Qualifying Cabling with the Autotest
29
Tip:
To determine if a fault is caused by a crosstalk or
impedance problem, use the
Find Crosstalk Fault
and
Find Impedance Fault
functions in Diagnostic (
DIAG
)
mode.
•
Fault detected:
A localized impedance fault was
detected. Localized faults are usually caused by bad
connections. Check the cabling at the location given.
See the Appendix for other causes of impedance faults.
•
Fault at connection to tester:
The plug connected to the
tester is bad, or the tester’s connector is damaged.
•
Insertion loss fault:
The cabling’s attenuation is too
high. See the Appendix for causes of insertion loss
problems.
•
1000BASE-T bandwidth fault:
The cable has high
ELFEXT (equal-level far-end crosstalk). This may be
caused by poor-quality cable or connecting hardware.
See the Appendix for other causes of ELFEXT faults.
