Use the decision tree in Figure 1 to determine which of the four network architectures described in Network architecture is best suited for a particular deployment. It is assumed that the facilities manager or field personnel have access to the Metasys devices from a Metasys server connected to the IT network (if an IT network exists).
*In the case of new construction, a provisional network will need to be deployed before the availability of the IT network. In this case, an Isolated Metasys IP Network will initially be deployed which can later be migrated to a Connected Metasys IP Network and connected to the IT network by way of a single routed port. To minimize configuration changes required for the migration to a Connected network, it is recommended that the initial isolated network be deployed using the VLANs and IP addresses which will ultimately be used when the network is connected to the IT network.
