Nexus fabric extender and pinned links

Hello, I recently went through the DCNIS-2 training course and got a ticket from a client stating that he had some trouble with a 2148T which failed and restarted. If I run the commands "show system reset reason" and "show diagnostic result fex xxx" I get that there was no real reason for restarting and that physically all ports are OK nonetheless when I issue the command "show fex detail xxx" I can't seem to locate ports in the range of 42 to 48.

Ok, when I said "I issue and I run the commands" I was trying to refer to our client which hasn't given me access to conifguration.

So the final question is... the ports that are not showing in the "show fex detail" could be part of some vPC? is there any explanation to this because port pinning is set to 1.
