Using the System Setup Program

Dell™ PowerEdge™ SC1420 Systems User's Guide

After you set up your system, run the System Setup program to familiarize yourself with your system configuration and optional settings. Record the information for future reference.

You can use the System Setup program to:

Change the system configuration stored in NVRAM after you add, change, or remove hardware
Set or change user-selectable options—for example, the time or date
Enable or disable integrated devices
Correct discrepancies between the installed hardware and configuration settings

Entering the System Setup Program

Turn on or restart your system.
Press <F2> immediately after you see the following message:

<F2> = System Setup

If your operating system begins to load before you press <F2>, allow the system to finish booting, and then restart your system and try again.

NOTE: To ensure an orderly system shutdown, see the documentation that accompanied your operating system.

Responding to Error Messages

You can enter the System Setup program by responding to certain error messages. If an error message appears while the system is booting, make a note of the message. Before entering the System Setup program, see "System Beep Codes" and "System Messages" in your Installation and Troubleshooting Guide for an explanation of the message and suggestions for correcting errors.

NOTE: After installing a memory upgrade, it is normal for your system to send a message the first time you start your system.

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"). 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 the Installation and Troubleshooting Guide.

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, 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.

When a system password is assigned, the setting shown for the System Password option is Set. If the setting shown for the Password Status is Unlocked, you can change the system password. If the Password Status option is Locked, you cannot change the system password. When the system password feature is disabled by a jumper setting, the system password is Disabled, and you cannot change or enter a new system password.

When a system password is not assigned and the password jumper on the system board is in the enabled (default) position, the setting shown for the System Password option is Not Set and the Password Status field is Unlocked. To assign a system password:

Verify that the Password Status option is set to Unlocked.
Highlight the System Password option and press <Enter>.
Type your new system password.

You can use up to 32 characters in your password.

As you press each character key (or the spacebar for a blank space), a placeholder appears in the field.

The password assignment is not case-sensitive. However, certain key combinations are not valid. If you enter one of these combinations, the system beeps. To erase a character when entering your password, press <Backspace> or the left-arrow key.

NOTE: To escape from the field without assigning a system password, press <Enter> to move to another field, or press <Esc> at any time prior to completing step 5.

Press <Enter>.
To confirm your password, type it a second time and press <Enter>.

The setting shown for the System Password changes to Set.

Save and exit the System Setup program and begin using your system.

Using Your System Password to Secure Your System

NOTE: If you have assigned an admin password (see "Using the Admin Password"), the system accepts your admin password as an alternate system password.

When the Password Status option is set to Unlocked, you have the option to leave the password security enabled or to disable the password security.

To leave the password security enabled:

Turn on or reboot your system by pressing <Ctrl><Alt><Del>.
Type your password and press <Enter>.

When the Password Status option is set to Locked whenever you turn on your system or reboot your system by pressing <Ctrl><Alt><Del>, type your password and press <Enter> at the prompt.

After you type the correct system password and press <Enter>, your system operates as usual.

If an incorrect system password is entered, the system displays a message and prompts you to re-enter your password. You have three attempts to enter the correct password. After the third unsuccessful attempt, the system displays an error message showing the number of unsuccessful attempts and that the system has halted and will shut down. This message can alert you to an unauthorized person attempting to use your system.

Even after you shut down and restart the system, the error message continues to be displayed until the correct password is entered.

NOTE: You can use the Password Status option in conjunction with the System Password and Admin Password options to further protect your system from unauthorized changes.

Deleting or Changing an Existing System Password

Enter the System Setup program.
Highlight the System Password option, press <Enter> to access the system password window, and press <Enter> twice to clear the existing system password.

The setting changes to Not Set.

If you want to assign a new system password, perform the steps in "Assigning a System Password."

Using the Admin Password

Assigning a Admin Password

You can assign (or change) an admin password only when the Admin Password option selected is Not Set. To assign a setup password:

Highlight the Admin Password option and press <Enter>.
Type your new admin password.

You can use up to 32 characters in your password.

As you press each character key (or the spacebar for a blank space), a placeholder appears in the field.

NOTE: To escape from the field without assigning a system password, press <Enter> to move to another field, or press <Esc> at any time prior to completing step 5.

Press <Enter>.
To confirm your password, type it a second time and press <Enter>.

The setting shown for the Admin Password changes to Set.

Save and exit the System Setup program and begin using your system.

The next time you enter the System Setup program, the system prompts you for the admin password.

A change to the Admin Password option becomes effective immediately (restarting the system is not required).

Operating With a Admin Password Set

If Admin Password is Set, you must enter the correct admin password before you can modify most of the System Setup options. When you start the System Setup program, the program prompts you to enter a password.

If you do not enter the correct password in three attempts, the system lets you view, but not modify, the System Setup screens—with the following exception: If System Password is not set to Set and is not locked through the Password Status option, you can assign a system password (however, you cannot disable or change an existing system password).

NOTE: You can use the Password Status option in conjunction with the Admin Password option to protect the system password from unauthorized changes.

Deleting or Changing an Existing Admin Password

Enter the System Setup program.
Highlight the Admin Password option, press <Enter> to access the admin password window, and press <Enter> twice to clear the existing admin password.

The setting changes to Not Set.

If you want to assign a new admin password, perform the steps in "Assigning a Admin Password."

Disabling a Forgotten Password
