Description
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 Lenovo XClarity Provisioning Manager 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
power-on password in overridden.
Changing the position of this switch does not affect the
administrator password check if an administrator password is set.
