MikroTik CRS518-16XS-2XQ-RM SFP no link -- not lighting up

Wed Apr 26, 2023 9:03 pm

Maybe I am missing something but I cannot get my 25G link from my ubiquiti switches to my mikrotik 25G ports.

I can see the microtik can see the SFP but I cannot get a link. Any help would be appreciated.

Here is my hardware/version info:

I have tried disabling auto-negotiation and set the link speed manually. No luck so far.
