M4250-26G4XF-PoE+ adding copper SFP
In an attempt to expand the port count of the switch, we have added two proper Netgear copper SFP modules. The switch recognizes them and show that they are supported. However, when an attempt to connect a device to the port, there is no connection established. At one point I was able to successfully connect a device and it had been working. The switch no longer wants to participate.
We have other modules here to test with as well and we get the same result. I have ruled out that it is a module issue because they shown as supported in the switch. I am under an impression that the firmware might have something to do with the behavior. I have not rolled back firmware yet but willing to do so.
Anyone one else have a similar experience? I know I am not alone because I have read many different threads online with the same type of complaint. Anyone found a solution?

Hello MaydmedoIT_69 and welcome to the Netgear Community.
Experiencing a similar issue on a smaller model, a M4250-8G2XF-PoE+ on an SFP+ slot accommodating an original Netgear AXM765v2 for many months.
Firmware Version
13.0.5.26 <-- same issue on earlier firmware version
AV UI Version
2.2.15.16
Boot Version
1.0.0.11
The slot #10 looks workable, initially allowed to be operated as the trunk. Everything looks correct. Had to switch the trunk to a 1 GbE port instead...
Fun fact? Another no-name module (1G/10G capable) in slot #9 connecting a local PC with a 1 GbE adapter on a 2 meter cable works flawless.
I know I am not alone because I have read many different threads online with the same type of complaint.
Have not spotted the related threads, admit I had not searched deep enough. Would you mind sharing some links please?

Sorry for not responding sooner as I don't log in frequently.
I see that you mentioned that a PC connected to the adapter worked flawless. I thought at one time I had the same result from my laptop adapter but that had been a few weeks prior and do not recall exactly what all I had done.
What I did discover is that a different device with a gigabit port would connect with no issue and maintained that connection without further issue. The parts that I found strange are that a Dante port of an amplifier would not connect but the connection with a Epiphan recording device would connect. The Dante port will be a gigabit connection and I assumed it would work(Iwas wrong) and works no problem on one of the other standard ports.
The compatibility of the device connected to the GBIC adapter is what is not completely understood. As a trunk port from one switch to another is understandable.
I do not recall exactly where I had read of some others experiencing the similar issue. I might have found threads on Redit.
