NMI (nonmaskable
interrupt) switch (SW1)
Off NMI button on rear of server pressed: NMI issued
Power-on password
switch (SW2-1)
Off Power-on password override. Changing the position
of this switch bypasses the power-on password
check the next time the server is turned on and
starts the Configuration/Setup Utility program so
that you can change or delete the power-on
password. You do not have to move the switch
back to the default position after the password is
overridden.
Changing the position of this switch does not affect
the administrator password check if an
administrator password is set.
See the User’s Guide on the IBM System x
Documentation CD for additional information about
the power-on password.
