At power
up
the
LINK
LED
lights
up and
remains
lit
if
it is
connected
to
lOB
aseT
link
that
is
powered
up
This
LED
indicates
that
good
link
has
been
established
If
it
does
not light
check
the
opposite
end
of the
link
to
ensure
that
it is
powered up and
that
the
cable
is
securely installed
If the
LED
still
does
not light switch the transmit
and
receive
pair
at
one
end
of the
link
and
restart
the
system
When
good
link
is
established
the
RCV LED
will
flash
or
remain
lit
to
indicate packet
traffic
on
the link
The
XMT
LED
will
light
when
the
unit transmits data over
the
link
If the
opposite
end
of the link
is
connected
to
hub
the
hub
will
peiform
crossover
function
which
means
that
the transmitter
from
the
unit
goes
to
the receiver of
the
hub
and
the transmitter
from
the
hub
goes
to the
receiver of the unit This configuration
is
correct
however
if
the
unit
connects
to
an
external
media
attachment
unit
MAU
then
the
crossover
function
must
be
performed
in
the
attaching
wires Otherwise
the
two
transmit wires are connected
to
each
other
as are
the
two
receive
wires
