Core Capabilities of the Cisco C9300-48UN-A=
The Cisco Catalyst 9300-48UN-A= is a 48-port UPOE+ (Universal Power over Ethernet) switch engineered for high-density deployments requiring multi-gigabit speeds and industrial-grade power delivery. Unlike standard PoE switches, it provides 90W per port across all 48 ports, totaling a 3,460W PoE budget—ideal for demanding environments like smart factories, large-scale IoT deployments, and advanced wireless networks. Key features include Cisco StackWise-480 for seamless stacking (up to 480 Gbps bandwidth) and IOS XE Software for unified automation via Cisco DNA Center.
Hardware and Performance Specifications
- Port Configuration: 48 x UPOE+ RJ-45 ports (1/2.5/5/10Gbps auto-negotiation) + 4 x modular uplink slots (supports 10G/25G/40G/100G modules).
- Switching Capacity: 1.44 Tbps (non-blocking).
- Forwarding Rate: 1.08 Bpps.
- Power Supply: 2200W AC (hot-swappable, N+1 redundancy).
- Security: MACsec-256 encryption, Cisco TrustSec for microsegmentation, and Cisco Cyber Vision for OT/IoT threat detection.
The switch supports Application Hosting, enabling on-device deployment of containerized apps like network analytics tools, reducing reliance on external servers.
Key Use Cases and Deployment Scenarios
- Industrial IoT: Powers robotic arms, AGVs (Automated Guided Vehicles), and PLC systems with <1ms latency.
- High-density Wi-Fi 7: Delivers 90W to 802.11be access points while supporting multi-gig backhaul.
- Smart retail: Connects 4K digital signage, AI-powered inventory systems, and POS terminals with uninterrupted PoE.
Its modular uplinks allow cost-effective scaling to 100G, making it suitable for spine-leaf architectures in large campuses or data centers.
Licensing and Software Integration
- Cisco DNA Essentials: Basic automation and monitoring.
- Cisco DNA Advantage: Unlocks AI-driven insights, SD-WAN integration, and Predictive NetOps for proactive issue resolution.
- Cisco ThousandEyes: Provides end-to-end visibility for hybrid WAN performance.
Competitive Advantages Over Alternatives
- Unmatched PoE Density: Competing switches (e.g., Aruba 8400) max out at 30W per port, forcing power-sharing and risking device downtime.
- Future-Ready Port Speeds: Native 10G multi-gig ports eliminate the need for costly mid-life upgrades to support Wi-Fi 7 or 25G uplinks.
- Unified Management: Cisco DNA Center integration simplifies operations across wired, wireless, and SD-WAN domains.
