After installing the fiber NIC, it cannot communicate after using the fiber module. Why?

Date:2023-03-16Views:1015Tags:
Question: After installing the network card and driver normally, it can be recognized normally, but the fiber module cannot communicate, what's the matter?

Answer: This phenomenon can generally be checked through several aspects.

1. Troubleshoot network card problems, the ability to install the network card driver is basically troubleshooting the network card failure;

2. Check whether the fiber module is plugged in place. If it is not plugged in place, the network card side or switch side will think that the fiber module is not inserted;

3. Check whether the switch supports the speed of the network card and fiber module;

4. Check whether the fiber modules of the same brand and model are used at both ends; generally such as Huawei optical fiber modules have requirements in this regard.

If the problem still cannot be solved after the above inspection steps, please consult technical personnel.
