1.The Ethernet connection to the corporate network in this figure is a nondedicated network. IP addresses for the various components of the S8700-series fiber-PNC configuration must be administered to prevent conflicts with other equipment that shares the network. In the default S8700 fiber-PNC configuration, all other Ethernet connections operate on their own closed LANs.
