About the JACE-9000 system shell menu

The system shell of the controller provides simple, menu-driven, text-prompt access to basic Niagara platform settings, including IP network settings, platform credentials, system time, and well as creating or restoring system backups. Also, you can use it to perform a TCP/IP ping from the controller to another host and, in Wi-Fi models, there is access to Wi-Fi configuration menus.

Changes issued in the system shell become immediately effective, except for IP address settings (Update Network Settings). You must reboot the controller for any changed network settings to become effective.

If SSH is enabled in the controller, you can also access the controller’s system shell using a remote terminal session using SSH. Platform login is still required (just as with the controller powered up in serial shell mode).

CAUTION: Be careful when changing items from the system shell, in particular platform account (login credentials, system passphrase) and network settings. If you change platform login credentials and then lose or forget them, you may need to restore the factory default settings and possibly lose any non-backed up data.

Following, is an example of the system shell menu when connected to a JACE-9000.

For example,

  • type 2 (Update Network Settings) to recover IP access, or to set the IP settings of a new controller.

  • type 6 (Change System Passphrase) to change the system passphrase of the unit. You might do this if swapping in a microSD card from a previously configured unit, in order to change the passphrase of the unit to match the passphrase that is already stored on the card.
