Lesson 4 Practice

For each of the following pieces of information, give a reason why a network
infra-
structure blueprint would contain that information.
1. Locations of fluorescent light fixtures
For a network that uses copper-based cables, fluorescent light fixtures can
be a significant
source of electromagnetic interference. A network blueprint should contain
the locations of
these fixtures so that the network designer can route cables around them.
2. Cable color
For a network using an external cable installation, matching the cable color
to the wall color can
help make the cables less visible.
3. Ceiling height
Cable length measurements must include vertical as well as horizontal
distances. Specifying
ceiling height enables the network designer to account for vertical cable
runs from the ceiling
down to the wall plate.
4. Size of cable conduits running between floors
The configuration of a large network in a building with several floors can
be partially dependent
on the amount of space available to run cables between floors. If this space
is limited, it might
not be practical to run a large number of cables to centrally located hubs
in a data center. The
designer might have to locate individual hubs on each floor instead.
5. Locations of locked rooms and closets
In most cases, it is best to place servers, hubs, routers, and other
critical or expensive devices
in physically secure locations. A network blueprint should specify these
secure locations.
