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 net-
work log may contain the name, description, node number, and 10T Hub
port number for each device on the network. A more detailed log may con-
tain the serial number of each device, the network number, and more. Con-
sider 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 writ-
ten 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 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 mail, or transferring files? Will some users regu-
larly 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 clusters (seg-
ments) using bridges and routers.
Determine If You Can Use Existing Wiring
The physical limitations and regulations on the use of your building’s wiring
can greatly affect your choice of network layouts. Have the building manager
or a telephone installer determine whether you can use existing wiring in
your office. In general, you can use existing wiring if you have two unused
wire pairs (four wires total) going to each network node.
There are four fundamental rules you must follow:
❏
The wire must be 24-gauge, unshielded, twisted-pair,
solid-conductor.
