First,
insert
the
SFP
into
the
port,
and
then
insert
a
fiber-optic
cable
into
the
SFP.
The
other
end
of
the
fiber-optic
cable
connects
to
an
external
device.
Note
that
SFPs
are
laser
products.
Statement
3
CAUTION:
When
laser
products
(such
as
CD-ROMs,
DVD
drives,
fiber
optic
devices,
or
transmitters)
are
installed,
note
the
following:
v
Do
not
remove
the
covers.
Removing
the
covers
of
the
laser
product
could
result
in
exposure
to
hazardous
laser
radiation.
There
are
no
serviceable
parts
inside
the
device.
v
Use
of
controls
or
adjustments
or
performance
of
procedures
other
than
those
specified
herein
might
result
in
hazardous
radiation
exposure.
Danger
Some
laser
products
contain
an
embedded
Class
3A
or
Class
3B
laser
diode.
Note
the
following.
Laser
radiation
when
open.
Do
not
stare
into
the
beam,
do
not
view
directly
with
optical
instruments,
and
avoid
direct
exposure
to
the
beam.
Types
of
interface
ports
The
following
sections
briefly
discuss
the
types
of
interface
ports.
Host
ports
DS4300
controller
host
ports
are
used
for
data
transfer
between
hosts
(servers)
and
the
RAID
controllers
in
the
DS4300
Storage
Subsystem.
Each
controller
has
two
independent
host
ports
in
a
switched
(not
a
hub)
implementation.
To
ensure
redundancy,
you
must
connect
each
host
to
both
controllers
through
the
appropriate
port.
The
DS4300
with
dual
controllers
(model
60X/U)
support
a
maximum
of
two
hosts
redundantly
directly
connected
to
it.
To
support
more
host
connections,
one
can
connected
the
DS4300
host
ports
and
the
servers
to
the
FC
switches
in
a
SAN.
The
DS4300
single
controller
supports
a
maximum
of
two
hosts
non-redundantly
connected
to
it.
