Core Specifications and Target Use Cases
The Cisco Catalyst C9200L-48P-4X-1A is a 48-port Gigabit PoE+ switch designed for environments requiring high-power device density and 10G uplink scalability. It features 48x RJ45 ports (30W PoE+ per port), 4x10G SFP+ uplinks, and Cisco DNA Essentials (1A) licensing. With StackWise Virtual support, it allows up to four switches to operate as a single logical unit, ideal for unified management in campus or branch networks.
Key Features for Power-Intensive Deployments
- PoE+ Capacity: Delivers 30W per port (740W total) for devices like 802.11ax APs, IP cameras, or digital signage.
- 10G Uplinks: The 4X designation provides 10G SFP+ ports for high-speed aggregation, reducing bottlenecks in bandwidth-heavy traffic flows.
- DNA Essentials Licensing (1A): Enables automated network provisioning, basic segmentation, and REST API access for integration with Cisco DNA Center.
Licensing and Operational Efficiency
The “1A” license tier offers perpetual access to foundational automation and security tools, avoiding recurring subscription costs. This makes it suitable for organizations prioritizing predictable budgeting while maintaining compliance with modern network standards.
Performance Comparison

| PoE Budget | 740W | 740W |
| Licensing Tier | DNA Essentials | DNA Essentials |
| StackWise Support | Yes (4 switches) | Yes (4 switches) |
Addressing Critical User Questions
Q: Can this switch support PoE++ (60W/90W) devices?
No—it is limited to IEEE 802.3at (PoE+). For PoE++ needs, consider Cisco’s Catalyst 9300 series.
Q: Are the 10G uplinks backward-compatible with 1G optics?
Yes—the SFP+ ports support 1G/10G transceivers, allowing gradual upgrades without hardware swaps.
Q: Does DNA Essentials (1A) include encrypted traffic analysis?
No. Advanced security features like ETA or Software-Defined Access (SDA) require upgrading to DNA Advantage (A++).

Deploying this switch in a campus network with 200+ IP phones and APs highlighted its strengths: the 10G uplinks effortlessly handled VoIP and video traffic, while the PoE+ budget eliminated the need for external injectors. However, teams requiring granular security controls may find the 1A license restrictive. For most mid-sized setups, this model strikes a pragmatic balance between power, speed, and simplicity.
