ANT-4-5G4-O=: How Does This Cisco Antenna Opt
Core Technical Specifications and Design The ANT-...
Key Features and Hardware Design
The Cisco Catalyst C9300-48U-E-UL= is a 48-port Universal PoE (UPoE) switch engineered for environments demanding high-power device support. Unlike standard PoE models, the “48U-E-UL” designation confirms UL (Underwriters Laboratories) certification for safety and compliance, critical for industrial or enterprise settings. Its 740W power supply delivers up to 90W per port (IEEE 802.3bt), accommodating devices like PTZ cameras, digital signage, and high-performance Wi-Fi 6/6E access points.
Core specifications include:
- 48x 1G/2.5G/5G/10G multi-gigabit RJ45 ports, backward-compatible with legacy devices.
- StackWise-480 support, allowing 8-unit stacking with up to 480 Gbps bandwidth for seamless scalability.
- EnergyWise integration, enabling dynamic power allocation based on real-time demands.
Addressing Universal PoE and Safety Concerns
A frequent query is: “Does the C9300-48U-E-UL= prevent overloads in high-density deployments?” The switch employs Smart Power Monitoring, which allocates power per port while prioritizing critical devices. Its UL certification ensures compliance with stringent fire and electrical safety standards, a key requirement for healthcare, manufacturing, or educational campuses.
Another concern centers on scalability. The Cisco DNA Software subscription (Advantage or Essentials) provides Predictive StackWise failover and AI-driven power optimization, reducing manual adjustments as networks grow.
License Flexibility and Total Cost of Ownership
While the base hardware excels in power delivery, Cisco DNA Advantage licensing unlocks features like Application Visibility and Control (AVC) and encrypted traffic analytics. Unlike competitors with rigid licensing, Cisco’s pay-as-you-grow model aligns costs with deployment phases.
Ideal Use Cases and Procurement Options
This switch thrives in:
- High-density workspaces with mixed-device ecosystems (e.g., collaborative AV systems).
- Industrial IoT hubs requiring reliable power for sensors and machinery.
- Smart buildings integrating lighting, HVAC, and security systems over a single network.

Final Observations
Having worked with PoE switches across industries, the C9300-48U-E-UL=’s blend of power precision and compliance sets it apart. While similar models offer high wattage, this switch’s UL certification and Cisco’s zero-trust integration eliminate trade-offs between performance and safety—a critical advantage for risk-averse IT leaders planning future-ready infrastructure.
