Dell PowerEdge 7150 - Manual (Page 22)

The Security Screen also allows you to enable and configure the Secure Mode option. When the system is in Secure Mode, most input and output devices are disabled
until you enter the user password. You can modify the Security Screen settings to activate Secure Mode after a period of inactivity, at system boot, after a period of
system inactivity, or by pressing a key sequence that you define using a Security Screen option.
Boot Screen
The Boot Screen options determine the boot search order for devices connected to the system. Available options include the diskette drive, hard-disk drives, CD-
ROM drive, and removable devices. This screen also allows you to bypass certain system tests during system startup, and select the relative order of the primary and
secondary IDE devices.
System Management Screen
You can select the Console Redirection submenu from the System Management screen. Use this submenu to enable and configure an I/O port to support console
redirection.
Exit Screen
After you press <Esc> to exit the system setup program, the Exit screen displays the following choices:
l Exit Saving Changes — Use this option if you wish to implement changes made to the system setup options.
l Exit Discarding Changes — Use this option to return the system setup options to their previous settings.
l Load Setup Defaults — This option allows you to return all system setup options to their original default settings.
l Save Customer Defaults — This option lets you save the current system setup option values in a file to preserve a particular system configuration.
l Load Custom Defaults — This option loads a set of option settings previously saved using the Save Customer Defaults option.
l Discard Changes — This option allows you to return the system setup options to their previous settings, without exiting the system setup program.
Using the Password Features
Your Dell system is shipped to you without the password features enabled. If system security is a concern, you should operate your system only with password
protection. The user password protects against unauthorized access to your system; the supervisor password protects against unauthorized changes to the system
setup program.
Assigning a User Password
When no user password is assigned and the password jumper on the I/O riser board is in the enabled position (its default), the setting shown for the User Password
option is Not Installed.
From the Security screen, highlight the Set User Password category and press <Enter> to display a dialog box in which you can enter a user password. Keep the
following tips in mind when setting your password:
l You can use up to seven alphanumeric characters in your password (passwords are not case sensitive).
l As you press each character key (or the Spacebar for a blank space), a placeholder appears in the field.
l To erase a character when entering your password, press <Backspace>.
l To escape from the field without assigning a user password, press <Esc>.
l Password protection does not take effect until you reboot the system by turning the system off and then on again.
Deleting or Changing an Existing User Password
To delete the user password, enter the system setup program, select Set User Password from the Security Menu, and press <Enter> to display the Set Password
dialog box. Enter the current user password, press <Enter>, leave the password field blank, then press <Enter> again.
To change an existing user password, enter the system setup program, select the Set User Password category from the Security screen, and enter the current user
password. Then assign a new password as described in "
Assigning a User Password ."
NOTE: See the section "Using the Password Features" for instructions on assigning a password and using or changing an existing password. See the section,
"Disabling a Forgotten Password" for instructions on disabling a forgotten password.
NOTICE: If you leave your system running and unattended without having a user password assigned, or if you leave your computer chassis unlocked so that
someone can disable the password by changing a jumper setting on the I/O riser board, anyone can access the data stored on the system hard-disk drives.
