Copper Ports Tests
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 results 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

• (Mandatory) Disable Short Reach mode (see the Port Management > Green Ethernet > Properties
page)
• (Optional) Disable EEE (see the Port Management > Green Ethernet > Properties page)
Use a CAT5 data cable when testing cables using (VCT).
