Connecting to the JACE debug system shell

The following procedure provides steps to use the system shell. Examples provided use the PuTTY terminal emulation program.

Prerequisites:

Physical access to the JACE controller
Universal USB-to-MicroUSB connector cable

NOTE: Starting in Niagara 4.2, the JACE-8000 can be converted (downgraded) to run AX-3.8U1–with some feature limitations. For example, for any JACE-8000 running AX the USB functionality is not supported. In this configuration the USB port on the device is not monitored for insertion/removal of devices.

Perform the following steps:

Connect the USB cable between the controller’s Debug port and the USB port you are using on your PC.
On your PC, start your terminal emulation software. For example to start PuTTY from the Windows Start menu, this is typically Programs > PuTTY > PuTTY.
In the tree in the PuTTY Configuration dialog, expand Connection and click Serial.
Set the “Serial line to connect to” for your PC’s (USB) COM port to use. For example, COM3.

NOTE: You can examine Ports in Windows Device Manager to determine which serial port is in use on the PC.
Set the “Configure the serial line” fields as follows:
- Speed (baud): 115200
- Data bits: 8
- Stop bits: 1
- Parity: None
- Flow control: None
In the tree in the PuTTY Configuration dialog, click Session and then click/select the “Connection type” as Serial

NOTE: (Optional) You can save this configuration to reuse (load) in future PuTTY to JACE serial sessions. To do this, type in a connection name in the “Saved Sessions” field (for example, “JACE-8000-S”), and click Save.When you start PuTTY again to serially connect to the JACE, select this name and click Load.
At the bottom of the PuTTY Configuration dialog, click Enter.
At the login prompt, enter a platform user name, and at the password prompt, the platform password.
1. If prompted for system passphrase, enter the platform’s system passphrase.
If login is successful, the System Shell menu appears:
When finished making platform changes from the system shell, do the following:
- If no changes, or reboot is not necessary, simply type L to Logout.
- If changes require rebooting, select the Reboot option.
  Type “y” at the “Are you sure you want to reboot [y/n]” prompt, and press Enter.
  
  Shutdown-related text appears in the terminal (PuTTY) window.
Click the Close control (upper right corner) in the terminal session (PuTTY) window.  Click OK in the “PuTTY Exit Confirmation” popup dialog.
Unplug the USB connector from the JACE’s Debug port.
