NovaScale Blade 2021 Installation and User’s Guide
9. Install a heat sink on the processor:
Attention:
• Do not set down the heat sink after you remove the plastic cover.
• 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 processor or heat sink becomes
contaminated, contact your service technician.
a. Remove the plastic protective cover from the bottom of the heat sink.
b. Align and place the heat sink on top of the processor 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 8.5 to 13 Newton-meters (Nm) (6.3 to 9.6 foot-pounds).
10. If you have other options to install or remove, do so now; otherwise, go to “Completing the
installation” on page 42.
Installing an I/O expansion card
You can add I/O optional expansion cards to your NovaScale Blade Server to give the NovaScale
Blade Server additional connections for communicating on a network.
Attention:
When you add an expansion card, you must make sure that the I/O modules in I/O module
bays 3 and 4 on the NovaScale Blade Chassis unit both support the expansion card network-
interface type. For example, if you add an Ethernet expansion card to your NovaScale Blade
Server, the modules in I/O module bays 3 and 4 on the NovaScale Blade Chassis unit must
both be compatible with the expansion card. All other expansion cards that are installed on
other NovaScale Blade Servers in the NovaScale Blade Chassis unit must also be compatible
with these I/O 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 enable the use of several different types of compatible I/O
expansion cards within the same unit.
