Installing
a
microprocessor
and
heat
sink
Read
the
documentation
that
comes
with
the
microprocessor
to
determine
whether
you
must
update
the
firmware.
Important:
Some
cluster
solutions
require
specific
code
levels
or
coordinated
code
updates.
If
the
device
is
part
of
a
cluster
solution,
verify
that
the
latest
level
of
code
is
supported
for
the
cluster
solution
before
you
update
the
code.
To
download
the
most
current
level
of
server
firmware,
complete
the
following
steps:
1.
Go
to:
2.
Enter
your
product
number
(machine
type
and
model
number)
or
select
Servers
and
Storage
from
the
Select
your
product
list.
3.
From
Family
list,
select
ThinkServer

and
click
Continue.
4.
Click

to
download
firmware
updates.
Important:
v
A
startup
(boot)
microprocessor
must
always
be
installed
in
microprocessor
connector
1
on
the
system
board.
v
To
ensure
correct
server
operation,
make
sure
that
you
use
microprocessors
that
are
compatible
and
you
have
installed
an
additional
DIMM
for
microprocessor
2.
Compatible
microprocessors
must
have
the
same
QuickPath
Interconnect
(QPI)
link
speed,
integrated
memory
controller
frequency,
core
frequency,
power
segment,
cache
size,
and
type.
v
Microprocessors
with
different
stepping
levels
are
supported
in
this
server.
If
you
install
microprocessors
with
different
stepping
levels,
it
does
not
matter
which
microprocessor
is
installed
in
microprocessor
connector
1
or
connector
2.
v
If
you
are
installing
a
microprocessor
that
has
been
removed,
make
sure
that
it
is
paired
with
its
original
heat
sink
or
a
new
replacement
heat
sink.
Do
not
reuse
a
heat
sink
from
another
microprocessor;
the
thermal
grease
distribution
might
be
different
and
might
affect
conductivity.
v
If
you
are
installing
a
new
heat
sink,
remove
the
protective
backing
from
the
thermal
material
that
is
on
the
underside
of
the
new
heat
sink.
v
If
you
are
installing
a
new
heat-sink
assembly
that
did
not
come
with
thermal
grease,
see
for
instructions
for
applying
thermal
grease;
then,
continue
with
step
of
this
procedure.
v
If
you
are
installing
a
heat
sink
that
has
contaminated
thermal
grease,
see
for
instructions
for
replacing
the
thermal
grease;
then,
continue
with
step
of
this
procedure.
To
install
a
new
or
replacement
microprocessor,
complete
the
following
steps.
The
following
illustration
shows
how
to
install
a
microprocessor
on
the
system
board.
1.
Touch
the
static-protective
package
that
contains
the
microprocessor
to
any
unpainted
metal
surface
on
the
server.
Then,
remove
the
microprocessor
from
the
package.
2.
Rotate
the
microprocessor
release
lever
on
the
socket
from
its
closed
and
locked
position
until
it
stops
in
the
fully
open
position.
