I put a 1000BASE-T SFP (FS.com Extreme encoded) that usually works without hesitation in X450G2 switches in a new 5520 switch. This would be port 1:57.
I connected a cable to an ethernet handoff and get no link. sh port 1:57 does not show any link at all.
The reason I’m using this is to keep the face ports (1 to 48) free for endpoints and I was going to use the VIM-4X for uplinks.
Any reason why this module works fine on a 450G2 but not a 5520 on EXOS 31.1.3?
It sees it according to the log
Slot-1: Media 1000T is inserted into Port 1:57
I even tried a cisco one, it sees that one too according to the log, but I can’t establish a link.

You are best to follow up with your local Extreme SE. Have them reach into PLM. If you don’t know your SE you can DM me and I can help you out.

On this 5520 switch I get this:
Error: Auto negotiation off is not supported on port 1:57.
The other end is an MRV OS606 fiber to ethernet handoff from a WAN provider. I don’t have access to that config, the ISP handles that.
I tried plugging in my gigabit nic from my windows laptop to port 1:57 and it does not link up either.
Whats weird is the ISP supplied MRV OS606 device shows a link light when plugged into the EXOS 1:57 port. Its just the EXOS operating system is not signaling a link.

Check out the optics site for 5520 and the 1000BT p/n 10070H
https://optics.extremenetworks.com/EXOS/
It mentions that the extreme p/n 10070H is not supported on the VIM ports.
TTBOMK Its only supported on access ports for the 5520-48SE and 5520-24X.

Might be a chipset limitation that the 5520 does not support auto-nego on gigabit fiber-links - other EXOS Switches do support it and have it enabled on gigabit fiber-ports by default. Can you try to disable auto nego on both sides (or at least at the remote side):
