When this option is set to Disabled, you cannot use the power button to turn off the system or perform other system
events.
NOTICE: Use the NMI button only if directed to do so by qualified support personnel or by the operating system's
documentation. Pressing this button halts the operating system and displays a diagnostic screen.
NMI Button — Toggles the NMI feature On or Off.
Console Redirection Screen
This screen is used to configure the console redirection feature:
NOTE: It is recommended that you do not change the console redirection defaults.
Console Redirection — Toggles the console redirection feature On (default) or Off.

After you press to exit the System Setup program, the Exit screen displays the following options:
Save Changes and Exit

Using the System Password Feature
NOTICE: The password features provide a basic level of security for the data on your system. If your data requires
more security, it is your responsibility to obtain and use additional forms of protection, such as data encryption
programs.
NOTE: Dell recommends that the system password be left in the Not Enabled (default) setting. If the System
Password option is set to Enabled when operating your system in the headless configuration, you will not be able to
enter a system password in order to reboot the system.
NOTE: To use the System Setup program, connect a keyboard, monitor, and mouse to the system or use the console
redirection function on the serial port 1 (COM1) connector. See Figure 3-3 for the serial port location. See " Using
Console Redirection " for more information on console redirection.
Your system is shipped to you without the system password feature enabled. If system security is a concern, you should
operate your system only with system password protection.
You can assign a system password whenever you use the System Setup program. 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 just after the
system starts.
To change an existing system password, you must know the password (see " Deleting or Changing an Existing System
Password "). If you assign and later forget a system password, a trained service technician must remove the system cover to
change a jumper setting that disables the system password feature (see " Disabling a Forgotten Password "). Note that this
erases the setup password at the same time.
