Cable Diagnostics Test
Tools > Diagnostics
The switch provides a basic cable diagnostic tool in the GUI for verifying the pairs in
copper cabling and estimated distance for troubleshooting purposes.
Note:
1. If the cable length displays N/A, it means that the cable length is Not
Available. The may be due to the port being unable to determine the estimated
cable length. If length is displayed as “N/A” it means the cable length is “Not
Available”. This is due to the port being unable to obtain cable length/either
because its link speed is 10M or 100M, or the cables used are broken and/or of
bad in quality.
2. The deviation of “Cable Fault Distance” is +/- 2 meters. No cable may be
displayed in the table when the cable is less than 2 meters in length.
3. The test also measures the cable fault and identifies the fault in length
according to the distance from the switch.
1. Log into your switch management page (see “Access your switch management page”
on page 5).
2. Click on Tools and click on Cable Diagnostic.
3. Click on the Port drop-down list to select which port to run the cable diagnostic and
click Test Now to run the test.
The results will be displayed in the Cable Diagnostic Table below.
 Test Results: Displays the diagnostic results for each pair in the cable. One of
the following cable status parameters is displayed:
o OK: There is no problem detected with the cable.
o Open in Cable: There is an open wire within the cable.
o Short in Cable: Two wires are shorted together within the cable.
o Cross talk in Cable: There is crosstalk detected between one pair
o of wires and another pair within the cable.
 Cable Fault Distance: This parameter specifies the distance from the switch
port to the cable fault.
 Cable Length: This parameter specifies the length of the cable connected to the
switch port.
