Fibre-channel
cabling
Fibre
channel
is
used
to
connect
storage
nodes
to
storage
servers
and
to
connect
storage
servers
to
storage
expansion
units.
KVM
cabling
The
KVM
switch
allows
a
maximum
of
eight
connections.
Use
the
following
guidelines
for
cabling
the
KVM
switch:
v
Use
the
information
on
each
end
of
each
cable
to
create
a
site
map.
v
When
routing
a
KVM
cable
from
a
cabinet
containing
cluster
nodes
to
another
cabinet
containing
the
KVM
switch,
connect
a
C2T-to-KVM
cable
to
the
cluster
nodes
and
use
a
KVM
extension
cable
to
add
sufficient
length
to
reach
the
KVM
switch.
v
Multiple
KVM
switches
can
be
connected
in
series.
Cluster
nodes
can
be
connected
in
series
to
a
single
KVM
switch
port,
but
the
management
node
and
all
the
storage
nodes
each
require
a
separate
KVM
switch
port.
Certain
systems
might
require
a
second
KVM
switch.
Install
the
second
switch
in
the
expansion
cabinet
that
contains
the
additional
storage
nodes.
v
When
using
two
KVM
switches,
connect
Port
A
(the
console
port)
of
switch
2
to
port
8
of
switch
1.
Use
a
KVM
extension
cable
to
make
the
connection
between
the
two
cabinets.
If
more
length
is
needed,
use
two
KVM
extension
cables
linked
together.
Remote
console
manager
cabling
The
remote
console
manager
(RCM)
switch
has
16
ACT
connections
(KVM
over
RJ-45/CAT5)
and
one
KVM
connection
for
the
console.
Use
the
following
guidelines
for
cabling
the
RCM
switch:
v
Use
the
information
on
each
end
of
each
cable
to
create
a
site
map.
v
When
routing
a
CAT5
KVM
cable
from
a
cabinet
containing
cluster
nodes
to
the
cabinet
containing
the
RCM,
use
a
CCO
cable
and
a
CAT5
cable
sufficiently
long
enough
to
reach
the
RCM
switch.
v
Multiple
KVM
switches
can
be
connected
in
series.
v
Up
to
40
cluster
nodes
can
be
connected
in
series
to
each
ACT
port
on
the
RCM.
The
management
node
and
all
the
storage
nodes
can
also
be
daisy-chained,
with
up
to
16
per
ACT
port.
Multiple
RCMs
can
not
be
daisy-chained
together.
The
RCM
can
be
connected
to
an
Ethernet
network
to
allow
for
remote
access
to
the
consoles
of
the
servers
over
the
network.
Local
console
manager
cabling
The
local
console
manager
(LCM)
switch
accepts
the
CAT5
input
from
the
NetBay
Conversion
Options
and
allows
them
to
be
fed
into
your
management
station.
Its
four
CAT5
input
ports
support
four
chains
of
16
servers
per
chain.
The
local
console
manager
(LCM)
switch
also
supports
Cable
Chaining
Technology
(C2T).
Use
the
following
guidelines
for
cabling
the
LCM
switch:
v
Use
the
information
on
each
end
of
each
cable
to
create
a
site
map.
v
When
routing
a
CAT5
KVM
cable
from
a
cabinet
containing
cluster
nodes
to
the
cabinet
containing
the
LCM,
use
a
CCO
cable
and
a
CAT5
cable
sufficiently
long
enough
to
reach
the
LCM
switch.
v
Multiple
KVM
switches
can
be
connected
in
series.
v
Up
to
16
cluster
nodes
can
be
connected
in
series.
