ICX7150 Cable TDR Command State Analysis

[CHOIYOUNGJAE]

Hi, everyone.

TDR commands were used to inspect the entire network.

When I searched Google for materials related to RUCKUS, there was no clear answer, so I am contacting you

■ Inspection status

It is necessary to interpret the parts indicated in the red box in the above inspection conditions.

Basically, I know that it is normal if the cable distance is the same.

Open: RJ45 Bad Pin Contact
Short: Cable stuck together signal failure
Terminated: Connects successfully

1. Why do I see cable length information in 80-110M instead of 80M?

2. The reason why <=2M short is displayed is that a short occurred at the 2M point?

3. The reason why <=8M Open is displayed is because of the disconnection at the 8M point?

4. Why does Pair A display a question mark?

5. If PairA and D are 80-110M terminated, and PairB and C are 50-80M terminated, is the cable normal? If it is abnormal, why is it displayed like this?

I'm so frustrated whether I can't find the data or I don't have it.

Help me.
Thank you.

Hi Choiyoungae

From the description I see that you did mention RJ45 cable. Could you please let us know the category of the cable you are using in 1/1/12 , 1/1/4 and 1/1/6 also if you could help us with what devices they are connected to on 1/1/12, 1/1/4 and 1/1/6. 

Thanks

Chandini, hello!

All cables use CAT.5e and have APR 310 connected.

Please help me.
Thank you.
