4. Ensure that all internal cables are routed correctly and connected, and no tools or extra parts are left inside the system. 5. Open the drive bays, remove all drives, and then close the drive bays. 6. Remove the power supply units. 7. Remove the system from the rack and place it on an ESD work bench. For more information, see the Rail Installation Guide available at www.dell.com/poweredgemanuals. 8. Remove the system cover. 9. Remove the air shroud. 10. If installed, remove the rear drive cage. 11. If installed, remove the risers. 12. If installed, remove the processor dust cover. Steps 1. Align the pin 1 indicator of the heat sink to the system board and then place the processor and heat sink module (PHM) on the processor socket. CAUTION: To avoid damaging the fins on the heat sink, do not press down on the heat sink fins. NOTE: Ensure that the PHM is held parallel to the system board to prevent damaging the components. 2. Push the blue retention clips inward to allow the heat sink to be lowered into place. 3. Using the Torx #T30 screwdriver, tighten the screws on the heat sink in the order below: a. Partially tighten the first screw (approximately 3 turns). b. Tighten the second screw completely. c. Return to the first screw and tighten it completely. If the PHM slips off the blue retention clips when the screws are partially tightened, follow these steps to secure the PHM: a. Loosen both the heat sink screws completely. b. Lower the PHM on to the blue retention clips, following the procedure described in step 2. c. Secure the PHM to the system board, following the replacement instructions listed in step 3. Figure 81.
