How To Set Jumpers - PCchips M757MR Manual

The mainboard has a set of I/O ports on the rear edge. Ensure that your
case has an I/O template that supports the I/O ports and expansion slots.

How to Set Jumpers

A jumper consists of two or more pins mounted on the mainboard. Some
jumpers might be arranged in a series with each pair of pins numbered
differently. Jumpers are used to change the electronic circuits on the
mainboard. When a jumper cap is placed on two jumper pins, the pins
are SHORT. If the jumper cap is removed (or placed on just a single pin)
the pins are OPEN.
This illustration shows a 2-pin jumper. When the
OPEN jumper cap is placed on both pins, the jumper is
SHORT. If you remove the jumper cap, or place the
jumper cap on just one pin, the jumper is OPEN.
SHORT
This illustration shows a 3-pin jumper. The jumper cap is
placed on pins 2 and 3, so this jumper setting is SHORT
PINS 2-3.
This illustration shows the same 3-pin jumper. The jumper
cap is placed on pins 1 and 2, so this jumper setting is
SHORT PINS 1-2.
In this manual, all the jumper illustrations clearly show the pin numbers.
When you are setting the jumpers, make sure that the jumper caps are
placed on the correct pins to select the function or feature that you want
to enable or disable.
