10. Install a heat sink on the microprocessor: a. Remove the plastic protective cover from the bottom of the heat sink, if one is present. Attention: 1) Do not set down the heat sink after you remove the plastic cover. 2) Do not touch the thermal grease on the bottom of the heat sink. Touching the thermal grease will contaminate it. If the thermal grease becomes contaminated, contact your service technician. b. Align and place the heat sink on top of the microprocessor. Press firmly on the heat sink. 11. Lower the retention mechanism; then, screw down the captive mounting screw using a #2 Pillips screwdriver. Do not over-tighten the screw. If you are using a torque wrench, tighten the screws to 8,5 to 13 Nm (6.3 to 9.6 foot-pounds). Attention: To help ensure proper cooling and system reliability the air baffle must be correctly positioned and fully seated. 12. Install the air baffle covering microprocessor 1 and microprocessor 4, making sure that the air baffle is positioned and pushed down so that both heat sink captive mounting screws are through the holes in the air baffle. Air baffle Microprocessor 1 and 4 heat sink captive mounting screws 13. If you have other options to install or remove, do so now; otherwise, go to "Completing the installation" on page 62. Installing an I/O expansion card You can add one or two optional I/O expansion cards to your blade server to give the blade server up to four additional network connections for communicating on a network. Each I/O expansion card provides two additional network connections that are routed through switch-module bays 3 and 4 of the BladeCenter unit. If two I/O expansion cards are installed, both expansion cards must be of the same type. Attention: When you add an I/O expansion card, you must make sure that the switch modules in switch-module bays 3 and 4 on the BladeCenter unit both support the I/O expansion card network-interface type. For example, if you add an Ethernet expansion card to your blade server, the modules in switch-module bays 3 and 4 on the BladeCenter unit must both be compatible with the Ethernet expansion card. All other I/O expansion cards that are installed on other blade servers in the BladeCenter unit must also be compatible with these switch modules. In this example, you could then install two Ethernet switch modules, two pass-thru modules, or one Ethernet switch module and one pass-thru module. Because pass-thru modules are compatible with a variety of I/O expansion cards, installing two pass-thru modules would allow use of several different types of compatible I/O expansion cards within the same BladeCenter unit.

Install
a
heat
sink
on
the
microprocessor:
a.
Remove
the
plastic
protective
cover
from
the
bottom
of
the
heat
sink,
if
one
is
present.
Attention:
1)
Do
not
set
down
the
heat
sink
after
you
remove
the
plastic
cover.
2)
Do
not
touch
the
thermal
grease
on
the
bottom
of
the
heat
sink.
Touching
the
thermal
grease
will
contaminate
it.
If
the
thermal
grease
becomes
contaminated,
contact
your
service
technician.
b.
Align
and
place
the
heat
sink
on
top
of
the
microprocessor.
Press
firmly
on
the
heat
sink.
11.
Lower
the
retention
mechanism;
then,
screw
down
the
captive
mounting
screw
using
a
#2
Pillips
screwdriver.
Do
not
over-tighten
the
screw.
If
you
are
using
a
torque
wrench,
tighten
the
screws
to
8,5
to
13
Nm
(6.3
to
9.6
foot-pounds).
Attention:
To
help
ensure
proper
cooling
and
system
reliability
the
air
baffle
must
be
correctly
positioned
and
fully
seated.
12.
Install
the
air
baffle
covering
microprocessor
1
and
microprocessor
4,
making
sure
that
the
air
baffle
is
positioned
and
pushed
down
so
that
both
heat
sink
captive
mounting
screws
are
through
the
holes
in
the
air
baffle.

If
you
have
other
options
to
install
or
remove,
do
so
now;
otherwise,
go
to
“Completing
the
installation”
on
page
62.
Installing
an
I/O
expansion
card
You
can
add
one
or
two
optional
I/O
expansion
cards
to
your
blade
server
to
give
the
blade
server
up
to
four
additional
network
connections
for
communicating
on
a
network.
Each
I/O
expansion
card
provides
two
additional
network
connections
that
are
routed
through
switch-module
bays
3
and
4
of
the
BladeCenter
unit.
If
two
I/O
expansion
cards
are
installed,
both
expansion
cards
must
be
of
the
same
type.
Attention:
When
you
add
an
I/O
expansion
card,
you
must
make
sure
that
the
switch
modules
in
switch-module
bays
3
and
4
on
the
BladeCenter
unit
both
support
the
I/O
expansion
card
network-interface
type.
For
example,
if
you
add
an
Ethernet
expansion
card
to
your
blade
server,
the
modules
in
switch-module
bays
3
and
4
on
the
BladeCenter
unit
must
both
be
compatible
with
the
Ethernet
expansion
card.
All
other
I/O
expansion
cards
that
are
installed
on
other
blade
servers
in
the
BladeCenter
unit
must
also
be
compatible
with
these
switch
modules.
In
this
example,
you
could
then
install
two
Ethernet
switch
modules,
two
pass-thru
modules,
or
one
Ethernet
switch
module
and
one
pass-thru
module.
Because
pass-thru
modules
are
compatible
with
a
variety
of
I/O
expansion
cards,
installing
two
pass-thru
modules
would
allow
use
of
several
different
types
of
compatible
I/O
expansion
cards
within
the
same
BladeCenter
unit.
