How Most Networks Are Started
First networks are usually pretty basic and very easy to install. They are most often started because of a need to share files and programs between a few computers, and the need to share a printer.

The simple network has many advantages:

• One simple connectivity point: the hub
• Easy, inexpensive cabling: twisted-pair cabling
• Quick, simple installation that establishes communication across your new network within minutes: plug and play

• Connect nodes to the first hub until it is full, then begin connecting nodes to a second hub. If the two subnets need to communicate, connect the hubs together or add a bridge or switch.
  
  
• At any time, you can add a node or two. When a printer, CD-ROM, tape backup system, fax/data modem, etc., is connected to the computers on your network, you can share these items without connecting them directly to the hub. One highly prized addition would be a single Internet connection that the entire network can share. Just plug it into the hub.
  
  
• A major cost-saving advantage is that the hub and cabling you chose has not become obsolete.
  
  
• This expansion with workgroups connected to hubs will last you a long time. No network equipment has become obsolete, even though you have expanded several times.

• The next step may be to add a server that combines many of the shared services, by putting the services all in one box.
  
  
• As your network continues to grow, a switch may need to be added to help segment the network and keep your network within Ethernet standards.

1. Begin by establishing where each piece of current equipment will be located and what will be added.
   • Draw a floor plan noting equipment placement.
   • Make a few notes on distance. You will need that later when planning cabling and checking to see if you have stayed within the guidelines of Ethernet networking. Remember, when you expand outside the limits, you will be disappointed in the performance of your network.
   
   
2. Create a list of items you will need.
   • Don't forget network adapter cards. Note the type of equipment that will need a card (including details such as type of operating system and type of computer) so you can get the specific type required. There are more than a dozen types available. Watch for connector types to ensure you get the connectors you need.
   • Have you decided on cabling? When setting up a star network you'll need Category 3 10BASE-T (for 10 Mbps Ethernet) or Category 5 100BASE-TX cable (for either 10 Mbps or 100Mbps Fast Ethernet). The speed of your network will determine the type and quality of your cable.
   • Check how many segments of cable you will need, and lengths of each cable. This will give you an idea of how many hubs, switches, or bridges you may need, if any.
   
   Remember, If you have less than 8 items to connect, one 8-port hub will do nicely?and it uses the simplest of cabling: 10BASE-T (or 100BASE-TX for Fast Ethernet) with modular RJ-45 connectors.
   
   
3. Have you chosen a Network Operating System?
   • If you're using Windows NT*, you already have networking operating software in your computer.
   • Is it on all computers to be networked?
   • Follow the instructions in the provider's manual when setting up your network.
   
   
4. Finally, look at all the equipment, distances and workgroups.
   • Is the network layout the best for my network size?
   • Will people be able to communicate within their workgroups and to the rest of the network as needed?
   • Review Helpful Networking Tips if you are unsure, paying particular attention to cable lengths, overall network distance and number of nodes and hubs on the network.
   
   
5. If you have complied with all the issues of maintaining Ethernet standards, you are ready to proceed.
   • Acquire all necessary equipment and cables.
   • Follow your plan carefully.

• RJ-45's (10BASE-T connectors) should be securely seated.
  
  
• A bad cable should be replaced immediately. Most network failures are cause by poor cable.
  
  
• If you're using BNC (coax) connectors, each connection must be locked securely in place.
  
  
• All open ends of a BNC bus network must have 50 ohm terminators installed.
