C9300-48U-A Description

C9300-48U Front
C9300-48U-Rear
Cisco Catalyst C9300-48U-A delivers pervasive 60 W UPOE power across 48 access ports while providing a non-blocking 256 Gbps switching fabric and advanced Network Advantage services. The hot-swap Type-1 module bay supports 1/10/25/40 G uplinks, safeguarding edge investments as backbone speeds evolve. StackWise-480 aggregates up to eight switches under a single control plane, and StackPower pools spare wattage across the ring for resilient power. With Secure Boot, MACsec-256, ETA analytics and full Layer 3 routing, C9300-48U-A is engineered for zero-trust smart-building and high-density campus deployments.
