Verify
that
a
link
exists
by
checking
that
the
port
Link/Activity
LED
is
on
(blinking
green
or
solid
green).
If
the
Link/Activity
LED
is
off,
perform
the
following
steps
until
it
is
on:
a.
Verify
that
the
device
at
the
other
end
of
the
segment
is
ON
and
connected
to
the
segment.
b. If
there
are
separate
fiber
‐
optic
connections
on
the
other
device,
check
the
crossover
of
the
cables.
Swap
the
cable
connections
if
necessary.
c.
Check
that
the
fiber
‐
optic
connection
meets
the
dB
loss
and
cable
specifications
outlined
in
the
Cabling
Guide
for
multimode
cabling.

Connecting Fiber-Optic Cables to LC Ports
This
section
describes
how
to
connect
•
a
1000BASE
‐
SX
multimode
fiber
‐
optic
segment
from
the
network
or
other
devices
to
an
LC
port
connector
of
a
Mini
‐
GBIC
(MGBIC
‐
LC01
or
MGBIC
‐
LC03),
or
•
a
1000BASE
‐
LX
single
‐
mode
fiber
‐
optic
segment
from
the
network
or
other
devices
to
an
LC
port
connector
of
a
Mini
‐
GBIC
(MGBIC
‐
LC09).
Each
fiber
‐
optic
link
consists
of
two
fiber
‐
optic
strands
within
the
cable:
•
Transmit
(TX)
•
Receive
(RX)
The
transmit
strand
from
a
device
port
connects
to
the
receive
port
of
a
fiber
‐
optic
Gigabit
Ethernet
device
at
the
other
end
of
the
segment.
The
receive
strand
of
the
applicable
LC
port
connects
to
the
transmit
port
of
the
fiber
‐
optic
Gigabit
Ethernet
device.
Enterasys
recommends
labeling
fiber
‐
optic
cables
to
indicate
receive
and
transmit
ends.
Many
cables
are
pre
‐
labeled,
providing
matching
labels
or
tapes
at
both
ends
of
each
strand
of
cable.
Warning:
Do not use optical instruments to view laser output. The use of optical
instruments to view laser output increases eye hazard.
Advertencia:
No utilizar instrumentos opticos para ver el laser. El uso de instrumentos
opticos para ver el laser incrementa el riesgo de perdida de la vision.
Warnhinweis:
Benutzen sie keinesfalls optische Hilfmittel, um die Funktion des Lasers zu
überprüfen, es könnte ihr Augenlicht gefährden.
