Hello,
i have installed SG300-10SFP switch in one customer site, port g1-g9 is for customers and g10 for uplink to Metropolitan network
after installation, all working fine, in port g10 i have installed SFP CWDM with DDI (diagnostics) all data like Temp, signal etc... switch displays correctly, after 60days i can check DDI info, but now switch displays only "N/A" value
i can try reboot, but same value in WEB or CLI, in port status is all OK port is connected
i have firmware
1.3.5.58
