In electronics and particularly computing, a jumper is a short length of conductor used to close, open or bypass part of an electronic circuit. They are typically used to set up or configure printed circuit boards, such as the motherboards of computers.
What jumpers are used for on hard drives?
The jumper pins are similar to the pins on the I/O plate on a motherboard. You enable particular settings by placing a jumper shunt onto specific pins—creating an electrical circuit between them. The settings these jumpers enable are hard-coded onto a drive’s programmed printed circuit board.

Is it OK to bypass a fuse with a jumper wire?
If the jumper wire is of too small a gauge, it may overheat and possibly melt. Never use jumpers to bypass high resistance loads in a circuit. Bypassing resistances, in effect, creates a short circuit. This may, in turn, cause damage and fire.
Where can you use jumper wires?
Attach one red jumper cable clamp to the positive terminal on the dead battery. Attach the other end of the same cable, the second red jumper cable clamp, to the positive terminal on the working (live) car battery. Attach one black jumper cable clamp to the negative terminal of the working (live) car’s battery.
Can you clear CMOS without jumper?
If there is no CLR_CMOS jumpers or [CMOS_SW] button on the motherboard, please follow the steps to clear CMOS: Take out the battery gently and put it aside for about 10 minutes or longer. (Or you can use a metal object to connect the two pins in the battery holder to make them short-circuited.)
