Cable Diagnostics Notes
1. The following two co nditions app ly fo r ports 9 and 10 on th e DGS-320 0-10, for ports 13, 14, 15 , an d 16 on the
DGS-3200-16, and ports 25 , 26 , 27 , an d 28 on th e DGS-3200-24: cr osstalk err ors can not be recognized and th e length
cannot be obtained when the port is conn ected to a 1000Mbytes port which is eith er fo rced to 10/100Mbytes or pow ered
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.
