Diagnostics
Copper Test
The Copper Test page displays the results of integrated cable tests performed on copper cables
by the Virtual Cable Tester (VCT).
VCT performs two types of tests:
•
Time Domain Reflectometry (TDR) technology tests the quality and characteristics of a
copper cable attached to a port. Cables of up to 140 meters long can be tested. These
r
esults are displayed in the Test Results block of the Copper Test page.
•
DSP-based tests are performed on active GE links to measure cable length. These results
are displayed in the Advanced Information block of the Copper Test page.
Preconditions to Running the Copper Port Test
Before running the test:
•
(Mandatory) Disable Short Reach mode (go to Port Management > Green Ethernet >
Properties)
•
(Optional) Disable EEE (go to Configuration > Port Management > Green Ethernet >
Properties page)
Use a CAT5 data cable when testing cables using (VCT).
Accuracy of the test results can have 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.
