Check the Jumper Settings

Check the mainboard jumpers to ensure that the board is con-
figured correctly.
How to Set Jumpers
A jumper consists of two or more pins mounted on the main-
board. 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 (or
shunt) 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.
Open
Short
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.
This illustration shows a 2-pin jumper.
When the 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.
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.
