Hi everyone
I’m facing a strange issue and would like to ask for your advice. When I plug the SFP (fiber) module into the switch, all cameras and NVRs lose connection and there’s no signal at all. However, when I completely remove the SFP module from the fiber port, all cameras and NVRs immediately come back online.
Has anyone ever encountered this situation before? What could be the cause, and how can it be fixed? I’d really appreciate any suggestions or insights. Thanks
