System board jumpers and switches
This topic provides information about the jumpers and switches on the system board.
A jumper is a short length of conductor used to set up or adjust printed circuit boards, such as the system
board of a computer. A jumper usually is encased in a non-conductive block of plastic for convenient use
and to avoid any possible damage to a live circuit. Jumper pins arranged in groups on the system board are
called jumper blocks. When two or more jumper pins are capped with a jumper, an electrical connection is
made between them and the equipment is thus instructed to activate certain settings accordingly.
The following illustration shows a jumper in the default setting position (pin 1 and pin 2). This is the correct
position for normal operation.
