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.

If
a
link
is
not
established,
contact
Enterasys Networks.

Repeat
all
steps
above
until
all
connections
have
been
made.
Installing an Optional SFP
This
section
describes
how
to
install
an
SFP
optical
transceiver
into
combo
SFP
ports
(11
and
12)
on
the
D2G124
‐
12
or
D2G124
‐
12P
unit
It
is
recommended
that
the
options
be
installed
first
in
a
new
installation.
Notes:
Each combo SFP port on the D2G124-12 and D2G124-12P supports the installation of Mini-
GBICs for 1000Base-SX, 1000Base-LX, or 100Base-FX SFP transceivers.
Each combo SFP port in use on these units eliminates the availability of one RJ45 port. In other
words, only twelve ports can be active at any given time on components equipped with a
combination of RJ45 and SFP interfaces. When an SFP transceiver (Mini-GBIC) SFP port 11
establishes a link, RJ45 port 11 is disabled. When an SFP transceiver (Mini-GBIC) in SFP port 12
establishes a link, RJ45 port 12 is disabled.
