5.4. Motherboard Assembly

The motherboard is the first component to be assembled to the system compartment. Follow the steps below to assemble the motherboard to the system chassis. Make sure the CPU with cooling fan and SDRAM are already properly installed to the motherboard before the motherboard is attached to the system chassis. (Refer to Sec. 5-2 and 5-3 for CPU and SDRAM installation).

1.The lower side of the chassis has a rectangle opening at the bottom of the chassis. Make the lower side of the chassis to be near you.

2.From your point of view, the motherboard module is to be installed to the lower side of the system compartment.

3.Tape the motherboard insulator (5) (Fig. 5-1 & 5-2 (5)) to

the motherboard (6) first. The insulator is to separate the electronic components on the reverse side of the motherboard from the metal compartment to prevent short circuitry caused during system operation.

4.Fix the motherboard (6) to the chassis with 7 round-head anti-fallen 3*6 screws.

5.The IR/LED cable (Fig. 5-7 (7) & Fig. 5-8 (5)) has to go through the rectangle opening located at the bottom side of the chassis, then connected to motherboard’s J7, the HDD LED & ACPI LED & SMI connector.
