If you enter the power-on password, you can view limited information in the Configuration/Setup Utility program, but you cannot change any settings. Using the Enhanced Security features With enhanced security, your administrator password and drive-startup sequence are stored in a highly protected, nonvolatile, security EEPROM module. When your administrator password and drive-startup sequence are stored in the security EEPROM, they remain intact even if the battery expires or is removed. Attention administrator password users: If enhanced security is enabled, and you forget or lose the administrator password, you must replace the system board in your server to regain access to the Configuration/Setup Utility program. If enhanced security is enabled and you have set an administrator password, your server will operate as follows: The security EEPROM is protected from unauthorized access once the startup procedures are complete. With enhanced security disabled, the contents of the EEPROM are write protected, and the server can function in a network environment because the POST/BIOS utility program will allow updates to the system programs. With enhanced security enabled, the POST/BIOS utility program will not allow updates to the system programs.
