Preconditions to Running the Copper Port Test
Before running the test, do the following:
• (Mandatory) Disable Short Reach mode (see the Properties page)
• (Optional) Disable EEE (see the Properties page)
Use a CAT6a data cable when testing cables using (VCT).
The test results have an accuracy within an error range of +/- 10 for advanced Testing and +/-
2 for basic testing.
CAUTION When a port is tested, it is set to the Down state and communications are interrupted. After the
test, the port returns to the Up state. It is not recommended that you run the copper port test on
a port you are using to run the web-based switch configuration utility, because communications
with that device are disrupted.
To test copper cables attached to ports:
STEP 1 Click Status and Statistics > Diagnostics > Copper Test.
STEP 2 Select the unit and port on which to run the test.
STEP 3 Click Copper Test.
STEP 4 When the message appears, click OK to confirm that the link can go down or Cancel to abort
the test.
The following fields are displayed in the Test Results block:
• Last Update—Time of the last test conducted on the port.
• Test Results—Cable test results. Possible values are:
- OK—Cable passed the test.
- No Cable—Cable is not connected to the port.
- Open Cable—Cable is connected on only one side.
- Short Cable—Short circuit has occurred in the cable.
- Unknown Test Result—Error has occurred.
