Product overview
WS-C3850-12XS-S is the IP Base (-S) 12-port 10G SFP+ Catalyst 3850 aggregation PID. It lists 320 Gbps, 227.28 Mpps, Non-PoE, PWR-C1-350WAC, and modular uplink options (C3850-NM-4-1G or C3850-NM-2-10G).
Use it when the design needs IP Base rather than IP Services (-E). See WS-C3850-12XS-E when IP Services is required.

3850 stacks that standardize on -S feature set.
Technical selection notes
Do not mix -S and -E assumptions in one stack without checking. Name the NM on the RFQ.
Not recommended for
Not an IP Services (-E) PID — use WS-C3850-12XS-E when -E is required.
Not a PoE copper access switch.
