To install the system board tray assembly:
- Position the tray into the cut out on the chassis using the side rails as alignment.
- Push the assembly all the way in until flush with the rear chassis. Here is a close up of the side rails.
- 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.
- Install the processor. Ensure that the processor lever is in the open position.
- Position the processor over the socket using the alignment triangle as a guide, then insert it into the socket.
- Rotate the processor release lever to the closed position. Here is a closer look at the alignment triangle.
- Install the heat sink. Position the heat sink assembly over the processor and rotate the two leaf spring retention clamps to the closed position.
- 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.
- Install the DIMM. Insert the DIMM straight into the slot and press down on the corners until secured by the latches.
- 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.
- 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.
- Position the riser card assembly over the connector using the rear alignment tabs as a guide.
- 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.
- Return the system to the operational position.
- Carefully rotate the drive bay assembly to the closed position, ensuring that the cables are properly routed in the bay to avoid damage.
