Installing Previously-Configured Systems in a Stack
If
member
units
in
a
stack
have
been
previous
members
of
a
different
stack,
you
may
need
to
configure
the
renumbering
of
the
stack
as
follows:
1.
Stack
the
units
in
the
method
desired,
and
connect
the
stack
cables.
2.
Power
up
only
the
unit
you
wish
to
be
manager.
3.
Once
the
management
unit
is
powered
up,
log
into
the
CLI,
and
use
the
show
switch
command
as
described
in
to
display
stacking
information.
4.
Clear
any
switches
which
are
listed
as
“unassigned”
using
the
clear
switch
member
command
as
described
in
12.
5.
Power
up
the
member
of
the
stack
you
wish
to
become
unit
2.
Once
the
second
unit
is
fully
powered,
the
COM
session
of
the
CLI
will
state
that
a
new
CPU
was
added.
6.
Use
the
show
switch
command
to
redisplay
stacking
information.
a.
If
the
new
member
displays
as
unit
2,
you
can
proceed
to
repeat
this
step
with
the
next
unit.
b. If
the
new
member
displays
a
different
unit
number,
you
must:
(1) Renumber
the
stack
using
the
set
switch
renumber
command
as
described
in
then
(2) Clear
the
original
unit
number
using
the
clear
switch
member
command.
7.
Repeat
Step
6
until
all
members
have
been
renumbered
in
the
order
you
desire.
8.
After
the
stack
has
been
reconfigured,
you
can
use
the
show
switch
unit
command
to
physically
confirm
the
identity
of
each
unit.
When
you
enter
the
command
with
a
unit
number,
the
MGR
LED
of
the
specified
switch
will
blink
for
10
seconds.
The
normal
state
of
this
LED
is
off
for
member
units
and
steady
green
for
the
manager
unit.
Adding a New Unit to an Existing Stack
Use
the
following
procedure
for
installing
a
new
unit
to
an
existing
stack
configuration.
This
procedure
assumes
that
the
new
unit
being
added
has
a
clean
configuration
from
manufacturing
and
is
running
the
same
firmware
image
version
as
other
units
in
the
stack.
1.
Ensure
that
power
is
off
on
the
new
unit
being
installed.
2.
Use
one
of
the
following
methods
to
complete
stack
cable
connections:
–
If
the
running
stack
uses
a
daisy
chain
topology,
make
the
stack
cable
connections
from
the
bottom
of
the
stack
to
the
new
unit
(that
is,
STACK
DOWN
port
from
the
bottom
unit
of
the
running
stack
to
the
STACK
UP
port
on
the
new
unit).
–
If
the
running
stack
uses
a
ring
stack
topology,
break
the
ring
and
make
the
stack
cable
connections
to
the
new
unit
to
close
the
ring.
3.
Apply
power
to
the
new
unit.
