To install the system board tray assembly:

  1. Position the tray into the cut out on the chassis using the side rails as alignment.
  2. Push the assembly all the way in until flush with the rear chassis. Here is a close up of the side rails.
  3. Connect the following signal cables to the system board: front fan power, power P1, power P4, power switch LED, optical drive signal, hard disk drive signal and speaker.
  4. Install the processor. Ensure that the processor lever is in the open position.
  5. Position the processor over the socket using the alignment triangle as a guide, then insert it into the socket.
  6. Rotate the processor release lever to the closed position. Here is a closer look at the alignment triangle.
  7. Install the heat sink. Position the heat sink assembly over the processor and rotate the two leaf spring retention clamps to the closed position.
  8. Alternately tighten the two screws to prevent damage to the heat sink.
    Note: If the thermal grease becomes contaminated, you must remove it from the processor and heat sink, then you must replace it, using grease from the thermal grease kit.
  9. Install the DIMM. Insert the DIMM straight into the slot and press down on the corners until secured by the latches.
  10. Install the rear fan baffle assembly. Align the tabs on the fan with the slots on the rear frame and lower the assembly into position.
  11. Connect the fan power cable to the system board. Here is a closer look at the assembly tab in the slot on the rear frame.
  12. Position the riser card assembly over the connector using the rear alignment tabs as a guide.
  13. Push down the assembly until fully seated in the connector. Here is a closer look at the assembly properly positioned over the rear alignment tabs.
  14. Return the system to the operational position.
  15. Carefully rotate the drive bay assembly to the closed position, ensuring that the cables are properly routed in the bay to avoid damage.
  16. Close the top cover. Rotate the cover down until secured by the latches.
