The C9300 switch didn't exist when table 2 in that spec sheet for the 3850 was written. So, none of the 9300 compatible parts are listed. We just tested a C9300-NM-4G here and it  worked fine in a 3850. Maybe the C9300-NM-8X does too?

I performed this test with a WS-C3750 running c3750-ipbasek9-mz.122-55.SE12.bin. Both times as a standalone switch once with switch priority 1 next with priority 15, ~2:58 each time.

This worked for me except for the part "create part primary size=4000". I tried different sizes until it to worked. create part primary size=3900create part primary size=3800create part primary size=3700 The "create part primary size=3700" worked for...

As a side note the AB switch is actually a rebranded Cisco Industrial Switch. You can wipe it and manage it like any Cisco switch without the Allen Bradley GUI.
