Have you tried replacing the surge suppressor card with a new one? It might have taken a lightning hit and damaged some of the diodes.
You could switch to Chuck’s Cat6 version which is GDT (gas tube) only. Unlikely to get damaged, but might provide less protection, Chuck could probably speak to that.

A couple of months into their use the ethernet links to the radios on the tower start flapping and renegotiating down from 1G to 100M and then eventually 10M, and then eventually failing. When I bypass the card with a female-female RJ connector, they come right back up at 1Gig. These radios are powered from a MikroTik POE switch at 48v. Any suggestions? Am I using the wrong card for 48v poe? Thanks. -Brandon
