2-5 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.
2-6 Connecting Cables
Power Supply Connector
After you have securely mounted the
motherboard to the chassis, you are
ready to connect the cables. Attach
a power supply cable to J32 for ATX
power. The S2DG2 has two primary
power supply connectors: J32A and
J32B. You should use both prima-
ries and the secondary connector if
included with your power supply.
See Table 2-2 for pin definitions.

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