Jumpers and switches provide a convenient and reversible way of reconfiguring the
circuitry on a printed circuit board. When installing replacement parts or reconfiguring
the system, you may need to change jumper settings on the system board. You may
also need to change jumper and/or switch settings on expansion cards or drives.

Jumpers

Jumpers are small blocks on a circuit board with two or more pins emerging from
them. Plastic plugs containing a wire fit down over the pins. The wire connects the
pins and creates a circuit. To change a jumper setting, pull the plug off its pin(s) and
carefully fit it down onto the pin(s) indicated.

Figure A-1. Jumper

NOTICE: Make sure the system is powered off before you change a jumper
setting. Otherwise, damage to the system or unpredictable results may
occur.

A jumper is referred to as open or unjumpered when the plug is pushed down over
only one pin or if there is no plug at all. When the plug is pushed down over two pins,
the jumper is referred to as jumpered. The jumper setting is often shown in text as
two numbers, such as 1-2. The number 1 is printed on the circuit board so that you
can identify each pin number based on the location of pin 1.
