Handling
fiber-optic
cables
Before
you
use
fiber-optic
cables,
read
the
following
precautions.
Attention:
To
avoid
damage
to
the
fiber-optic
cables,
follow
these
guidelines:
v
Do
not
route
the
cable
along
a
folding
cable-management
arm.
v
When
attaching
to
a
device
on
slide
rails,
leave
enough
slack
in
the
cable
so
that
it
does
not
bend
to
a
radius
of
less
than
38
mm
(1.5
in.)
when
extended
or
become
pinched
when
retracted.
v
Route
the
cable
away
from
places
where
it
can
be
snagged
by
other
devices
in
the
rack
cabinet.
v
Do
not
overtighten
the
cable
straps
or
bend
the
cables
to
a
radius
of
less
than
38
mm
(1.5
in.).
v
Do
not
put
excess
weight
on
the
cable
at
the
connection
point.
Be
sure
that
the
cable
is
well
supported.
CAUTION:
Data
processing
environments
can
contain
equipment
transmitting
on
system
links
with
laser
modules
that
operate
at
greater
than
Class
1
power
levels.
For
this
reason,
never
look
into
the
end
of
an
optical
fiber
cable
or
open
receptacle.
Connecting
your
N3700
storage
system
to
a
network
Each
node
of
your
N3700
storage
system
connects
to
the
network.
If
you
have
an
active-active
(clustered)
system
both
nodes
need
to
connect
to
the
network.
For
information
that
describes
how
to
connect
your
N3700,
refer
to
the
Installation
and
Setup
Instructions
for
your
storage
system.
Connecting
expansion
units
You
can
connect
additional
expansion
units
to
an
N3700.
For
information
that
describes
how
to
connect
your
N3700
storage
system
up
to
a
maximum
of
three
expansion
units,
see
the
Installation
and
Setup
Instructions
for
your
storage
system.
On
all
N3700
storage
systems,
Port
B
is
designated
for
use
in
connections
to
expansion
units.
Note:
The
N3700
only
operates
at
1
Gbps.
Make
sure
that
the
speed
setting
switches
on
the
expansion
units
are
set
to
1Gb.
