on
4G4202
‐
60
as
shown
in
4G4202
‐

b. Verify
that
the
cabling
being
used
is
Category
5
UTP
with
an
impedance
between
85
and
111 ohms.
If
the
port
is
to
operate
at
100 Mbps,
category 5
cabling
must
be
used.
c.
Verify
that
the
device
at
the
other
end
of
the
twisted
pair
segment
is

connectors
on
the
twisted
pair
segment
have

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
to

Refer
to
Figure 3
‐
