Complete
the
following
steps
to
install
a
pair
of
DIMMs:
1.
Read
the
safety
information
beginning
on
page
v
and
“Installation
guidelines”
on
page
11.
2.
Turn
off
the
server
and
peripheral
devices,
and
disconnect
the
power
cords
and
all
external
cables.
Remove
the
cover
and
air-baffle
assembly.
Attention:
To
avoid
breaking
the
retaining
clips
or
damaging
the
DIMM
connectors,
open
and
close
the
clips
gently.
3.
Open
the
retaining
clip
on
each
end
of
the
DIMM
connector.
4.
Touch
the
static-protective
package
containing
the
DIMM
to
any
unpainted
metal
surface
on
the
server.
Then,
remove
the
DIMM
from
the
package.
5.
Turn
the
DIMM
so
that
the
DIMM
keys
align
correctly
with
the
slot.
6.
Insert
the
DIMM
into
the
connector.
7.
Repeat
steps
1
through
6
for
the
second
DIMM;
then,
continue
to
step
8.
If
you
are
replacing
a
single
DIMM,
continue
to
step
8.
8.
If
you
have
other
options
to
install
or
remove,
do
so
now.
9.
Replace
the
air-baffle
assembly
and
cover.
Go
to
“Completing
the
installation”
on
page
46.
Installing
a
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
For
a
list
of
supported
options
for
the
server,
go
to
http://www.ibm.com/servers/eserver/serverproven/compat/us.
v
The
server
supports
Intel
Xeon
™
2.8
GHz
or
higher
microprocessors
in
each
socket.
If
you
are
installing
two
microprocessors,
they
must
be
the
same
cache
size
and
type,
and
the
same
clock
speed.
v
Read
the
documentation
that
comes
with
the
microprocessor
to
determine
whether
you
must
update
the
basic
input/output
system
(BIOS)
code
in
the
server.
To
download
the
most
current
level
of
BIOS
code
for
the
server,
go
to
http://www.ibm.com/support/.
v
Obtain
an
SMP-capable
operating
system.
For
a
list
of
supported
operating
systems,
go
to
http://www.ibm.com/us/compat/.
v
You
can
use
the
Configuration/Setup
Utility
program
to
determine
the
specific
type
of
microprocessor
in
the
server.
v
If
the
thermal-grease
protective
cover
(for
example,
a
plastic
cap
or
tape
liner)
is
removed
from
the
heat
sink
or
fan
sink,
do
not
touch
the
thermal
grease
on
the
bottom
of
the
heat
sink
or
fan
sink
or
set
down
the
heat
sink
or
fan
sink.
Note:
Removing
the
heat
sink
or
fan
sink
from
the
microprocessor
destroys
the
even
distribution
of
the
thermal
grease
and
requires
replacing
the
thermal
grease.
Setting
down
the
heat
sink
or
fan
sink
on
any
surface
when
the
thermal-grease
protective
cover
is
removed
will
contaminate
the
thermal
grease.
If
the
thermal
grease
becomes
contaminated
with
particles,
it
must
be
replaced.
For
information
about
replacing
contaminated
thermal
grease
on
the
heat
sink,
contact
IBM
Service.
For
support
phone
numbers,
go
to
http://www.ibm.com/planetwide/,
or
in
the
U.S.
and
Canada,
call
1-800-IBM-SERV
(1-800-426-7378).
Have
the
following
information
ready
when
you
call:
–
