I have MCX341A-XCEN and MCX342A-XCCN ( both Mellanox Connectx-3 NICs ) connected directly through SFP+ cable but both I/O LED doesn’t lit up.
However, if I connect between two MCX341A-XCEN using the same cable, both I/O LED do lit up.
Same goes for connect between two MCX342A-XCCN.
I notice the firmware version for MCX342A-XCCN is 2.42.5000, while MCX341A-XCEN version is 2.31.1598. I have tried to upgrade both cards to the same firmware version ( 2.42.5000 ) from the firmware download site. But I can’t find the same matching PSID firmware for MCX341A in version 2.42.5000
