Only the cc0 port is connected to the switch, but none of the ports have detected a carrier. I tried swapping the fiber strands to no avail. For some reason, I was unable to select 10 Gbit/s using ifconfig cc0 media 10Gbase‑SR. I’m waiting for some SFP⁺ modules to arrive, maybe they can connect to the switch.

BTW. The Gutenberg Editor for WordPress is a nightmare in conjunction with the SyntaxHighlighter plugin. I went back to the Classic Editor which gives me far more control.
