Changing the position of this jumper
bypasses the power-on password
check if the jumper has been moved
since the server was last powered
on. You do not need to move the
jumper back to the default position
after the password is overridden.
The default position is a jumper on
pins 2 and 3.
Changing the position of this jumper
does not affect the administrator
password check if an administrator
password is set.
See "Power-on password" on page
48 for additional information on the
power-on password.
