update: bought some pre-done usb 2.0mm header to 2.54mm header and they work, got into bios and can no actually use it as a computer....wooo
bought a mellanox branded dac as thats listed as compatable, loaded up a sata hdd with linux on it, but the nic doesnt show.
which jumper was the one that disabled it? mine may be lablelled differently? as its not showing up, annoyingly.
get nothing from BMC, prob going to flash that generic one and see if it works. not losing anything if it doesnt, tbh
The ports that can be disabled by jumper are the 'extra' Mellanox ones on the -IBQ- model not present on the storage node.
I have a generic intel-compatible dac from fs.com and it worked. Did you bring up the interface with 'ip link set dev xxxx up' ? Ubuntu didn't see anything connected until I did that - after that step ethtool showed a dac connected to the interface.
So far I only tested the 2nd SFP28 port, but this weekend I can test the first port (that is present on your model) as well.
Edit: if lspci / dmesg doesn't show the mellanox device, I'd have another look in the BIOS. Maybe there's an option to disable it somewhere. I'll also look for jumpers when I'm back home again, but I don't recall seeing one for that port.
Edit2: another suggestion is to try booting with the BMC jumper set to disabled - if you get stuck at bios check 99 like me, you probably don't want to risk bricking the BMC by flashing different firmware. Another thing to check is how big a firmware can be flashed - is there enough room for a 'fully featured' bmc firmware?
Edit3: reminder to self, i need to check ip access control for ports 80 and 443 on the bmc that the license should have unlocked.
