Virtual Cable Tester (VCT)
The VCT feature significantly reduces networking and support costs by virtually diagnosing and reporting cable faults using the Time Domain Reflectometry (TDR) technology. With VCT, you can identify open and shorted cables with up to 10 meters of accuracy.
Using the VCT feature
To do a cable test using VCT:
1.Press the VCT button once.
The switch goes into VCT mode and the system LED turns amber. All port LEDs are off, except the PORT SELECT (STATUS) LED.
2.Press the SEL button to select the port you wish to test. The PORT SELECT (STATUS) LED of the selected port lights up.
NOTE. If no other action is taken after the VCT or SEL button is pressed, the switch automatically goes back to normal operation after
15seconds.
3.Press the VCT button again to execute VCT on the selected port. The PORT SELECT (STATUS) LED of the selected port blinks in green to indicate that VCT is in progress.
The test is complete when the PORT SELECT (STATUS) LED stops blinking. Refer to page 9 for examples of VCT test results.
4.Press SEL to select another port to test. Follow steps 2 to 5 to run VCT.
5.When done, press the VCT button to return to normal switch operation.
NOTE. The switch automatically goes back to normal operation after two minutes even if you do not press the VCT button.
