Removing a processor
Prerequisites
CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and
simple repairs as authorized in your product documentation, or as directed by the online or telephone service and
support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow
the safety instructions that are shipped with your product.
NOTE: This is a Field Replaceable Unit (FRU). Removal and installation procedures should be performed only by Dell
certified service technicians.
NOTE: If you are upgrading your system, 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.
NOTE: You can update the system BIOS by using the Dell Lifecycle Controller.
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. Keep the Phillips #2 screwdriver ready.
4. Remove the cooling shroud.
5. Remove the heat sink.
WARNING:
The processor is hot to touch for some time after the system has been powered down. Allow the processor
to cool before removing it.
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.
Steps
1. Release the open first socket lever near the unlock icon by pushing the lever down and out from under the tab.
2. Release the close first socket release lever near the lock icon by pushing the lever down and out from under the tab. Lift the lever
90 degrees upward.
3. Lower the open first socket-release lever to lift the processor shield.
4. Hold the tab on the processor shield and lift the processor shield until the open first socket-release lever lifts up.
CAUTION:
The socket pins are fragile and can be permanently damaged. Be careful not to bend the pins in the socket
when removing the processor out of the socket.
5. Lift the processor out of the socket and leave the open first socket-release lever up.
NOTE:
If you are permanently removing the processor, you must install a socket protective cap in the vacant socket
to protect the socket pins and keep the socket free of dust.
NOTE: After removing the processor, place it in an anti-static container for reuse, return, or temporary storage. Do
not touch the bottom of the processor. Touch only the side edges of the processor.
