Explanation and
Diagram of Jumper/

To modify the operation of the
motherboard, jumpers can be used
to choose settings. Jumpers cre-
ate shorts between two pins and
change the function of the connec-
tor. Pin 1 is identified with a
square.

Mounting the Motherboard in the Chassis
All the motherboards have standard mounting holes to fit different types of
chassis. Chassis may come with a variety of mounting fasteners, made of
metal or plastic. Although a chassis may have both metal and plastic fasten-
ers, 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.

to J32 for an ATX power supply.
See Table 2-1 for pin definitions of
an ATX power supply.

If installing a 370SBM or 370SLM
microATX motherboard, the recom-
mended power supply is a SFX
p o w e r s u p p l y ( t h o u g h a n A T X
power supply also works with a
microATX motherboard). Attach
power supply cables to J32 for a
SFX power supply. See Table 2-2
for pin definitions of a SFX power
supply.
