Hi Hrvoje,
Some intel Nics do have restrictions on what Trancievers they would
accept ... (like a licensing / branding thing ) ... if you are
ordering from fs.com or flexoptix you can re-program those with the
FS.com Tranciever programmer / Flexopticx Tranciever Programmmer...
for what it its worth ... I have come across weird issues with Ubnt
Edge switches and getting the SFP interfaces to come up ,..
where for instance in UBNT the autodetect, vs autonegotiate, vs 1000
Mb/s Full all have differenet results depending on the vendor of
router / device that is attached to the sfp interface...
I would play around with the combinations of autodetect (whcih is
different to auto negotiate) to forcing the speed...
your nic vendor may be able to provide you wiht firmware to unluck any
weird licensing restriction on the brand of tranciever in use...
I hope this is in some way helpful ... ?
if you use your phone camera can you confirm when the SFP is in the
Ix(4) interface... that the laser is on and is sending light ? (you
will see a purple / blue ish hue light on your camera of your phone...
)
Hope this helps and Happy new year to you ..
