Figure 9-9 shows the logical network equivalent to the connections shown in Figure 9-7 and Figure 9-8
above. A remote system with PCCU (1) can establish connections to each device (connected to local
switch or daisy-chained) on the same network (3). Each device must have an IP address with the same
subnet assigned to the network. Note that connections lines on the diagram are independent logical
TCP/IP based connections to each device (from a PCCU instance for each). The host connects to the
corporate network (2).
