Planning for Network Operations
Create a Network Log
A network log is a record of the names of devices, cable locations, wall-jack
numbers, and other information about the network. A simple network log
may contain the name, description, node number, and BNC Hub/6 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. Consider
creating a network log to use as a reference when you are installing and
managing the network. An up-to-date network log ensures that records of
network equipment are always readily available. Having a complete written
record of your network will make troubleshooting easier.
Consider Future Expansion
As your network needs grow, your network should also grow. Hasty addi-
tions to your network make network maintenance difficult and time-con-
suming. Plan to install more cabling and T-connectors than you think you
will need. With adequate preparation, adding another device to the network
can often be as simple as plugging in another network connection.
Determine Application Needs
Think about how people on the network plan to use it. Will they be occa-
sionally printing, exchanging electronic mail, or transferring files? Will some
users regularly access a multi-user database, transfer large graphics or CAD
files, or launch applications from a server? Depending upon your users’
application needs, you might want to break your network into smaller clus-
ters (segments) using bridges and routers.
Cabling Requirements
There are several fundamental rules you must follow:
❏ The network must be arranged in a linear “bus” configu-
ration.
❏ Use only RG-58A/U coaxial cable. (RG-58U cable is simi-
lar, but it does NOT meet IEEE specifications.)
❏ Each end of the linear cable must have a 50 Ω terminator
installed.
