How to connect the motherboard jumper? Nowadays, many users like to buy computer accessories online and assemble them themselves. Most users have self-taught some installation knowledge through online self-examination, and can assemble the motherboard, graphics card, memory, CPU, and other accessories without any problems. However, some people often get stuck in the motherboard jumper of the computer case.

The jumper between the chassis and motherboard refers to the switch, restart button, USB interface, and headphone microphone interface on the front of the chassis. These interfaces and buttons are all connected to the motherboard through extension cords. Below, we will take you through a comprehensive understanding of these front panel interfaces and jumper connections.

The cables in the chassis mainly include Power SW, Power LED, RESET SW, H.D.D LED, F_USB, and F_AUDIO, which are the cables for the interfaces and indicator lights in the front panel.

Power SW is the most important wiring, officially known as PowerSwitch, meaning power switch, mainly responsible for controlling the switch of the computer host. In fact, its internal function is to short-circuit; RESET SW is also very important, its full name is Reset Switch, which means restart switch and is mainly responsible for controlling the restart of the computer host.

Power LED stands for power indicator light, which is actually the power cord of the power LED light. H.D.D LED is the hard drive indicator light, which is the power cord of the hard drive LED light.

The four sets of cables mentioned above have stumped many novice installers. The names of these four sets of cables may vary slightly for different chassis, but they are generally consistent and can be distinguished with a little attention to detail.

The key is, how to connect these 4 sets of wires to the corresponding positions on the motherboard

The slot in the red box area is where the four sets of wires are connected. The white text immediately below the slot corresponds one-to-one with the pins in the slot, representing the following meanings:

+PLED -: Power indicator light jumper,+represents positive pole, - represents negative pole. This indicator light is usually located near the computer case switch, and the color of the light is mostly green or blue. (The positive and negative poles of this set of wires cannot be reversed, otherwise the indicator light will not light up.)

+HD -: Hard disk indicator light jumper,+represents positive pole, - represents negative pole. This indicator light is also located near the computer case switch, usually red and flashing normally. (The positive and negative poles cannot be reversed, otherwise the indicator light will not light up)

+PW -: Power switch jumper, this set of wires is connected to the power switch of the chassis, and there is no need to distinguish between positive and negative poles.

-RES+: Restart jumper, this set of wires is connected to the chassis restart button, and there is no need to distinguish between positive and negative poles. (Some chassis do not have a restart button, so there is no - RES+jumper)

-CI+: The detection pin on the side panel of the chassis is enabled to prevent theft, so there is no need to worry about it. Simply put, a switch has been added to the chassis cover, which is connected to the - CI+pin. If the chassis cover is opened, the - CI+pin can detect it and sound an alarm.

+SPEAK -: motherboard buzzer jumper. Early motherboards came with built-in buzzers, and when you turned them on, you would hear a "beep" sound, which was emitted from the motherboard buzzer. Nowadays, motherboards no longer come with their own buzzers. If you want to hear the "beep" when turning on, you can connect an external motherboard buzzer to the+SPEAK interface. Note the need to distinguish between positive and negative poles.

+PWR_LED -: This is also a jumper for the chassis power indicator light. Please note that it has 3 pins. Only a very small number of chassis use this set of cables, so we can ignore the existence of this set of cables.

The above are the difficulties of motherboard and chassis jumpers. The most difficult part has been overcome, and the remaining jumpers are much simpler. Let's continue reading.

These jumper connectors have corresponding slots on the motherboard, and are usually labeled with names next to the slots. They are also designed to prevent incorrect insertion (foolproof design). Before inserting, carefully observe the shape of the connector slot to avoid forcefully inserting it.
