Attention:
v Do not set down the heat sink after you remove the plastic cover.
Heat sink Thermal grease
Figure 23. Location of thermal grease on heat sink
v Do not touch the thermal grease on the bottom of the heat sink.
Touching the thermal grease will contaminate it. If the thermal grease on
the microprocessor or heat sink becomes contaminated, it can be
corrected by a service technician.
b. Align and place the heat sink on top of the microprocessor in the retention
bracket, grease side down. Press firmly on the heat sink.
c. Using a screwdriver, secure the heat sink to the retention bracket on the
system board using the two captive mounting screws. Press firmly on the
screws and tighten them, alternating between them. Do not overtighten the
screws. If you are using a torque wrench, tighten the screws to 1.13
newton-/- 0.13 newton-meters (10 inch-/- 1.15
inch-pounds).
10. If you have other options to install or remove, do so now; otherwise, go to
“Completing the installation” on page 52.
Installing an I/O expansion card
You can add an optional I/O expansion card to the blade server to give the blade
server additional network connections for communicating on a network.
Attention: When you add an I/O expansion card, you must make sure that the
switch modules (also known as I/O modules)
2
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 the 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 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.
"If the IDE hard disk drive that is installed in IDE connector 2 is part of a RAID
array, delete this IDE RAID array configuration before removing the hard disk drive.
2. In the BladeCenter unit Type 8677, these modules are referred to as “switch modules”; in the BladeCenter T unit Types 8720 and
8730, these modules are referred to as “I/O modules.” In this document, these modules will be known as switch modules .
