Disabling a Forgotten Password
The system's software security features include a system password and a setup password, which are discussed
in detail in "Using the System Setup Program" on page 23. The password jumper enables these password
features or disables them and clears any password(s) currently in use.
NOTICE: See "Protecting Against Electrostatic Discharge" in the safety instructions in your Product Information
Guide.

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

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.
