Cisco C9500-48Y4C-A 48-Port SFP28 Core Switch

C9500-48Y4C-A Overview
Forty-eight fiber connections with a separate uplink block
This configuration provides twice the SFP28 port count of the 24Y4C while retaining four 40/100G uplinks. Evaluate the intended aggregation traffic and selected optics before allocating the ports; a common family name does not make the two chassis configurations identical.
Power resilience needs a second supply
The platform supports dual 1+1 power supplies, but Cisco states that a single supply ships by default. Verify the installed second supply when redundancy is required. The supported matrix includes C9K-PWR-650WAC-R, C9K-PWR-650WACL-R and C9K-PWR-930WDC-R; select against the actual rack power source rather than assuming AC and DC units are interchangeable on the order.
Keep core features distinct from access-switch stacking
StackWise Virtual is the applicable architecture, not StackWise-160. The 48Y4C does not accept C9500-NM-8X or C9500-NM-2Q modules. Network Advantage identifies the software tier, while subscription duration and support coverage require separate confirmation. Cisco rates forwarding up to 1 Bpps and qualifies switching line rate for packet sizes of at least 187 bytes.
