The system shell of a JACE provides simple, menu-driven, text-prompt access to basic Niagara platform settings, including IP network settings, platform credentials, system time, and enabling/disabling FTP and Telnet. Also, you can use it to perform a TCP/IP “ping” from the JACE to another host.
Changes issued in the system shell become immediately effective, except for IP address settings (Update Network Settings). You must reboot the JACE in order for any changed network settings to become effective.
If Telnet is enabled in a JACE, you can also access the JACE’s system shell using a Telnet session. Platform login is still
required (just as with a JACE powered up in serial shell mode).
Be careful when changing items from the system shell, in particular platform account (login credentials) and network settings.
If you change platform login credentials and then lose or forget them, you can restore the “factory default” platform login
credentials—however, you will need to make a serial shell connection, reboot the JACE, and then be careful to press a key
at the appropriate time during JACE boot up.
Figure 34 shows an example main JACE system shell menu.

To select a menu option, type the associated number (1 to 7) or “L” for logout, then press Enter. For example, you may choose Update Network Settings to recover IP access, or to set the IP settings of a new JACE.
Use this menu option to access most of the same IP networking options as available in the Commissioning Wizard step (TCP/IP configuration). When selected, you are prompted for each setting sequentially, starting with hostname (Figure 35).
If a JACE with an installed “WiFi option” (at the time of this document, applies only to a JACE-700 controller), note that
TCP/IP settings for the WiFi card are not configurable from system shell. Instead, a platform connection to the JACE is needed
for the TCP/IP Configuration view, or the equivalent TcpIpPlatformService plugin view in its station’s PlatformServices. For
related details, refer to the NiagaraAX JACE WiFi option - Engineering Notes document.

After you save the network settings, they do not become active until you perform a reboot of the JACE controller. You can
do this when you return to the main system shell menu, by selecting menu option 7 (see Figure 34).
