Mounting the Motherboard in the Chassis

All the motherboards have standard mounting holes to fit different types of chas-
sis. Chassis may come with a variety of mounting fasteners made of metal or
plastic. Although a chassis may have both metal and plastic fasteners, metal
fasteners are the most highly recommended because they ground the system
board to the chassis. Therefore, use as many metal fasteners as possible for
better grounding.

Connecting Cables

Power Supply Connector

After you have securely mounted
the motherboard to the chassis,
you are ready to connect the
cables. See page 1-27 for
power supply requirements.
Attach the ATX power supply
cables to J32. See Table 2-2 for
the pin definitions of an ATX
power supply.

Secondary Power Connector

The Secondary Power Connector
is recommended when a heavy
load of peripherals has been
connected to the motherboard.
Note: Be sure to use a 1 X 6 pin connector
and check the power supply layout before
The Secondary Power
attaching it.
Connector is located on J36.
See Table 2-3 for pin definitions.

Infrared Connector

The infrared connector is located on
pins 1-5 of JF2. See Table 2-4 for pin
definitions.
