Description
Cisco Catalyst C9300-48UN Switch
Uniform Multigigabit Access | 48-Port 5G mGig | 60W Cisco UPOE | 480-Gbps Stacking
The Cisco Catalyst C9300-48UN is a premier, high-density stackable enterprise access switch purpose-built to future-proof campus networks for Wi-Fi 6, Wi-Fi 6E, and advanced IoT technologies. Unlike asymmetric layouts, this model features 48 uniform Multigigabit copper ports that all auto-negotiate line-rate speeds up to 5Gbps. Equipped with Cisco Universal PoE (UPOE) delivering up to 60W per port, the C9300-48UN cleanly supports high-power endpoints such as next-gen wireless access points, smart lighting systems, and corporate VDI terminals. Built on the proven UADP 2.0 architecture, it perfectly marries dense capacity with resilient Layer 3 routing capabilities and multi-layer edge security.
Key Technical Features
* Uniform 5G Multigigabit Density
All 48 copper ports feature multi-rate versatility, auto-negotiating speeds across 100M, 1G, 2.5G, and 5G to maximize Wi-Fi 6/6E client backplanes.
* 60W Cisco UPOE Capacity
All 48 copper ports supply up to 60W of power—double standard PoE+—to safely drive high-power IoT, advanced cameras, and multi-radio AP arrays.
* Cisco StackWise-480
Supports up to 480 Gbps of stacking bandwidth, enabling a resilient, single-logical-device architecture across up to 8 switches simultaneously.
* Flexible Modular Uplinks
Features a modular uplink slot accepting optional 1G, 10G, 25G, or 40G network modules to seamlessly scale your backbone connections.
* Advanced Perimeter Security
Utilizes Encrypted Traffic Analytics (ETA), AES-256 MACsec encryption, and TrustSec architectures to defend localized enterprise traffic lanes.
* Container Application Hosting
An onboard x86 CPU structure with 8GB RAM allows engineering teams to host lightweight native monitoring, management, or security containers.
