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. See "Opening the System" on page 52.
3
Remove the jumper plug from the password jumper.
See
Figure 5-1
to locate the password jumper (labeled “PWRD_EN”) on
the system board.
4
Close the system. See "Closing the System" on page 53.
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.
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.
6
