System Board Jumpers
Figure 4 shows the layout of jumpers on the system board. Table 1 lists the system board jumpers and their
settings.
Figure 4. System Board Jumpers
Jumpers are small blocks on a circuit board with two or more pins emerging from them. Plastic plugs
containing a wire fit down over the pins. The wire connects the pins and creates a circuit.
To change a jumper setting, pull the plug off its pin(s) and carefully fit it down onto the pin(s) indicated.
NOTICE: Make sure your system is turned off and unplugged before you change a jumper setting.
Otherwise, damage to your system or unpredictable results may occur.
