It is also possible to connect the Edge devices to the secondary port of the JACE. In this arrangement, the network of JACEs becomes a private network, isolated from the network to which the primary port of the JACE is connected. When connected to the secondary port, the JACEs are not directly reachable from the main network, and NiagaraNetwork provisioning running on the JACE station must be used to setup and manage the controllers.
Note that prior to connecting JACEs to the secondary port of the JACE, you must either preconfigure the devices with static IP addresses, or enable the DHCP server on the JACE.
