Possibly a faulty card.


I'm guessing by card you mean the optic? These are QSFP28 ports.

Clean fiber as Daniel mentioned, reseat optic, the usual stuff. Try
replacement parts you have in stock, then go from there replacing the
cheapest components first before trying to replace the more costly ones.

What manufacturer optic are you using, and what sort of media specifically?
