◆
Cable diagnostics are performed using Digital Signal Processing (DSP)
test methods. DSP analyses the cable by sending a pulsed signal into
the cable, and then examining the reflection of that pulse.
◆
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.
