NOTE: In
Niagara 4.8 and later, there is added support for verifying third party module signatures. Currently third party module signing is optional
in most cases, but this will gradually shift to a requirement over the course of the next few releases. As a result, the Software Installation window is changed to include signature status icons in the Installed Version and Available Version columns indicating the
signature status of the installed and available modules. Attempting to install modules with signature warnings (indicated
by a yellow icon) will cause a signature warning dialog to be displayed, and attempting to install modules with signature
errors (indicated by a red icon) will cause the installation to fail. For more details see, Niagara Third Party Module Signing.
Other differences include the following items.
- The “Configure Runtime Profiles” step reflects the differences in software modules, as refactored for
Niagara 4. However, the basic premise for installing only the types of modules needed for the intended application (preserving storage
space on the controller) remains the same.
- The wizard will not let you commission and install a unit with the factory-default platform user credentials. Instead, a step
requires you to replace this default platform admin user with a different user name, and specify a “strong” password for this
admin account. Optionally, you can create additional platform admin accounts in the controller (up to 20). Each platform admin account must
have a unique user name, and also use a strong password. Note each account has the same (full) platform admin access—users
can change their password, even create additional platform admin accounts.
- The Platform Administration view includes an “SFTP/SSH” option, specifying a common port (22 by default, disabled). Although the SFTP and SSH protocols
are more secure than FTP and Telnet (available in earlier releases), disabling is still recommended, except for troubleshooting
or upon request by technical support.
- If converting the JACE-8000 to run
AX, after first running the
N4-to-
AX conversion distribution file in the
Workbench (which converts the controller to the
AX ‘clean’ state), then switch to the
AX-3.8U1
Workbench to run the Commissioning Wizard. For more details see, “ Converting the controller to
AX.”
-
Niagara 4 cannot successfully configure the system passphrase on the JACE-8000 when it is running the
AX daemon. You must use
AX-3.8U1 instead.
Also, in the
N4 Platform Administration view, the Update Authentication and System Passphrase buttons are disabled when the remote platform is the
AX-3.8U1 daemon. Note, that in release
N4.1, the buttons do not appear disabled, however, setting the system passphrase fails when you attempt to configure it.
