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 .
The password jumper enables these password features or disables them and clears any password(s) currently in use.
1. Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
2. Open the system. See Opening and Closing the System .
3. Remove the jumper plug from the password jumper.
See Figure 6 -1 to locate the password jumper (labeled "PWRD_EN") on the system board.
4. Close the system.
5. Reconnect your system and peripherals to their electrical outlets, 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.
