C9300-48UN-A Description

C9300-48UN-A combines high-density multigigabit UPOE access (48 ports at up to 5 Gbps/port) with a 256 Gbps non-blocking switching fabric. Each port delivers up to 60 W UPOE for Wi-Fi 6E APs, UHD cameras, and IoT endpoints. StackWise-480 provides 480 Gbps per switch (736 Gbps aggregated in an eight-member stack) with sub-50 ms fail-over. A modular uplink bay supports 1 Gb, 10 Gb, 25 Gb, or 40 Gb modules, protecting your core investment. Network Advantage unlocks full L3 routing, SD-Access micro-segmentation, Encrypted Traffic Analytics, and API programmability. Dual field-replaceable PSUs and fans ensure uninterrupted operation in busy campus or enterprise deployments.
