(I can’t find a more suitable forum, so just posting in the General one).
I have a Supermicro X11SPM-TPF-O motherboard, it has two SFP+ ports. I’ve installed the S-RJ01 (so that’s the the 1-gigabit version) into an SFP cage, but I can’t get connectivity. The machine is running proxmox linux, and it detects “eno1np0” and “eno2np1”
From the manual:
“X11SPM-TPF Only: Inphi CS4227 for 10G SFP+ Ports”
Is there any way of knowing if these two are compatible? Maybe only a S-RJ10 (10gbit version) would work?
Any commands I can run to see the status of the device?
I’ve never had the chance to use this specific variant, but we did use the copper version (X11SPM-TF) for a while, which had a possibly related behavior quirk: you could run them no slower than 1G. If you accidentally plugged them into a 100M port, it wouldn’t even give you a link light.
I realize you’re trying to get 1G, but that experience makes me suspect the fiber version is 10G-only.
As for the “S-RJ10 (10gbit version),” I believe you mean the S+RJ10, a notoriously hot module, allegedly owing to its super-flexible 6-speed design. There’s no especially good reason to run that in a Supermicro mobo. I’d select a single or dual-speed generic matching the speed you actually need.
(Dual = 10G plus either 1, 2.5, or 5G, depending on your local legacy/interim tech needs.)
