Some documentation may refer to setting the jumpers to on, off, closed, or open. When a jumper is on or covering at least two pins it is a closed jumper, when a jumper is off, is covering only one pin, or the pins have no jumper it is an open jumper.

How do you tell if a jumper is on or off?
Important Facts About Jumpers
When a jumper is considered “on,” it means that it’s covering at least two pins (this also means it’s a “closed jumper”). A jumper that’s “off” is attached to only one pin. An “open jumper” is when none of the pins are covered with a jumper.
What is jumper on motherboard?
In a computer, a jumper is a pair of prongs that are electrical contact points set into the computer motherboard or an adapter card . When you set a jumper, you place a plug on the prongs that completes a contact. In effect, the jumper acts as a switch by closing (or opening) an electrical circuit.
Where is jumper in motherboard?

Where is jumper in PC?
jumpers are two electrical contacts located on the motherboard or adapter card of a computer. A jumper is a device that connects two points together by placing a plug on each end. As a result, the jumper acts as a switch, closing (or opening) an electrical circuit when it is set.
What are jumper settings?
Jumpers manually configure computer peripherals, such as the motherboard, hard drives, modems, sound cards, and other components. For example, if your motherboard supported intrusion detection, a jumper can be set to enable or disable this feature.
What is a jumper used for?
A jumper is a tiny metal connector that is used to close or open part of an electrical circuit. It may be used as an alternative to a dual in-line package (DIP) switch. A jumper has two or more connecting points, which regulate an electrical circuit board.

What is jumper pin?
Jumper pins (points to be connected by the jumper) are arranged in groups called jumper blocks, each group having at least one pair of contact points. An appropriately sized conductive sleeve called a jumper, or more technically, a shunt jumper, is slipped over the pins to complete the circuit.
Is jumper a switch?
Supplied in units of 1 thru 16 poles they provide an alternative to jumpers without the need for ‘parking pins’ on the PCB or exposed bare pins and are available with ON/OFF (JSA4), CHANGEOVER (JSC4), and CENTRE-OFF (JSK9) switch actions.
