unit.
Your
BladeCenter
unit
comes
with
one
hot-swap
management
module
in
management-module
bay
1.
You
can
add
an
additional
management
module
in
management-module
bay
2.
Only
one
of
these
management
modules
can
be
active
at
one
time,
functioning
as
the
primary
management
module;
a
second
management
module,
if
present,
provides
redundancy.
The
secondary
management
module
remains
inactive
until
it
is
switched
to
act
as
primary.
When
two
management
modules
are
installed
in
the
BladeCenter
unit,
both
management
modules
must
always
have
the
same
level
of
firmware,
at
a
level
that
supports
redundant
management
module
function.
This
helps
ensure
a
smooth
changeover
of
control
from
the
active
management
module
to
the
redundant
management
module.
The
latest
level
of
management-module
firmware
is
available
at
the
IBM
Support
Web
site
at
http://www.ibm.com/pc/support/.
The
management
module
functions
as
a
service
processor
and
a
keyboard/video/mouse
(KVM)
multiplexor
for
all
of
the
blade
servers
installed
in
the
BladeCenter
unit.
It
provides
the
following
external
connections:
keyboard,
mouse,
and
video,
for
use
by
a
local
console,
and
one
RJ-45
connector
for
a
10/100
Mbps
Ethernet
remote
management
connection.
The
service
processor
in
the
management
module
communicates
with
the
service
processor
in
each
blade
server
to
support
features
such
as:
blade
server
power-on
requests,
error
and
event
reporting,
KVM
requests,
and
requests
to
use
the
BladeCenter
shared
media
tray
(diskette
drive,
CD-ROM
drive,
and
USB
port).
You
configure
BladeCenter
components
using
the
management
module,
setting
information
such
as
IP
addresses.
The
management
module
communicates
with
all
components
installed
in
the
BladeCenter
unit,
detecting
their
presence
or
absence,
reporting
their
status,
and
sending
alerts
for
error
conditions
when
required.

Chapter
2.
Configuring
the
management
module
and
BladeCenter
unit
Important:
You
configure
only
the
primary
(active)
management
module.
The
secondary
management
module
receives
the
configuration
and
status
information
automatically
from
the
primary
management
module
when
necessary.
The
configuration
information
in
this
chapter
applies
to
the
primary
management
module,
which
might
be
the
only
management
module
installed
in
the
BladeCenter
unit.
When
the
BladeCenter
unit
is
started
initially,
it
automatically
configures
the
remote
management
port
on
the
active
(primary)
management
module,
so
that
you
can
configure
and
manage
BladeCenter
components.
You
configure
and
manage
BladeCenter
components
remotely
using
the
management-module
Web
interface
or
the
management-module
command-line
interface.
Note:
You
can
also
configure
the
I/O
modules
directly
through
an
external
I/O
module
port,
using
a
Telnet
interface
or
a
Web
browser.
See
the
documentation
that
comes
with
each
I/O
module
for
information.
For
the
management
module
to
communicate
with
the
I/O
modules
in
the
BladeCenter
unit,
you
will
need
to
configure
the
IP
addresses
for
the
following
internal
and
external
ports:
v
The
IP
address
for
the
external
Ethernet
(remote
management)
port
on
the
management
module
(see
the
information
beginning
on
page
30
for
instructions).
The
initial
automatic
configuration
of
the
management
module
enables
the
network
management
station
to
connect
to
the
management
module
to
configure
the
port
completely
and
to
configure
the
rest
of
the
BladeCenter
unit.
v
The
IP
address
for
the
internal
Ethernet
port
on
the
management
module
(see
the
information
beginning
on
page
30
for
instructions)
to
support
communication
with
the
I/O
modules.
v
The
IP
address
for
the
management
port
on
each
I/O
module
(see
the
information
beginning
on
page
25
for
instructions)
for
communication
with
the
management
module.
You
configure
this
port
by
configuring
the
IP
address
for
the
I/O
module.
Note:
Some
types
of
I/O
modules,
such
as
a
pass-thru
module,
have
no
management
port.
To
communicate
with
the
blade
servers
for
functions
such
as
deploying
an
operating
system
or
application
program,
you
also
will
need
to
configure
at
least
one
external
(in-band)
port
on
an
Ethernet
I/O
module
installed
in
I/O
module
bay
1
or
2.
See
the
Installation
and
User’s
Guide
for
your
BladeCenter
unit
for
general
information
about
configuring
the
external
ports
on
Ethernet
I/O
modules.
Note:
If
a
pass-thru
module
is
installed
in
I/O-module
bay
1
or
2
(instead
of
an
Ethernet
I/O
module),
you
will
need
to
configure
the
network
switch
that
the
pass-thru
module
is
connected
to;
see
the
documentation
that
comes
with
the
network
switch
for
instructions.
The
management
module
supports
the
following
Web

for
remote

you
use
must

BladeCenter
Management
Module:
User’s
Guide
Communicating
with
the
IBM
Director
software
The
IBM
Director
program
is
a
system-management
product
that
comes
with
the
BladeCenter
unit.
The
IBM
Director
software
communicates
with
the
BladeCenter
unit
through
the
Ethernet
port
on
the
active
management
module.
Note:
See
the
IBM
Support
Web
site
at
http://www.ibm.com/pc/support/
for
the
version
of
IBM
Director
software
that
you
can
use
to
manage
redundant
management
modules.
To
communicate
with
the
BladeCenter
unit,
the
IBM
Director
software
needs
a
managed
object
(in
the
Group
Contents
pane
of
the
IBM
Director
Management
Console
main
window)
that
represents
the
BladeCenter
unit.
If
the
BladeCenter
management
module
IP
address
is
known,
the
network
administrator
can
create
an
IBM
Director
managed
object
for
the
unit.
If
the
IP
address
is
not
known,
the
IBM
Director
software
can
automatically
discover
the
BladeCenter
unit
(out-of-band,
using
the
Ethernet
port
on
the
BladeCenter
management
module)
and
create
a
managed
object
for
the
unit.
For
the
IBM
Director
software
to
discover
the
BladeCenter
unit,
your
network
must
initially
provide
connectivity
from
the
IBM
Director
server
to
the
BladeCenter
management-module
Ethernet
port.
To
establish
connectivity,
the
management
module
attempts
to
use
DHCP
to
acquire
its
initial
IP
address
for
the
Ethernet
port.
If
the
DHCP
request
fails,
the
management
module
uses
the
static
IP
address
assigned
to
it.
Therefore,
the
DHCP
server
(if
used)
must
be
on
the
management
LAN
for
your
BladeCenter
unit.
Notes:
1.
All
management
modules
are
preconfigured
with
the
same
static
IP
address.
You
can
use
the
management
module
Web
interface
to
assign
a
new
static
IP
address
for
each
BladeCenter
unit.
If
DHCP
is
not
used
and
you
do
not
assign
a
new
static
IP
address
for
each
BladeCenter
