Replacing the system board 96 Hardware Maintenance Manual This procedure describes how to remove and replace a system board. The procedure varies depending upon the machine type. Important The heat sink and microprocessor might be very hot. Make sure these components are cool enough to safely handle before continuing this procedure. Note: When replacing the system board you must also order a new retention module for the new system board. Make sure you have a retention module for the new system board before continuing with this procedure. 1. Remove the cover. See “Removing the cover” on page 89. 2. Lift the fan duct off the heat sink fan. 3. Remove any adapter cards installed in the PCI connectors. 4. You might have to remove the drive bay assembly to access the system board. See “Accessing system board components and drives” on page 90. 5. Take note of the location of all cable connections on the system board and disconnect all cables. See the system board illustration for your machine type at “System board connectors” on page 88. 6. Remove the hard disk drive. See “Replacing the hard disk drive” on page 103. 7. Remove the screws that secure the system board to the chassis. 8. Lift the system board out of the chassis. 9. Remove the memory modules from the failing system board and install them in the same location on the new system board. 10. Disconnect the heat sink and fan assembly cable from the system board. See the system board illustration for your machine type at “System board connectors” on page 88. 11. Remove the four screws ▌1▐ securing the heat sink and fan assembly to the system board.
12. Lift the heat sink and fan assembly off the failing system board. Place the heat sink on its side so that the thermal grease does not come in contact with anything. Note: You might have to gently twist the heat sink to free it from the microprocessor. 13. Remove the microprocessor from the failing system board. See “Replacing the microprocessor” on page 99. 14. Remove the microprocessor socket cover from the new system board. 15. The failing system board must be returned with a microprocessor socket cover to protect the pins during shipping and handling. Install the microprocessor socket cover removed from the new system board on the failing system board. To install the microprocessor socket cover: a. Make sure the microprocessor has been removed from the microprocessor socket, and then close the microprocessor retainer and lock it into position with the small handle. b. Insert the tabs ▌1▐ of the socket cover into the hinged side of the socket, and then press the other side of the socket cover downward until the tabs ▌2▐ snap into position. 16. Install the new system board into the chassis and align the screw holes with those in the chassis. Insert and tighten the screws that secure the system board. 17. On the new system board, release the lever securing the microprocessor retainer and then pivot the retainer until it is fully open. Note: There will be a black plastic cover on the microprocessor retainer to protect the socket on the new system board. Remove the black plastic Chapter 8. Replacing FRUs- Rocky computers 97
