Removing and installing management modules The BladeCenter T unit comes with one hot-swap management module in management-module bay 1. You can add a second management module in management-module bay 2. Note: Only one management module is active; the second management module, if present, provides redundancy. Release button Management module Release latch Serial port MAC address The management module functions as a service processor for the multiple blade servers. The management module configures the BladeCenter T unit and modules, configuring information such as switch module IP addresses. The management module also performs USB-to-PS/2 conversions for the system keyboard and mouse and can send the VGA signal stream to a remote console for viewing. See "Management module controls and indicators" on page 10 for information about the controls and indicators. The service processor in the management module communicates with the service processor in each blade server for functions such as: v Blade server power-on requests v Blade server error and event reporting v Blade server requests for keyboard, mouse, and video v Blade server requests for CD-ROM drive and USB ports The management module also communicates with the I/O modules, power modules, blower modules, and blade servers to detect presence or absence and any error conditions, sending alerts when required. Use the instructions in this section to remove or install a management module at the front of the BladeCenter T unit. Chapter 4. Setting up the BladeCenter T hardware 51

Removing
and
installing
management
modules
The
BladeCenter
T
unit
comes
with
one
hot-swap
management
module
in
management-module
bay
1.
You
can
add
a
second
management
module
in
management-module
bay
2.
Note:
Only
one
management
module
is
active;
the
second
management
module,
if
present,
provides
redundancy.

The
management
module
functions
as
a
service
processor
for
the
multiple
blade
servers.
The
management
module
configures
the
BladeCenter
T
unit
and
modules,
configuring
information
such
as
switch
module
IP
addresses.
The
management
module
also
performs
USB-to-PS/2
conversions
for
the
system
keyboard
and
mouse
and
can
send
the
VGA
signal
stream
to
a
remote
console
for
viewing.
See
“Management
module
controls
and
indicators”
on
page
10
for
information
about
the
controls
and
indicators.
The
service
processor
in
the
management
module
communicates
with
the
service
processor
in
each
blade
server
for
functions
such
as:
v
Blade
server
power-on
requests
v
Blade
server
error
and
event
reporting
v
Blade
server
requests
for
keyboard,
mouse,
and
video
v
Blade
server
requests
for
CD-ROM
drive
and
USB
ports
The
management
module
also
communicates
with
the
I/O
modules,
power
modules,
blower
modules,
and
blade
servers
to
detect
presence
or
absence
and
any
error
conditions,
sending
alerts
when
required.
