7 Attach the ribbon cables to the RAC card connectors 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.
a Connect one cable to connector 1 on the RAC card and to RAC_CONN1 on the system board.
b Connect the second cable to connector 2 on the RAC card and to RAC_CONN2 on the system
board.
8 Reinstall the cooling shroud.
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.
9 Close the system. See "Closing the System" on page 53.
10 Reconnect the system to the electrical outlet and turn on the system and attached peripherals.
11 Enter 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 page 35.
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 Figure 6-2.)
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.
Replacing a Processor
CAUTION:
Only trained service technicians are authorized to remove the system cover and access any of the
components inside the system. See your Product Information Guide for complete information about safety
precautions, working inside the computer, and protecting against electrostatic discharge.
1 Prior to upgrading your system, download the latest system BIOS version on support.dell.com.
2 Turn off the system, including any attached peripherals, and disconnect the system from the electrical
outlet.
