Determining the Estimated Distance To Fault (DTF)
To determine the estimate Distance To Fault (DTF), do the following:
1.
Connect a CAT-5 (or better quality) Ethernet cable with a known length to the device. Do not connect the
other end of the cable to another port.
2.
Configure the cable diagnostic utility to run a few times on the selected Ethernet port and start the test. For
more information, refer to
and recorded in the system log.
3.
Review the errors recorded in the system log and determine the average distance of the open faults. For more
information about the system log, refer to
4.
Subtract the average distance from the cable length to determine the calibration value.
5.
Configure the cable diagnostic utility to run a few times with the new calibration value. The distance to the
open fault should now be the same as the actual length of the cable. The Distance To Fault (DTF) is now
calibrated for the selected Ethernet port.
