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 The server supports up to two AMD Opteron microprocessors. If the server comes with one microprocessor, you can install a second microprocessor but it must be the same type and speed as the original microprocessor. v Read the documentation that comes with the microprocessor to determine whether you must update the basic input/output system (BIOS) code for the server. To download the latest level of BIOS code and many other code updates for your server go to http://www.ibm.com/servers/eserver/support/xseries/ index.html, select System x3655 from the Hardware list, and click the Download tab. v (Optional) Obtain an SMP-capable operating system. For a list of supported operating systems and other optional devices, go to http://www.ibm.com/servers/ eserver/serverproven/compat/us. v To order additional microprocessor options, contact your IBM marketing representative or authorized reseller. v The microprocessor speeds are automatically set for this server; therefore, you do not have to set any microprocessor frequency-selection jumpers or switches. v If you have to replace a microprocessor, call for service. v If the thermal-grease protective cover (for example, a plastic cap or tape liner) is removed from the heat sink, do not touch the thermal grease on the bottom of the heat sink or set down the heat sink. v Do not remove the first microprocessor from the system board to install the second microprocessor. See "System-board optional-device connectors" on page 17 for the location of the microprocessor connectors. The following illustration shows how to install the second microprocessor on the system board. Chapter 2. Installing optional devices 51

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
The
server
supports
up
to
two
AMD
Opteron
microprocessors.
If
the
server
comes
with
one
microprocessor,
you
can
install
a
second
microprocessor
but
it
must
be
the
same
type
and
speed
as
the
original
microprocessor.
v
Read
the
documentation
that
comes
with
the
microprocessor
to
determine
whether
you
must
update
the
basic
input/output
system
(BIOS)
code
for
the
server.
To
download
the
latest
level
of
BIOS
code
and
many
other
code
updates
for
your
server
go
to
index.html,
select
System
x3655
from
the
Hardware
list,
and
click
the
Download
tab.
v
(Optional)
Obtain
an
SMP-capable
operating
system.
For
a
list
of
supported
operating
systems
and
other
optional
devices,
go
to
eserver/serverproven/compat/us.
v
To
order
additional
microprocessor
options,
contact
your
IBM
marketing
representative
or
authorized
reseller.
v
The
microprocessor
speeds
are
automatically
set
for
this
server;
therefore,
you
do
not
have
to
set
any
microprocessor
frequency-selection
jumpers
or
switches.
v
If
you
have
to
replace
a
microprocessor,
call
for
service.
v
If
the
thermal-grease
protective
cover
(for
example,
a
plastic
cap
or
tape
liner)
is
removed
from
the
heat
sink,
do
not
touch
the
thermal
grease
on
the
bottom
of
the
heat
sink
or
set
down
the
heat
sink.
v
Do
not
remove
the
first
microprocessor
from
the
system
board
to
install
the
second
microprocessor.
See
“System-board
optional-device
connectors”
on
page
17
for
the
location
of
the
microprocessor
connectors.
The
following
illustration
shows
how
to
install
the
second
microprocessor
on
the
system
board.
