System and Setup Password Features
NOTICE: The password features provide a basic level of security for the data on your system. If your data requires
more security, use additional forms of protection, such as data encryption programs.
NOTICE: Anyone can access the data stored on your system if you leave the system running and unattended
without having a system password assigned or if you leave your system unlocked so that someone can disable the
password by changing a jumper setting.
Your system is shipped to you without the system password feature enabled. If system security is a
concern, operate your system only with system password protection.
To change or delete an existing password, you must know the password (see "Deleting or Changing an
Existing System Password" on page 40). If you forget your password, you cannot operate your system or
change settings in the System Setup program until a trained service technician changes the password
jumper setting to disable the passwords, and erases the existing passwords. This procedure is described in
"Disabling a Forgotten Password" on page 123.
Using the System Password
After a system password is assigned, only those who know the password have full use of the system.
When the System Password option is set to Enabled, the system prompts you for the system password
after the system starts.
Assigning a System Password
Before you assign a system password, enter the System Setup program and check the System Password
option.
AC Power Recovery
(Last default)
Determines how the system reacts when power is restored to the system. If system
is set to Last, the system returns to the last power state. On turns on the system
after power is restored. When set to Off, the system remains off after power is
restored.
