Disabling A Forgotten Password
The system's software security features include a system password and a setup password. The password
jumper enables these password features or disables them and clears any password(s) currently in use.
CAUTION: See "Protecting Against Electrostatic Discharge" in the safety instructions that came
with the system.
1. Turn off the system, including any attached peripherals, and disconnect the system from the
electrical outlet.
2. Open the system.
3. Remove the jumper plug from the password jumper.
4. Close 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.
5. Turn off the system, including any attached peripherals, and disconnect the system from the
electrical outlet.
