◆ 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 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.
PARAMETERS
These parameters are displayed in the web interface:
◆ Port – Switch port identifier. (Range: 1-48)
◆ Type – Displays media type. (GE – Gigabit Ethernet)
◆ Link Status – Shows if the port link is up or down.
◆ Test Result – The results include common cable failures, as well as the
status and approximate distance to a fault, or the approximate cable
length if no fault is found.
To ensure more accurate measurement of the length to a fault, first
disable power-saving mode on the link partner before running cable
diagnostics.
For link-down ports, the reported distance to a fault is accurate to
within +/- 2 meters. For link-up ports, the accuracy is +/- 10 meters.
◆ Last Updated – Shows the last time this port was tested.
