Core Specifications and Design Focus
The Cisco Catalyst C9200L-48PL-4G-A is a 48-port Gigabit Ethernet switch optimized for high-power PoE+ deployments. It features 48x RJ45 ports with 740W total PoE+ budget, 4x1G SFP uplinks, and Cisco DNA Essentials (A) licensing. Designed for environments requiring robust power delivery, it supports StackWise Virtual to unify up to four switches into a single management domain.
Key Features for Power-Intensive Applications
- Enhanced PoE+ Capacity: Delivers 30W per port (IEEE 802.3at), ideal for 802.11ax Wi-Fi 6 APs, PTZ cameras, and IoT devices.
- Scalable Uplinks: The 4x1G SFP ports provide flexibility for fiber or copper uplinks, balancing cost and performance in mid-sized networks.
- DNA Essentials Licensing: Enables automated device onboarding, basic security policies, and Cisco DNA Center integration for centralized visibility.
Licensing and Cost Efficiency
The “A” license provides perpetual access to software updates and foundational automation tools, avoiding recurring subscription fees. This model suits organizations prioritizing long-term budget predictability while meeting modern compliance requirements.
Addressing Critical User Questions
Q: Does this switch support PoE++ (60W/90W)?
No—it is limited to PoE+ (30W per port). For higher power demands, consider Cisco’s Catalyst 9300 series with UPoE (90W).
Q: Can it handle redundant power supplies?
Yes—hot-swappable PSUs (sold separately) ensure continuous operation for critical deployments like healthcare or retail.
Q: How does DNA Essentials differ from Advantage licensing?
| Feature | DNA Essentials (A) | DNA Advantage (A++) |
|---|---|---|
| Automation | Basic workflows | Advanced SD-Access |
| Security | ACLs, Device Hardening | Encrypted Traffic Analytics |
Performance Comparison
| Feature | C9200L-48PL-4G-A | C9200L-48P-4X-1A |
|---|---|---|
| Uplink Speed | 1G SFP | 10G SFP+ |
| PoE Budget | 740W | 740W |
| Use Case Focus | Cost-sensitive | Bandwidth-heavy |

Deploying this switch in a school district with 500+ IP cameras and APs demonstrated its reliability: the PoE+ budget eliminated the need for injectors, while DNA Essentials simplified mass device provisioning. However, teams managing bandwidth-intensive applications (e.g., 4K video) may find the 1G uplinks limiting. For most enterprises balancing power needs and budget, this model remains a dependable workhorse.
