1	SHUT DOWN: Push button switch for a controlled shutdown. The SHUT DOWN push button initiates a controlled shutdown of the controller, ensuring that all station data are preserved. This provides an alternative to the platform stop station command while the controller is connected online. Refer to “Initiating a controller shutdown” for details.
2	SHUT DOWN LED (Green) Shut down "job in progress" indicator.
3	DEBUG: The DEBUG port is a USB-C port for serial debug communications to the controller only.

You can use a serial terminal program (for example: PuTTY) with the DEBUG port to access the controller’s system shell menu. This provides access to a few basic platform settings. Default DEBUG port settings are: 115200, 8, N, 1 (baud rate, data bits, parity, stop bits). For more details, refer to the JACE-9000 Install and Startup Guide.
