We are building a new 8.2.1 Cluster-Mode cluster with two FAS3250's.
We have connected c0a on FAS1 to c0a on FAS2 annd c0b on FAS1 to c0b on FAS2 but get no link-light and thus HA failover is not working.
I replaced cables and SFP's. I've tried straight-through and crossed fiber cables.
I've also tried connecting c0a to c0b on FAS1 to see if I get a link light and I don't. Repeated on FAS2 and same result.
It's looking like a software misconfiguration rather than hardware. Any suggestions gratefully received. 🙂

Solved ourselves. We were using the wrong speed SFP's. They have to be 10Gb.
