Power Supply Compatibility

[CMack6]

Hello,

I am wondering if my old C3KX-PWR-350WAC PSU will work in my new C9300 switches.  

Thanks!

PWR-C1-1100WAC-P
PWR-C1-1100WAC-P
PWR-C1-1900WAC-P

This is an "unofficial" universal power supply that is compatible with the 3750E/X, 3850 and 9300. 

Starting with the 9300 the same power supply (and other sub-model with different power ratings) have been "re-designated" (or "re-numbered") as "PWR-C1-nnnnWAC-P" (where "n" is the power rating).

Either SKU/PID is the same and is compatible.
