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. 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. When a power-on 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 power-on password. If you forget the power-on 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 power-on password. v Remove the server battery and then reinstall it. For instructions for removing the battery, see the Problem Determination and Service Guide on the IBM xSeries Documentation CD. v Change the pin position of the clear CMOS jumper (JP2) on the system board to bypass the power-on password check. 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. The Administrator Password choice is on the Configuration/Setup Utility menu only if an optional IBM Remote Supervisor Adapter II is installed. Resetting passwords If you forget the power-on password, you can change the pin position of the clear CMOS jumper (JP2) on the system board to bypass the power-on password check. This enables you to reset the power-on password. However, if you forget the administrator password, you must replace the system board. Chapter 3. Configuring the server 55
