t
o the expansion-bay bracket:
a
Position the RAC card on the expansion-bay bracket so that the plastic standoff at the back of the
bracket inserts into the notch on the edge of the RAC card.
bCarefully press the
back
end
o
f the card onto the
two
plastic standoffs until the clips on the
standoffs snap over the card edges. See
Figure3-22
.
7Attach the ribbon cables to the RAC card connectors (see Figure3-22) and to the RAC connectors
on the system board (see
Figure 6- 2
):
NOTICE: Be careful when attaching cables to the system board that you do not damage the surrounding system
board components. Be particularly careful that you do not push or bend the system capacitors near the connectors.
aConnect one cable to connector 1 on the RAC card and to RAC_CONN1 on the system board.
bConnect the second cable to connector 2 on the RAC card and to RAC_CONN2 on the system
board.
8Reinstall the cooling shroud
. See "Installing the Cooling Shroud" on page 79.
NOTICE: Never operate your system with the memory cooling shroud removed. Overheating of the system can
develop quickly resulting in a shutdown of the system and the loss of data.

nter the System Setup program and verify that the setting for the RAC card has changed to reflect
the presence of the card. See
"Using the System Setup Program" on page33
.
See the RAC card documentation for information on configuring and using the RAC card.
Activating the Integrated NIC TOE
To add TCP/IP Offload Engine (TOE) functionality to the system’s integrated NIC, install the TOE
NIC hardware key in the TOE_KEY socket on the system board (
see Figure6-2). For TOE software
installation instructions, refer to the documentation that came with your TOE NIC hardware key.
Microprocessor
You can upgrade the system processor(s) to take advantage of future options in speed and functionality,
or add a second processor. Each processor and its associated internal cache memory are contained in a
land grid array (LGA) package that is installed in a ZIF socket on the system board.
