Setting the DIP Switches

The Express 3000 contains two DIP switches (1 and 2), located on the
Rear Panel. These switches let you physically configure DTE rates and
reset the unit. The factory default position for both switches is
down (ON). Leave the switches in the down (ON) position during the
initial installation. Figure 2-3 shows the location of the switches on the
Rear Panel.
