS (password override) jumper on the system board to bypass the user password check. See the Installation Guide for the location of the clear CMOS jumper. Chapter 2. Configuring the server 17
