Description
Cisco Catalyst C9300-24UB Switch
Higher-Scale & Deep Buffer Access | 24-Port Gigabit UPOE (60W) | 32MB Buffer | 480-Gbps Stacking
The Cisco Catalyst C9300-24UB is a premium, higher-scale stackable access platform engineered for high-density enterprise routing and mission-critical network edges. Driven by the enhanced UADP 2.0 XL ASIC, this deep-buffer model doubles the standard packet buffer complex to 32 MB, massively expanding MAC address tables, ACL thresholds, and IP routing scale to eradicate drops during sudden traffic bursts. Outfitted with 24 fixed Gigabit ports pushing up to **60W Cisco Universal PoE (UPOE)**, it powers demanding IoT nodes, corporate wireless infrastructures, and VDI complexes while keeping core backplane environments entirely stable.
Key Technical Features
* 32MB Deep Packet Buffer
Powered by the UADP 2.0 XL ASIC to supply twice the buffer size of standard 9300 units, keeping video, voice, and data streams fluid under load.
* 60W Cisco UPOE Capacity
Delivers up to 60W of power per port—double standard PoE+ caps—backed by an 830W default power budget to sustain high-wattage hardware arrays.
* Stacking Constraints Warning
Supports up to 480 Gbps of stacking bandwidth. Note: Higher-scale "B" switches stack exclusively with other deep-buffer models (e.g., C9300-48UB).
* Modular Uplink Versatility
Features a modular network module bay accommodating optional 1G, 10G, 25G, or 40G uplinks to easily adapt as core demands grow.
* Advanced Perimeter Security
Utilizes Encrypted Traffic Analytics (ETA), AES-256 MACsec encryption, and TrustSec architectures to defend high-volume localized data flows.
* StackPower Resiliency
Incorporate Cisco StackPower to pool and share power supplies across your switch stack, ensuring absolute hardware availability if a unit PSU fails.
