Hello,

Our customer is facing an issue when connecting the switches using the copper cable.

If we install S6730 back to back along with the 40G copper cable, the interface will up and traffic can forward normally, instead, when connecting 40G SFP module into CE12800 40G interface, the interface does not turn up.

Please, kindly help to confirm is this normal? Or shall we do some asjustment to make the interface up.

Thanks.

Posted by user_3445655 at 2020-02-25 09:49 Kindly thanks for your help.We tried both, both Huawei and non-Huawei copper cable.
Hi,
When using non-Huawei copper cable, we are not able to help.
For Huawei copper cable, when used for data transmission between service ports, copper cables can only connect Huawei switches of the same subseries. These copper cables cannot be used between Huawei switches of different subseries or between Huawei switches and other devices such as PCs, hosts, servers, or routers.
So, it’s normal, it’s not allowed to use the copper cable for data transmission between different subseries switches.

Hi @tesfama,
Exactly, for S9300, the copper cable only can be used to connect another S modular switch.
