Anybody using cat 7A (Tera) cabling with 3850 ports ?

Observing some ports with PoE+ splitters (Class 4 devices) continuously giving power TStart errors.

Issue doesn't happen when i drop a Cat 6A UTP cable between the splitter and the port as a test.  The structured cabling is certified Cat 7A (on TE) with factory TE cables (Hybrid: Tera / RJ45 ends).

Additionally, we have some Axis PTZ cameras (class 4) working fine off the same cabling.  Plenty of Class 3 devices (9971 IP Phones etc) work a treat.
