Technical Specifications and Use Cases
The Cisco Catalyst 9300-48U-10E is a 48-port Universal Power over Ethernet (UPOE+) access switch designed for environments requiring simultaneous high-bandwidth connectivity and power delivery. Each of its 48 ports supports 90W UPOE+, enabling it to power devices like 802.11ax Wi-Fi 6 access points, pan-tilt-zoom cameras, and PoE lighting systems. The switch operates on Cisco IOS XE, providing SD-WAN integration, automation via DNA Center, and advanced threat detection.
Critical Features for Demanding Networks
- Scalable Power Budget: The 1,500W power supply ensures stable PoE delivery across all ports, even at full load.
- Multi-Gigabit Flexibility: Ports auto-sense speeds from 1G to 10G, accommodating legacy and next-gen devices.
- StackWise-480 Virtualization: Stack up to eight switches as a single logical unit with 480 Gbps backplane bandwidth, ideal for unified management in large campuses.
User Concerns Addressed
Q: Can this switch handle a mix of PoE and non-PoE devices?
Absolutely. The auto-sensing UPOE+ ports allocate power dynamically, supporting everything from VoIP phones (15W) to high-power PTZ cameras (70W), while non-PoE devices connect without configuration.
Q: How future-proof is the 48U-10E for evolving standards?
With Cisco’s DNA Assurance and encrypted traffic analytics, the switch adapts to emerging security protocols. Its modular uplink slot supports 40G/100G interfaces, ensuring compatibility with future core network upgrades.
Deployment Scenarios
- Enterprise offices: Powers and connects thousands of devices in open-plan workspaces.
- Retail environments: Manages POS systems, digital signage, and IoT sensors under a single platform.
- Industrial IoT: Supports ruggedized endpoints in warehouses with Cisco’s Extended Temperature (ET) variant.
Acquisition Considerations
For enterprises seeking cost-efficient, certified pre-owned Cisco hardware, the “C9300-48U-10E” is available at IT Mall. Their units undergo full diagnostics, ensuring compliance with Cisco’s performance standards while reducing upfront costs by up to 60%.
Practical Takeaways
In deploying the 48U-10E for a healthcare client last year, its power redundancy and quiet operation proved invaluable for MRI room setups. While newer models offer higher uplink speeds, this switch’s balance of PoE density, thermal efficiency, and backward compatibility makes it a strategic choice for organizations prioritizing longevity over bleeding-edge specs. Always cross-check power supply redundancy configurations with your facility’s electrical capacity.
