release
latch
to
the
fully-open
position.
8.
Open
the
microprocessor
bracket
frame.
9.
Using
the
vacuum
tool
that
comes
with
the
replacement
microprocessor,
carefully
remove
the
microprocessor.
10.
If
you
are
instructed
to
return
the
microprocessor,
follow
all
packaging
instructions,
and
use
any
packaging
materials
for
shipping
that
are
supplied
to
you.
Installing
a
microprocessor
For
information
about
the
type
of
microprocessor
that
the
server
supports
and
other
information
that
you
must
consider
when
installing
a
microprocessor,
see
the
User’s
Guide
on
the
IBM
System
x
Documentation
CD.
Read
the
documentation
that
comes
with
the
microprocessor
to
determine
whether
you
must
update
the
basic
input/output
system
(BIOS)
code.
To
download
the
most
current
level
of
BIOS
code,
go
to
http://www.ibm.com/servers/eserver/support/
xseries/index.html,
select
System
x3650
from
the
Hardware
list,
and
click
the
Download
tab.
Attention:
v
A
startup
(boot)
microprocessor
must
always
be
installed
in
microprocessor
connector
1
on
the
system
board.
v
To
ensure
correct
server
operation
when
you
install
an
additional
microprocessor,
use
microprocessors
that
have
the
same
cache
size
and
type,
and
the
same
clock
speed.
Microprocessor
internal
and
external
clock
frequencies
must
be
identical.
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.
To
install
a
new
or
replacement
microprocessor,
complete
the
following
steps.
The
following
illustration
shows
how
to
install
microprocessor
2
on
the
system
board.
A
VRM
is
required
only
if
microprocessor
2
is
installed.
