1 Planning a Network Installation • Before You Start on page 1-2 • Assign a Network Manager on page 1-3 • Create a Network Map on page 1-4 • Planning for Network Operations on page 1-5
Planning a Network Installation Before You Start An efficient network that will serve your long-term needs requires thorough planning.This chapter discusses some of the topics that are important in the early stages of network development.The topics are arranged in chronological order.You should read this entire chapter to get an overview of the details involved in planning your network.
Assign a Network Manager Assign a Network Manager A network manager initially coordinates the design and installation of the network. Once the network is up and running, the network manager is responsible for adding new users to the network and troubleshooting problems. For small installations, the network manager’s duties may only require a few hours a week. For larger installations, the network manager’s position may be a full-time job.
Planning a Network Installation Create a Network Map A network map is a visual record of your network configuration. Create a network map by copying a floor plan diagram and adding graphics representing devices and cabling. Modify the map as you change your plans, and use the completed map as a guide during installation. It is a good idea to create the map on a computer so you can easily modify it.
Planning for Network Operations Planning for Network Operations Create a Network Log A network log is a record of the names of devices, locations of wire pairs, wall-jack numbers, and other information about the network. A simple network log may contain the name, description, node number, and 10T Hub port number for each device on the network. A more detailed log may contain the serial number of each device, the network number, and more.
Planning a Network Installation ❏ ❏ ❏ You must use solid copper (not stranded) twisted-pair wiring.You can identify twisted-pair wire by alternating color bands: white/blue, blue/white, white/orange, orange/white, and so on. Use approved building wiring standards or consult a professional The maximum twisted-pair link-length from hub to transceiver, including the RJ-45 cable, is 100 meters (328 feet).
