Cable diagnostics are performed using Digital Signal Processing (DSP)
test methods.
This cable test is only accurate for cables 7 - 140 meters long.
The test takes approximately 5 seconds. The switch displays the results
of the test immediately upon completion, including common cable
failures, as well as the status and approximate length of each cable
pair.
Potential conditions which may be listed by the diagnostics include:
OK: Correctly terminated pair
Open: Open pair, no link partner
Short: Shorted pair
Not Supported: This message is displayed for any Fast Ethernet
ports that are linked up, or for any Gigabit Ethernet ports linked up
at a speed lower than 1000 Mbps.
Impedance mismatch: Terminating impedance is not in the
reference range.
Ports are linked down while running cable diagnostics.
