To
install
the
DIMMs,
repeat
the
following
steps
for
each
DIMM
that
you
install:
a.
Turn
the
DIMM
so
that
the
DIMM
keys
align
correctly
with
the
connector
on
the
system
board.
Attention:
To
avoid
breaking
the
retaining
clips
or
damaging
the
DIMM
connectors,
handle
the
clips
gently.
b.
Make
sure
that
the
small
tabs
on
the
retaining
clips
are
in
the
notches
on
the
DIMM.
If
there
is
a
gap
between
the
DIMM
and
the
retaining
clips,
the
DIMM
has
not
been
correctly
installed.
Press
the
DIMM
firmly
into
the
connector,
and
then
press
the
retaining
clips
toward
the
DIMM
until
the
tabs
are
fully
seated.
When
the
DIMM
is
correctly
installed,
the
retaining
clips
are
parallel
to
the
sides
of
the
DIMM.
Important:
If
there
is
a
gap
between
the
DIMM
and
the
retaining
clips,
the
DIMM
has
not
been
correctly
installed.
In
this
case,
open
the
retaining
clips
and
remove
the
DIMM;
then,
reinsert
the
DIMM.

Replace
the
DIMM
air
baffle,
if
one
was
removed
from
the
blade
server
in
order
to
install
DIMMs.
If
you
have
other
options
to
install
or
remove,
do
so
now;
otherwise,
go
to
“Completing
the
installation”
on
page
34.
If
memory
is
installed
in
the
Memory
and
I/O
Expansion
Blade,
you
can
configure
it
to
provide
memory
mirroring
by
using
the
Configuration/Setup
Utility
program.
See
Advanced
Setup
→
Memory
Settings
under
“Configuration/Setup
Utility
menu
choices”
on
page

for
more
information.
Installing
an
additional
microprocessor
The
following
notes
describe
the
type
of
microprocessor
that
the
server
supports
and
other
information
that
you
must
consider
when
installing
a
microprocessor:
v
You
cannot
remove
the
single
microprocessor
and
replace
it
with
a
different
type
of
microprocessor
of
greater
or
lesser
speed.
v
If
you
install
a
second
microprocessor,
you
must
install
the
same
microprocessor
type
and
speed
as
the
first
microprocessor.
v
Some
models
support
dual-core
processors
and
quad-core
processors.
Do
not
mix
dual-core
processors
and
quad-core
processors
in
the
same
system.
Install
all
dual-core
or
all
quad-core
processors
in
the
server.
v
Always
install
microprocessors
that
have
the
same
cache
size
and
type,
the
same
clock
speed,
and
identical
internal
and
external
clock
frequencies
(including
system
bus
speed).
v
Make
sure
that
the
microprocessor
with
the
lowest
feature
set
is
the
startup
(bootstrap)
microprocessor,
which
is
installed
in
the
microprocessor
1
socket
(U6).
v
For
a
list
of
microprocessors
that
the
blade
server
supports,
seehttp://www.ibm.com/servers/eserver/serverproven/compat/us/.
v
Before
installing
a
new
microprocessor,
download
and
install
the
most
current
level
of
BIOS
code
from
http://www.ibm.com/systems/support/.
v
The
microprocessors
terminate
themselves;
therefore,
no
terminator
card
is
required
if
microprocessor
socket
2
(U7)
is
empty.
However,
for
proper
airflow,
this
socket
must
contain
a
microprocessor
heat-sink
filler,
sometimes
called
a
microprocessor
baffle.
v
The
microprocessor
speeds
are
automatically
set
for
this
server;
therefore,
you
do
not
have
to
set
any
microprocessor
frequency-selection
jumpers
or
switches.
