Administrator
password
The
administrator
password
is
used
to
restrict
access
to
the
Configuration/Setup
Utility
program.
If
the
administrator
password
is
activated,
and
you
do
not
enter
the
administrator
password,
the
configuration
can
be
viewed
but
not
changed.
Note:
Types
2179
and
6643
have
Enhanced
Security
Mode.
If
Enhanced
Security
mode
is
enabled
and
there
is
no
password
given,
the
computer
will
act
as
if
Enhanced
Security
is
disabled.
If
Enhanced
Security
is
Enabled
and
an
administrator
password
is
given,
the

must
be

the
computer.
If
the
administrator

is
lost
or
forgotten,
the

board
in
the

in
order
to
regain

Operating
system

is
very
similar
to
a

password
and
denies
access
to
the
computer
by
an
unauthorized
user
when
the
password
is
activated.
The
computer
is
unusable
until
the
password
is
entered
and
recognized
by
the
computer.

Each

has
a
unique

After
you

the
