Hi everyone,

I use two modules SM5310-T v 1.2 with two indentical omada switch SG3428XMP v3.20. between module and patchpanel CAT 6 UTP 0,25m cable, lenght of CAT6A FTP cable 40meters. Same on both side. After some time o cannot acces to my controler thru this line. When i try internet speed it is only 1Mbit/s (standart 250Mbit/s). When i try to connect to OC200 directly speed and everything is ok? I dont know if I something wrong setup? Or where can be a problem?

UPDATE: It looks there is problem between two modules. If I do not use module on one side and put patch kabel tu trunk port 24 on switch it is working without problem.

Anyone help please?

Thanks for answer
