To change a jumper setting, pull the plug off its pin(s) and carefully fit it down onto the pin(s) indicated. A jumper is referred to as open or unjumpered when the plug is pushed down over only one pin or if there is no plug at all. When the plug is pushed down over two pins, the jumper is referred to as jumpered. In some documents, the jumper setting may be shown in text as two numbers, such as 1-2. The number 1 is printed on the circuit board so that you can identify each pin number based on the location of pin 1. Figure 5-6 shows the location and default settings of the jumper blocks on your system board. See Table 5-1 for the designations, default settings, and functions of your system's jumpers. Switches control various circuits or functions in your computer system. The switches you are most likely to encounter are dual in-line package (DIP) switches, which are normally packaged in groups of two or more switches in a plastic case. Two common types of DIP switches are slide switches and rocker switches (see the following illustration). slide switches rocker switches Each of these switches has two positions, or settings (usually on and off). To change the setting of a slide switch, use a small, pointed object such as a small screwdriver or a straightened paper clip to slide the switch to the proper position. To change the setting of a rocker switch, use the screwdriver or paper clip to press down on the appropriate side of the switch. In either case, do not use a pen, pencil, or other object that might leave a residue on the switch. Working Inside Your Computer 5-7

Each of these switches has two positions, or

ting of a rocker switch, use the screwdriver or paper clip to press down on the
appropriate side of the switch. In either case, do not use a pen, pencil, or other object
that might leave a residue on the switch.
