Disabling a Forgotten Password

The password jumper on the system board enables the system password features or disables them and clears any password(s) currently in use.

CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. See your Product Information Guide for complete information about safety precautions, working inside the computer, and protecting against electrostatic discharge.

1Turn off the system and attached peripherals, and disconnect the system from the electrical outlet.

2Remove the bezel, if attached. See "Removing the Bezel" on page 46.

3Open the system. See "Opening the System" on page 48.

4Note the cable connections on the SAS RAID daughter card, and then disconnect the cables from the SAS RAID controller daughter card and extend the cables away from the center fan bracket.

5Remove the fans from the center fan bracket. See "Removing and Installing a Fan" on page 53.

6Remove the center fan bracket. See "Removing the Center Fan Bracket" on page 79.

7Remove the password jumper plug.

See Figure 6-1 to locate the password jumper on the system board.

8Replace the center fan bracket (see "Replacing the Center Fan Bracket" on page 79) and replace the fans in the bracket.

9Reconnect the SAS RAID controller daughter card cables.

10Close the system. See "Closing the System" on page 48.

11Reconnect the system to the electrical outlet, and turn on the system.

The existing passwords are not disabled (erased) until the system boots with the password jumper plug removed. However, before you assign a new system and/or setup password, you must install the jumper plug.

NOTE: If you assign a new system and/or setup password with the jumper plug still removed, the system disables the new password(s) the next time it boots.

12Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.

13Open the system.

14Repeat step 4 through step 6.

15Reinstall the password jumper plug in its original position to enable the password protection feature.

16Replace the center fan bracket and fans and reconnect the SAS RAID controller daughter card cables.

17Close the system, reconnect the system to the electrical outlet, and turn on the system.

18Assign a new system and/or setup password.

To assign a new password using the System Setup program, see "Using the System Password" on page 41.
