Cisco Catalyst C9300-48H-E at a Glance
The Cisco Catalyst C9300-48H-E is a 48-port Layer 3 switch built for high-density environments requiring robust Power over Ethernet (PoE) and scalability. Part of the Catalyst 9300 Series, it merges Cisco UPOE+ support with pre-loaded 5-year Cisco DNA Essentials licensing, targeting enterprises managing large-scale IoT, wireless, or smart-building deployments.
Technical Specifications: Power, Ports, and Performance
- Ports: 48 x 1G Base-T RJ45 ports (UPOE+/PoE+ capable) + 4 x 1G/10G SFP+ uplinks + 1 x modular slot (supports 25G/40G/100G modules).
- PoE Budget: 1.8 kW total PoE capacity (up to 90W per port), ideal for high-wattage devices like pan-tilt-zoom (PTZ) cameras, Wi-Fi 6E access points, and digital displays.
- Software: Includes Cisco DNA Essentials for 5 years, covering automation, monitoring, and threat detection out of the box.
Key Features Addressing High-Density Challenges
1. Universal PoE+ for Next-Gen Devices
The 48H-E supports Cisco UPOE+, delivering up to 90W per port—double the standard PoE+ limit. This eliminates the need for external power injectors in setups like smart offices or industrial IoT hubs.
2. Scalable Uplinks for Bandwidth-Intensive Workloads
The modular uplink slot allows upgrades to 25G, 40G, or 100G interfaces, ensuring seamless integration with high-speed data center or campus backbones.
3. Automated Network Operations
Pre-installed Cisco DNA Essentials enables zero-touch provisioning, application visibility, and predictive analytics, reducing manual configuration for overburdened IT teams.
C9300-48H-E vs. C9300-48T (Base 48-Port Model)
| Feature | C9300-48H-E | C9300-48T |
|---|---|---|
| PoE Budget | 1.8 kW (UPOE+) | 740W (Standard PoE+) |
| Licensing | 5-year DNA Essentials | 3-year optional license |
| Target Deployment | High-density IoT/edge | General-purpose campus |
Ideal Use Cases for the 48H-E
- Smart campuses deploying connected lighting, HVAC systems, and occupancy sensors across multiple floors.
- Healthcare networks powering PoE-enabled medical carts, patient monitors, and telemedicine kits.
- Retail environments unifying POS terminals, digital signage, and surveillance systems on a single infrastructure.

Why This Switch Redefines High-Density Economics
The C9300-48H-E’s 5-year licensing and UPOE+ cut long-term costs for enterprises managing sprawling IoT ecosystems. While its upfront price is higher than non-PoE models, the elimination of midspan injectors and license renewals simplifies budgeting. In practice, I’ve seen it excel in environments where power and port density directly impact operational continuity—like warehouses using autonomous robots. For organizations scaling smart infrastructure, the 48H-E isn’t just a switch; it’s a strategic enabler of future-ready connectivity.
