Hey, we recently had our first customer shipment of C9300L-M switches and I was surprised that the accessories inside the box are different than the C9300 switches you get in normal Cisco designs.
The regular kit has the two rack ears, a cable holder, a power cable!!!, and blank plates on the back where you screw in the stacking modules.
I found that the -M switch has a lot of "airflow" by default. the backside is completely open, there are even holes where you can optionally insert the stacking modules. Meaning if you use it for an individual switch you have 2 gaping holes in the back of the switch. You do get the plate to cover up the secondary psu slot if you don't get the secondary psu.
Personally I find this confusing why there is a difference in the kit and will cause headaches to have a correct BOM for projects.
