I have two Nexus 9372PX's and just purchased two FEX C2348TQ's. When I attempt to configure a Nexus for a FEX I'm receiving the following output from the show fex detail command:

Now, I realize that I probably need to upgrade the parent Nexus to get it to work, however the latest stable version of NX-OS is 7.0(3)I2(2d). As far as I can tell there isn't a 7.1 version of NX-OS available for my Nexus switches. I'm not sure what I should do at this point other than open a ticket with Cisco. Anyone have any ideas?
FWIW, here is my configuration for these FEX switches:
