Dell N2048, port disables when Open-Mesh A60 Access Point plugged in
I have a three N2048 stack. We purchased two Open Mesh A60 Access Points to replace some older HP APs. These Access points are PoE so we have injectors purchased through Open Mesh inline (after the switch inline to the AP). My issue is that when I plug in the Access Point(s) the Dell N2048 port goes active like it should, then after appx 20 seconds, the port goes off. I believe the N2048 is turning off the port for some reason but the RAM log only shows that it goes active then inactive.
Open Mesh support says that the AP's require Gratuitous ARP, but I don't see a setting for that anywhere in my N2048 and they don't offer any more support than that. I've tried messing with various changes in regards to RST, port-fast, enabling/disabling on the two ports where they were plugged in and it makes no difference.
I CAN plug the two APs into a dumb switch and then plug that into the N2048 and it works fine, so I figure it has to be something on the switch turning off the port. How can I figure this out?
Thank you,
Adam

Thanks for posting those logs up. Was hoping that it would provide a little information, but like you said, it just shows the port going down. I have seen some instances where devices are not able to negotiate speed and duplex for some reason. When manually setting the speed the connection suddenly works. Can you test manually setting the speed on the interface?

Version is 6.2.1.6, switch can not incur downtime, so it's not updated newer unfortunately
AP version is current, it's a brand new model
This is not the exact port that it was occurring on, because as of right now, I can't remove the AP's from active service to test but as I was watching the debug logging it's exactly what was happening, the messaging is the same. The switch detects that the port is active (when I reboot the PoE injector), then it fails about 20 seconds later.

What settings would turn off the port?

Can you share with us the messages seen in show logging? What firmware is the switch running? Sometimes firmware updates can help with interoperability. Are there any updates for the AP?

I have set one to 1000Mbps full and it works and the other to 100Mbps full. Sometimes they work when powered on and sometimes they don't.
I just received a reply from Open mesh that apparently there is an issue with the A60 AP and the Dell N2000 switches... I don't understand how that could be but I will wait for their reply.

Did you ever receive any type of response or come to any type of solutions? We have multiple N-series switches along with multiple A-series access points. We are having the same issues as you. Gateway to repeater mode back to gateway constantly. Have no access to the switches/firewall, but if you have any advice, I can gladly send it along to try to get this issue resolved.
