Passwords Select this choice to display the server temperature and voltage status, and fan speeds. v Error Logs Select POST Error Log to view the three most recent error codes and messages that the system generated during POST. Select Clear event/error logs from the POST Error Log menu to clear the POST Error Log. v Save Settings Select this choice to save the changes you have made in the settings. v Restore Settings Select this choice to cancel the changes you have made in the settings and restore the previous settings. v Load Default Settings Select this choice to cancel the changes you have made in the settings and restore the factory settings. 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 password and an administrator 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 you 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. If you forget the power-on password, you can regain access to the server in any of the following ways: v If you have forgotten the user password and an administrator password is set, type the administrator password at the power-on prompt. Start the Configuration/Setup Utility program and change the user password. CAUTION: Before changing any switch settings or moving any jumpers, turn off the server; then, disconnect all power cords and external cables. 10 IBM xSeries 225 Types 8649: Hardware Maintenance Manual and Troubleshooting Guide
