C9300-48P-A: What Are Its Core PoE+ Capabilities, How Does It Compare to Non-PoE Models, and Why Choose It for High-Density Deployments?



Core Features of the C9300-48P-A: Powering Modern Enterprise Networks

The ​​Cisco Catalyst C9300-48P-A​​ is a ​​48-port PoE+ Layer 3 switch​​ designed for environments demanding high-density Power over Ethernet (PoE) support. With a ​​740W power budget​​, it delivers ​​30W per port​​ (802.3at PoE+), making it ideal for IoT hubs, wireless access point clusters, and IP phone systems. Integrated ​​Cisco DNA Essentials​​ licensing enables automated network policies, while ​​StackWise-480​​ allows stacking of up to eight switches for unified management.

​Key strengths​​:

  • ​48x Gigabit RJ45 ports​​ with full PoE+ support.
  • ​Four modular uplink slots​​ for 1G/10G/25G scalability.
  • ​Energy-efficient design​​ with sub-150W idle consumption.

Performance Comparison: C9300-48P-A vs. Non-PoE and Fiber Models

This switch excels in scenarios where power delivery and port density are critical. Below is a comparison with the C9300-48H-1E (non-PoE) and C9300-24S-1E (fiber):

​Feature​ ​C9300-48P-A​ ​C9300-48H-1E​ ​C9300-24S-1E​
PoE Budget 740W (30W per port) N/A N/A
Port Density 48x PoE+ RJ45 48x non-PoE RJ45 24x 1G SFP
Target Use Case High-density Wi-Fi 6/6E, VoIP Data center core aggregation Fiber-based backbone networks

Addressing Critical User Concerns

​Q: Can the 740W PSU handle all 48 ports at full PoE+ load?​
A: No. The switch prioritizes power allocation dynamically, supporting ​​up to 24 ports at 30W​​ simultaneously. For full 48-port utilization, reduce per-port power or mix PoE/PoE+ devices.

​Q: Is redundant power available?​
A: Yes. The switch supports ​​dual 715W AC or DC power supplies​​ (sold separately) for mission-critical uptime.

​Q: What’s included in DNA Essentials licensing?​
A: It covers ​​automated QoS​​, ​​basic threat detection​​, and ​​Cisco SD-Access​​ for network segmentation. For advanced features like encrypted traffic analytics, upgrade to DNA Advantage.

​Q: How does StackWise-480 improve scalability?​
A: It creates a ​​single management domain​​ across stacked switches, reducing configuration complexity and enabling hitless failover. For procurement, visit the [“C9300-48P-A” link to (https://itmall.sale/product-category/cisco/).


Real-World Perspective: Where This Switch Proves Its Worth

In a recent hotel chain deployment, the 48P-A’s ​​PoE+ density​​ eliminated the need for external injectors across 500+ IP phones and 200 Wi-Fi 6 APs, slashing installation costs by 35%. While the 48H-1E suits data-heavy cores, and the 24S-1E excels in fiber backbones, the 48P-A dominates in edge environments where power and ports are non-negotiable. Its ​​modular uplinks​​ also future-proof investments—deploy 10G today, upgrade to 25G later without replacing hardware. For IT teams juggling budget and scalability, this switch strikes a rare balance between brute-force utility and strategic flexibility.
