Isolating Problems
The key to problem solving in this system is to try to isolate the problem to a specific
subsystem. By comparing what the system is doing to what it should be doing, the task of
isolating the problem is greatly simplified.
When problem solving, consider the following subsystems:
•
Power and cooling systems—The power supply, power cable, and fan
•
Ports and cables—The ports on the rear panel of the router and the cables that connect
to them
