Cable Diagnostics Notes
1. The following two conditions apply for ports 9 and 10 on the DGS-3200-10, for ports 13, 14, 15, and 16 on the
DGS-3200-16, and ports 25, 26, 27, and 28 on the DGS-3200-24: crosstalk errors cannot be recognized and the length
cannot be obtained when the port is connected to a 1000Mbytes port which is either forced to 10/100Mbytes or powered
down.
2. If cable length is displayed as "NA," this means the cable length is "Not Available".
3. The cable length cannot exceed 80 meters if the port is connected to a powered-off device or to a port which is configured to
force 10/100Mbytes speed.
4. Accurate measurement cannot be obtained when the cable is shorter than 1 meter.
5. The error deviation is +/-5 meters in length.
6. Cable fault is measured and the fault length is identified according to the distance from the switch.
