432 Practical Modern SCADA Protocols: DNP3, 60870.5 andRelatedSystems Setting up the network is the foundation of all Ethernet practicals in this course. Six computers will be connected to one or more hubs using the 10BaseT cables. Power for the computers and hub/s will be on an as needed basis. The network will be set up as a star/ hub system. This is one of the most used systems in industry. Electrically Parallel Ethernet Star Note: Remember that even though the network has a hub in the system, the NODES or computers are all physically wired in parallel. Parallel Ethernet Bus
Objectives • To show how a basic Ethernet network is setup • To demonstrate the physical layer with an Ethernet network • To implement TCP/IP on an Ethernet network • Define and change the IP address on a computer • To be able to share information from one computer to another • To verify the setting and if needed troubleshoot the network Hardware/software required Appendix D: Practicals 433 No less than one laptop computer per three users One two or three Ethernet hubs One PCMCIA Ethernet card per computer (two for the router) One adapter cable for each Ethernet card (except the Ambicom card, it uses a special cable) At least one 10BaseT cable per computer Windows software (Win95 for all computers except the router) Windows NT installed on the routing computer Implementation/setting up the network Plug in power supplies into the computers (do not turn them on yet) Carefully plug in the adapter cables into the PCMCIA cards Plug in the 10BaseT cables into the PCMCIA adapters and into the HUB/s Hub connections Plug in the hub power supplies (they should now have power) Turn on the computers and let them boot up. Hub Connections When the computer asks you to log on use guest.
