Disabling a Forgotten Password

The computer’s software security features include a supervisor password and a user password, which are dis- cussed in detail in Chapter 4, “Using the System Setup Program,” of the system User’s Guide. A password jumper on the system board enables these password features or disables them and clears any password(s) currently in use.

To disable a forgotten supervisor password or user pass- word, a trained service technician must perform the following steps:

1.Remove the computer covers.

See “Removing the Computer Covers” in Chapter 7 for instructions.

CAUTION: See “Protecting Against Electro- static Discharge” in the safety instructions at the front of this guide.

2.Refer to “Jumpers and Switches—A General Explanation” found earlier in this appendix for jumper information.

Figure C-1 shows the location of the password jumper (labeled “PSWD”) on the system board.

3.Remove the jumper plug from the PSWD jumper.
