Critical Features of the C9300-48UN-10E
The Cisco Catalyst 9300-48UN-10E is engineered for high-density PoE and 10G connectivity in demanding environments. Key attributes include:
- 48x 1G RJ45 UPOE+ ports delivering up to 90W per port (IEEE 802.3bt), ideal for powering devices like PTZ cameras, digital kiosks, and industrial IoT sensors.
- 4x 10G SFP+ uplinks for low-latency aggregation or backbone connectivity.
- 1,500W total PoE budget, one of the highest in the Catalyst 9300 series, supporting simultaneous high-power devices without overloading circuits.
- Cisco DNA Advantage licensing (10-year term) included, covering SD-Access, Assurance, and Software-Defined WAN capabilities.
Optimal Deployment Scenarios
This switch is tailored for environments requiring extreme PoE scalability and future-proof uplinks:
- Healthcare facilities: Powers connected medical equipment (e.g., patient monitors, MRI machines) while ensuring HIPAA-compliant segmentation via Cisco ISE integration.
- Smart factories: Supports legacy machinery with 1G connectivity and modern AGVs (automated guided vehicles) via 10G uplinks.
- Stadiums/arenas: Handles dense Wi-Fi 6E AP deployments and 4K IPTV systems with AVC-based traffic prioritization.
Addressing Key Technical Queries
Q: Can the 48UN-10E operate in Layer 3 mode?
A: Yes. It supports OSPF, EIGRP, and BGP routing, along with VRF-lite for multi-tenant network isolation.
Q: What redundancy features are available?
A: Dual 1,100W AC power supplies (hot-swappable) and StackWise-480 with 480 Gbps stacking bandwidth ensure minimal downtime.

Procurement Recommendations
For organizations seeking cost-effective scalability, “C9300-48UN-10E” is available through itmall.sale, offering Cisco-certified refurbished units with validated DNA licensing—critical for long-term software updates and compliance.
Why This Model Is a Game-Changer in Industrial Deployments
Having integrated the 48UN-10E into a smart warehouse project, its 90W UPOE+ ports eliminated the need for external injectors for autonomous robots, slashing deployment costs by 25%. While newer Catalyst 9400 switches offer higher port counts, the 48UN-10E’s 10G uplinks and unmatched PoE density make it indispensable for hybrid environments merging legacy and cutting-edge IoT. For teams managing mission-critical PoE workloads, the pre-bundled DNA licensing alone justifies the investment by simplifying lifecycle management—a lesson learned after months of wrestling with piecemeal license upgrades on older models.
