NOTE: To ensure proper system cooling, you must install a processor blank in any empty processor socket.
1. Follow the safety guidelines listed in the Safety instructions section.
2. Follow the procedure listed in the Before working inside your system section.
3. If you are upgrading your system (from a single processor system to a dual processor system or a processor with a higher processor
bin), download the latest system BIOS version from Dell.com/support and follow the instructions included in the compressed
download file to install the update on your system.
4. If connected, disconnect the cables from expansion card(s).
5. If installed, remove the PCIe expansion card riser.
6. Remove the cooling shroud.
7. Remove the heat sink.
8. Keep the Phillips #2 screwdriver ready.
Steps
1. Using a clean, lint-free cloth remove any thermal grease from the surface of the processor shield.
CAUTION: The processor is held in its socket under strong pressure. Be aware that the release lever can spring up
suddenly if not firmly grasped.
2. Position your thumb firmly over the socket-release lever 1 and lever 2 of the processor and release both the levers simultaneously from
the locked position by pushing down and out from under the tab.

3. Hold the tab on the processor shield and rotate the shield upward and out of the way.
4. Lift the processor out of the socket and leave the release lever up so that the socket is ready for the new processor.
CAUTION: If you are permanently removing a processor, you must install a socket protective cap and a processor
blank in the vacant socket to ensure proper system cooling. The processor blank covers the vacant sockets for the
DIMMs and the processor.
