132 Jumpers and Connectors
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
and UEFI Boot Manager" on page 37". 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.

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.
