socket identified by a corresponding triangle.
12. Install the processor in the socket.
a. If the release lever on the processor socket is not positioned all the way up, move it to that position.
b. With the pin-1 corners of the processor and socket aligned, set the processor lightly in the socket, making sure all pins are matched with the
correct holes in the socket.
Because the system uses a ZIF processor socket, do not use force, which could bend the pins if the processor is misaligned.
When the processor is positioned correctly, it drops down into the socket with minimal pressure.
c. When the processor is fully seated in the socket, rotate the socket release lever back down until it snaps into place, securing the processor.
13. Install the heat sink.
a. Using a clean lint-free cloth, remove the existing thermal grease from the heat sink.
b. Apply thermal grease evenly to the top of the processor.
c. Place the heat sink onto the processor. See Figure 6 -18 .
d. Close one of the two heat sink retention levers until it locks. See Figure 6 -18 .
e. Repeat for the other heat sink retention lever.
14. Reinstall the center fan bracket. See " Replacing the Center Fan Bracket ."
15. If you have added a second processor, install the two processor cooling fans for the new processor. See " Installing and Removing a Processor Fan ."
16. Close the system. See " Closing the System " in "Troubleshooting Your System."
As the system boots, it detects the presence of the new processor and automatically changes the system configuration information in the System Setup
program.
17. Press to enter the System Setup program, and check that the processor information matches the new system configuration.
See your User's Guide for instructions about using the System Setup program.
18. Run the system diagnostics to verify that the new processor operates correctly.
See " Running the System Diagnostics " for information about running the diagnostics and troubleshooting processor problems.
Installing a RAC Card
1. Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
2. Open the system. See " Opening the System " in "Troubleshooting Your System."
3. Remove the memory cooling shroud by lifting the release latch and sliding the shroud forward. See Figure 6 -16 .
4. Remove the two memory module fans at the back of the system. See " Removing a Memory Module Fan ."
5. Remove the back fan bracket. See " Removing and Replacing the Back Fan Bracket ."
6. Remove the filler plug from the system back panel. See Figure 6 -20 .

NOTICE: Positioning the processor incorrectly can permanently damage the processor and the system when you turn it on. When placing the processor
in the socket, be sure that all of the pins on the processor enter the corresponding holes. Be careful not to bend the pins.
NOTE: Use the heat sink that you removed in step 7 .
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.
