Working Inside Your Computer

5-5

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 docu-
ments, 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 5-7 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.
