Installing an I/O expansion card

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.
