Got a couple of C9300X-24Y's with NM-2C's, Odd Interface Output

Hello all,

Recently got lucky enough to get my shipment of 9300X's after 7 months. Went to insert some QSFP-40G-LR4's, don't see any light. Ports are not shut. Also seeing in the running-config there are a number of ports that were never provisioned or configured there such as twe1/1/1-16, te1/1/1-8, and hu1/1/1-4. This is a 24 port switch with only a module with two 40/100 QSFP ports.

No matter what I do, I cannot get the ports to come up. I'm using SMF LC-LC connectors and I'm assuming the standard SMF cable is PC? Do I need to purchase LC (UPC) cables? I notice the cisco compatability matrix is now showing a difference between PC and UPC cabling.
