sequence.
Each

Installing
an
I/O-expansion
card
If
I/O-expansion
is
supported
by
the
BladeCenter
unit
in
which
the
blade
server
is
installed,
you
can
add
an
I/O-expansion
card
to
the
blade
server.
I/O-expansion
cards
give
the
blade
server
additional
connections
for
communicating
on
a
network.
Your
blade
server
supports
the
installation
of
one
I/O-expansion
card
of
small-form-factor
or
standard-form-factor
design.
You
cannot
install
both
sizes
of
an
I/O-expansion
card
in
a
blade
server
at
the
same
time.
You
can
install
a
small-form-factor
expansion
card
in
addition
to
two
SAS
hard
disk
drives,
or
you
can
install
a
standard-form-factor
I/O-expansion
card
into
a
blade
server
with
one
SAS
hard
disk
drive.
The
blade
server
supports
a
number
of
LAN
daughter
cards,
such
as:
v
Gigabit
Ethernet
expansion
card
v
Fibre
Channel
expansion
card
v
Myrinet
expansion
card
See
the
ServerProven
list
at
http://www.ibm.com/servers/eserver/serverproven/
for
a
list
of
available
I/O-expansion
cards
and
their
form-factor
types.
When
you
add
an
I/O-expansion
card,
you
must
make
sure
that
the
I/O-modules
it
is
mapped
to
both
support
the
expansion
card
network-interface
type.
These
I/O-modules
are
typically
installed
in
I/O-module
bays
3
and
4
on
the
BladeCenter
unit.
For
example,
if
you
add
an
Ethernet
expansion
card
to
a
blade
server
installed
in
a
Type
8677
BladeCenter
unit,
the
I/O-modules
in
I/O-module
bays
3
and
4
on
the
BladeCenter
unit
must
both
be
compatible
with
the
expansion
card.
All
other
expansion
cards
that
are
installed
on
other
blade
servers
in
the
BladeCenter
unit
must
also
be
compatible
with
these
I/O-modules.
In
this
example,
you
could
then
install
two
Ethernet
switch
modules,
two
pass-thru
modules,
or
one
Ethernet
switch
module
and
one
pass-thru
module.
Because
pass-thru
modules
are
compatible
with
a
variety
of
I/O-expansion
cards,
installing
two
pass-thru
modules
would
enable
the
use
of
several
different
types
of
compatible
I/O-expansion
cards
on
blade
servers
within
the
same
BladeCenter
unit.
