Troubleshooting should include an explanation of how to solve the problem, and the following:
- Shorts
- Opens
- Incorrect termination (mismatched standards)
- Straight-through
- Crossover
- Cross-talk
- Electromagnetic Interference (EMI)/Radio Frequency Interference (RFI)
- Distance limitations
- Attenuation/Decibel (Db) loss
- Bad connector
- Bad wiring
- Split pairs
- Tx/Rx reverse
- Cable placement
- Bad Small Form-factor Pluggable (SFP)/Gigabit Interface Converter (GBIC)
Process/Skill Questions:
- What methods can be used to mitigate EMI/RFI?
- What is cross-talk? What are some methods to eliminate it?
