Step 19. Remove all heat sinks and microprocessors, and set them aside on a static-protective surface for
reinstallation (see “Removing a microprocessor and heat sink” on page 283).
Notes:
1. Remove the socket covers from the microprocessor frame brackets on the new system board
and place them on the microprocessor sockets of the old system board that you are removing.
2. Use an alcohol wipe to remove any thermal grease from the tabs on the microprocessor
bracket frame on the old system board.
3. Use the microprocessor tool that comes in the system board FRU to remove and replace
microprocessors.
4. Remove the microprocessors from the old system board and place them directly onto the new
system board sockets. Keep the heat sink and microprocessor from each microprocessor
socket of the old system board together so that you can install them on the new system
board on the same socket together. For example, when you remove the heat sink and
microprocessor from microprocessor socket 1 of the old system board, install them both on
the same socket (socket 1) on the new system board.
Step 20. Remove the backplanes and cables, if necessary to access and remove the system board.
Step 21. Loosen the thumbscrews (near the front of the server) that secure the system board to the server
and slide the system board toward the front of the server.
Note:
Remove the drive backplanes, if necessary.

Step 22. Grasp both system-board handles and lift up the left side of the system board slightly and carefully
remove it from the chassis, being careful not to damage any surrounding components.
Note:
Use the system-board handles to lift the system board only. Do not attempt to lift the
server using the system board handles.
Step 23. If you are instructed to return the system board, follow all packaging instructions, and use any
packaging materials for shipping that are supplied to you.
