The "jumpers" of the internal boards of the computer are small metal rods (jumper posts) embedded on the motherboard, sound card, hard disk and other equipment, and small clips (jumper clips) on these metal rods. The function of the jumper is to adjust the on-off relationship of different electrical signals on the device, and to adjust the working state of the device, such as determining the motherboard voltage, the master-slave relationship of the driver, and so on. When the jumper clip is covered with two jumper posts at the same time, it means that the two jumper posts are connected. If only one or not covered, it means that it is disconnected. It is very important to adjust the jumper. If the jumper is wrong, it will crash, or even burn the entire device. Therefore, when adjusting the jumper, be sure to read the manual carefully, check the name of the jumper, the number of the jumper column and the on-off relationship.
Il-jumpers fuq il-motherboard ġeneralment jinkludu jumpers ta 'l-issettjar ta' CPU, jumpers ċari CMOS, jumpers ta 'projbizzjoni tal-kitba tal-BIOS, eċċ. Fosthom, il-jumper ta' l-issettjar tas-CPU huwa l-aktar ikkumplikat. Jekk il-motherboard huwa relattivament antik, il-vultaġġ tal-qalba, l-FSB, u l-jumpers tal-multiplikatur tal-frekwenza għandhom jiġu ssettjati fuq il-motherboard. Issettja l-jumpers korrispondenti ta 'hawn fuq skont il-manwal tal-motherboard u l-frekwenza tas-CPU. F'ċirkostanzi normali, il-vultaġġ korrispondenti tas-CPU fuq il-motherboard huwa sett ta 'jumpers, kull jumper jikkorrispondi għal valur ta' vultaġġ, sib il-valur tal-vultaġġ xieraq, daħħal keycap biex iqassarha, u agħżel dan il-valur tal-vultaġġ. Bl-istess mod, sib il-jumper tal-FSB u l-jumper tal-multiplikatur, u ssettja l-FSB u l-multiplikatur xierqa rispettivament. Innota li jumper wieħed biss f'kull grupp ta 'jumpers jistgħu jintgħażlu għal shorting.
The jumper here refers to the copper connecting wire, which is made of standard jumper cable and connecting hardware. The jumper cable has copper cores ranging from two to eight cores, and the connecting hardware is two 6-bit or 8-bit modular plugs. , or they have one or more bare wire ends. Some jumpers have a modular plug on one end and an 8-position modular slot on the other, or are fitted with 100P patch cords, MICs, or modular slots. Jumpers are used to connect various links on the patch panel, and can be used as patch panels or equipment connection cables. Both ends of the modular jumper are RJ45 connectors, adopt TIA/EIA-568A pin structure, and have a flexible plug-in design to prevent loosening and jamming. Patch cords are available in lengths from 1 foot (0.305 m) to 500 feet (15.25 m), with 3, 5, 7 and 10 foot lengths being the most common. Modular patch cords are used in the work area and also as patch cords in the wiring closet. In small office network or home network DIY installations, dual-connection jumpers are often mentioned. This kind of jumper is not a standard jumper used in integrated wiring, but a special hardware device connection cable. It is used when two PCs are directly connected by a twisted pair, or when two HUBs are connected through the RJ45 port. , you need a crossover (commonly known as cross-connect line, jumper). It follows a special connection order.
