date 11/8/2018, I just ordered JL083a (4 port ) 10 gig SFP card to install into the HP Aruba 2930M. Upon adding expansion card shutdown power instlled and reboot. As you say and I see; the card is not being found in the show run command.
i did >show run,>show int br, >erase startup-config, >show module and its still not seeing card and firmware is old like your notes #WC.16.04.0004 and I seen a new firmware 16.004.008. I have not tried to update firmware yet.
basically was hoping plug and play like the 4 smart-card
