are
defined
through
the
primary
server.
If
you
bypass
the
16-way
configuration
during
start
up
or

a
stand
alone
configuration,

password
to
complete
the
system
startup,
and

have
access
to
the
full

password
is
intended
to
be

by
a
system
administrator;
it
limits
access
to
the
full

Utility
menu.
If
you
set
only

complete
the
system
startup,
but
you
must
type
the
administrator
password
to
access
the
Configuration/Setup
Utility
menu.
If
you
set
a
power-on
password
for
a
user
and
an
administrator
password
for
a
system
administrator,
you
can
type
either
password
to
complete
the
system
startup.
A
system
administrator
who
types
the
administrator
password
has
access
to
the
full
Configuration/Setup
Utility
menu;
the
system
administrator
can
give
the
user
authority
to
set,
change,
and
delete
the
power-on
password.
A
user
who
types
the
power-on
password
has
access
to
only
the
limited
Configuration/Setup
Utility
menu;
the

change,
and
delete
the
power-on
password,
if
the

administrator
has
given
the
user
that
authority.
