Ports dying when connected to QNAP switch
I've got a Netgear JGS524PE switch which is behaving weirdly. I have a 2.5Gb QNAP switch which I'm attaching to it. Every port I attach it to it seems to kill the port. Same wall socket I can connect to with a laptop and it works fine but as soon as I plug in the QNAP switch then nothing. And if I plug the laptop in again afterwards then nothing as if the port has been killed.
I can run a long cable to another wall socket and the QNAP switch works fine. Is there anywhere I can find more information about what is going on and perhaps re-enable the ports?
- This turned out to be a fault with the module in the faceplate that wasn't picked up by my original tester. I got a more advanced one and it became clear. Swapped the module and it works fine.

Somehow causing loops where STP/RSTP/MTP or hardware loop detection methods are causing loops? This could disable a port. For example on mis-configured LACP on multi-link connections.
Which QNAP switch model (firmware, configuration, ...) do you have in mind?
- The QNAP switch is a QSW-1105-5T. I'm not sure on the firmware as it's not a managed switch so it doesn't have an IP address that I can see and therefore no web console.
The router only has 3 ports utilised. 1 to a server, 1 to a QNAP TS-635D NAS device and the last is to the wall port. The only strange thing about the cable from the port to the Netgear switch is that it has a coupler in the middle.
The managed switch is operating on a vanilla configuration with nothing changed apart from it's IP address. I performed a factory reset to see if it would re-enable the ports, which it did not.
It was working fine elsewhere in the building and also fine on the other socket so I believe it's something about this cable run which is odd.
So the two issues I have to solve are how to re-enable the ports which have stopped working and the issue that is causing them to be disabled in the first place
