Front Panel Components
The following sections list the front panel components on the NX-series controllers. Each component is featured on all
NX-series controllers except where noted.
Power Button
The NX-4200 includes a momentary button on the front panel that you can use to turn on and turn off the unit. When you
apply power to the unit, the power state is always on and the integrated LED is green. If you press the power button for
more than two seconds while the unit is on, the unit turns off and the integrated LED changes to amber. Pressing the
button momentarily while the unit is off turns it on and returns the integrated LED to green.
Note:
The power button does not switch off AC power routed to the internal power supply. If AC power is used on the
unit, AC power will still be present on the power supply AC input connections even when the unit is turned off.
If an internal power fault is detected, the LED integrated into the power button will flash yellow. This is an indication
that the unit requires service.

Program Port
The front panel of all models features one Type-B USB port for connecting the controller to a PC via USB cable.
The Program port uses a standard Type-A-to-Type-B USB cable to connect to a PC. When connected, you can view your
controller among the listed Masters connected via USB in NetLinx Studio. See the Initial Configuration chapter in the
NX-Series Controllers WebConsole and Programming Guide
for more information.
