Connecting High-Speed Stacking Cables
SecureStack C3 Installation Guide 3-11
Connecting High-Speed Stacking Cables
The
stack
of
switches
can
be
connected
in
a
ring
or
daisy
chain
topology.
In
a
ring
topology
all
the
switches
are
connected.
The
only
difference
in
the
cable
connections
in
a
daisy
chain
topology
is
that
one
cable
is
not
installed.
Up
to
8
switches
can
be
stacked
together
using
high
‐
speed
stacking
cables.
You
can
add
switches
and
reach
up
to
a
maximum
of
384
Ethernet
ports
per
stack.
The
high
‐
speed
stacking
cables
allow
the
entire
stack
to
operate
with
a
single
IP
address.
The
high
‐
speed
stacking
cables
are
optional
items
and
must
be
ordered
separately.
The
C3G124
‐
24P
and
C3G124
‐
48P
support
three
types
of
SecureStack
stacking
cables:
•
C2CAB
‐
SHORT
cable
to
connect
two
adjacent
switches
in
the
stack.
If
the
stack
is
in
a
configuration
where
the
adjacent
switches
are
too
far
apart
for
the
SHORT
cables,
the
LONG
cable
can
be
used
for
the
connections.
•
C2CAB
‐
LONG
cable
to
connect
from
the
top
switch
to
the
bottom
switch
in
the
stack.
You
need
only
one
C2CAB
‐
LONG
cable
per
stack.
•
C2CAB
‐
5M
cable
to
connect
from
the
top
switch
to
the
bottom
switch
in
the
stack
when
these
two
switches
are
physically
located
in
seperate
mounting
racks
and
require
a
longer
cable
reach.
Figure 3
‐
7
shows
an
example
of
a
four
‐
high
stack
connected
in
a
ring
topology.
All
STACK
DOWN
and
STACK
UP
connectors
are
used
in
the
installation.
The
high
‐
speed
stacking
cable
(1)
connections
are
from
the
STACK
DOWN
connector
(2)
of
one
switch
to
the
STACK
UP
(3)
connector
of
the
next
switch
up
in
the
stack.
A
high
‐
speed
stacking
cable
connection
from
the
STACK
DOWN
(4)
connector
of
the
switch
at
the
top
of
the
stack
to
the
STACK
UP
(5)
connector
at
the
bottom
of
the
stack
completes
the
ring
connection.
In
a
daisy
chain
topology,
the
last
cable
connection
is
not
made.
