C9300-48H-A Description

C9300-48H-A delivers forty-eight 1 Gb UPOE+ ports with up to 90 W per port over a 256 Gbps non-blocking switching fabric. Four hot-swap Type-1 uplink bays support any combination of 1 Gb, 10 Gb, 25 Gb, or 40 Gb modules. StackWise-480 offers 480 Gbps per switch and up to 736 Gbps across an eight-switch stack with sub-50 ms fail-over. Network Advantage unlocks full Layer 3 routing, SD-Access segmentation, Encrypted Traffic Analytics, and API programmability for automated campus fabrics. Dual 1100 W AC power supplies yield up to 720 W of PoE budget, while redundant, field-replaceable fans maintain always-on cooling.
