I Concepts & Terms Required - Chapter 1001
The process of critical thinking
is vital to network operations. In the perfect world, everything
would be ready when you asked for it and it would be delivered
exactly as you ordered it. Capital considerations would
not be an issue, since you would have all the money you need,
and everything would be free anyway. You wouldn’t have to
consider interruption of users’ workflow, when considering the
install or upgrade, and everything would fit exactly perfectly,
the first time.
Welcome to planet earth. This
means that everything you have read in the previous paragraph is a big
lie and you must consider all of these events as real factors waiting
for you. As the saying goes, “the best laid plans of mice
and men, surely go asunder.” In this segment, you will
consider first the design, then the installation of the
new network or upgrade of a legacy system.
In this final chapter, we’ll
look at some real-world considerations in the life cycle of a network.
First, we look at some aspects of network design and planning. Then,
we move into implementation – actually installing and configuring
the network. Then, we look at support and maintenance activities that
will help keep your network functioning well.
Finally, we look at troubleshooting
network problems that may occur, and present a general troubleshooting
strategy that is useful as a structured approach to diagnosing and solving
network problems. Here are the specific areas covered in this chapter:
- Applying Patches and upgrades
- Environmental Factors
- Installation considerations
- Maintenance History
- Maintenance Schedule
- Monitoring functionality
- Network Design considerations
- Popular hardware components outside of networking
- Troubleshooting
- Troubleshooting Strategy
- Vendor diagnostics
- Visual inspections and walk through
