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.

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.
