I'm using a DELQA card to AUI connector, the board passes diagnostics without the loopback, but when I try to bring it up I get: Event type 5.14, Send failed Occurred 17-FEB-2023 22:15:05 on node 1.20 (TALOS) Line QNA-0 Failure reason = Collision detect check failed Is the connector for the DELQA different from the DEQNA? My other system has a DELQA with a DEQNA connector and it seems to work fine. I could put another DELQA in, but I want to see if these DEQNAs work. Or do I need to enable SQE on the AUI adapter?
