we have some different M4250 units and we have severe problems with them. Upon changing the assinged ports of a selected profile (eg. Dante and NDI Video) the ui hangs up, becomes unresponsive and the device quits all service.
We can only power off and power on again. Thus the settings cannot be applied.
We tried it from the OOB port, from other ports, from different VLANs – nothing. Always the same problem.
Very sorry to hear that. No, this is very surprising situation, I only saw it once or twice in the last two years - I believe some software corruption happened, and the only solution is going to be to factory-defaut (using the AV UI), and when the switch is default, re-install the latest firmware.
Please go to Maintenance \ Factory Default in the AV UI and click apply.
Please download the latest firmware (currently 13.0.2.34 below):
Please upgrade the switch with the .stk file from the zip archive file.
From there, please try to only the AV User Interface and let us know how it goes. You can always contact us by email at ProAVDesign@netgear.com and one of us will help you if the problem continues. If so, please send us the tech-support file out of the switch (AV UI go to Diagnostics \ Support Diagnostics, it will trigger the download of the file on your PC).
so we did try it on all three different models – the problems persist.
We installed the most recent firmware (13.0.2.34), set the devices back to factory defaults and reconfigured them manually. After that we tried to change profiles on different ports, which led to a hung up interface and the switch not responding anymore.
The only exception was when going over the OOB port. Through that we were able to change the configuration / profiles without a problem. Nevertheless we would like to be able to change the configuration without having to connect to that prot – because obviously they’re hidden inside our AV racks.
As a temporary solution we’re going to integrate a dedicated RJ45 jack in the racks for only the OOB port…
When back in the workshop I’ll be going to send you the diagnostic information.
Thank you for the update, and very sorry. We'll root cause that, be sure. Yes, please send us all tech-support files (the one from each switch) to us at ProAVDesign@netgear.com.
