Verify
that
a
link
exists
by
checking
that
the
Link/Activity
LED
is
ON
(solid
green
or
blinking
green).

If
the
Link/Activity
LED
is
OFF,
perform
the
following
steps
until
it
is
on:
a.
Verify
that
the
cabling
being
used
is
Category 5
or
better
with
an
impedance
between
85
and
111 ohms
with
a
maximum
length
of
100
meters
(328
feet).
b. Verify
that
the
device
at
the
other
end
of
the
twisted
pair
segment
is
on
and
properly
connected
to
the
segment.
c.
Verify
that
the
RJ45
connectors
on
the
twisted
pair
segment
have
the
proper
pinouts
and
check
the
cable
for
continuity.
Typically,
a
crossover
cable
is
used
between
hub
devices.
A
straight
‐
through
cable
is
used
to
connect
between
switches
or
hub
devices
and
an
end
user
(computer).
Refer

that
the
twisted
pair
connection
meets
the
dB
loss
and
cable
specifications
outlined
in
the
