Dell 2900 owner manual Activating the Integrated NIC TOE, Microprocessor, Replacing a Processor

7Attach 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.

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.

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.

9Close the system. See "Closing the System" on page 53.

10Reconnect the system to the electrical outlet and turn on the system and attached peripherals.

11Enter 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
