Steps
1.
Turn off the system, including any attached peripherals, and disconnect the system from the
electrical outlet.
2. Open the system.
3. Move the jumper on the system-board jumper from pins 4 and 6 to pins 2 and 4.
4. Close the system.
The existing passwords are not disabled (erased) until the system boots with the jumper on pins 2
and 4. However, before you assign a new system and/or setup password, you must move the jumper
back to pins 4 and 6.
NOTE: If you assign a new system and/or setup password with the jumper on pins 2 and 4, the
system disables the new password(s) the next time it boots.
5. Reconnect the system to its electrical outlet and turn the system on, including any attached
peripherals.
