What Is the Cisco C9200L-24T-4G-1A?
The Cisco C9200L-24T-4G-1A is a non-PoE Catalyst 9200L Series switch optimized for enterprise access and distribution layers requiring high-speed connectivity without Power over Ethernet (PoE) demands. It features 24x 1G copper ports and 4x 1G SFP uplinks, delivering 128 Gbps switching capacity for applications like data center edge routing, server farms, and cloud gateways. Pre-loaded with Cisco DNA Essentials licensing, it provides basic automation and security for streamlined operations.
Key Technical Specifications
- Port Configuration: 24x 10/100/1000BASE-T ports and 4x 1G SFP uplinks.
- Performance: 128 Gbps switching capacity and 95 Mpps throughput for low-latency traffic.
- Stacking: StackWise-320 support for resilient stacking of up to 8 switches as a single unit.
- Security: MACsec encryption, Cisco TrustSec, and port security for network hardening.
- Licensing: DNA Essentials for automated VLANs, QoS, and firmware management.
C9200L-24T-4G-1A vs. C9200L-24P-4G-A++ (PoE Model)
| Feature | C9200L-24T-4G-1A | C9200L-24P-4G-A++ |
|---|---|---|
| PoE Support | None | 740W PoE+ |
| Power Consumption | 30% lower | Higher due to PoE+ |
| Use Case | Server clusters, data cores | IoT/AP-heavy access layers |
| Cost Efficiency | Lower upfront cost | Higher due to PoE hardware |
Why Deploy the C9200L-24T-4G-1A?
- Cost Savings: Eliminates PoE-related costs for environments like data centers or storage networks.
- High-Density Uplinks: 4x 1G SFP ports enable flexible connectivity to core switches or firewalls.
- Simplified Operations: DNA Essentials automates configuration backups and compliance checks, reducing manual oversight.

- Media Rendering Farms: Handle 4K/8K video workflows with lossless traffic prioritization.
Addressing Critical User Questions
Q: Can this switch support multi-gigabit devices via SFP modules?
Yes. Using 1G/10G SFP+ transceivers, the uplinks can connect to 10G-capable devices for future upgrades.
Q: Is StackWise-320 compatible with older Catalyst 3850 stacks?
No. It requires Catalyst 9200/9300/9400 Series switches running IOS XE 16.12+.
Q: Does DNA Essentials include encrypted traffic analysis?
Yes. Secure Network Analytics monitors SSL/TLS 1.3 traffic for anomalies without decryption.
Final Insight
The C9200L-24T-4G-1A is a no-nonsense workhorse for enterprises where PoE is irrelevant. While it lacks the flash of PoE models, its lean design and cost efficiency make it indispensable for data-centric workloads. In an era of bloated feature sets, this switch proves that simplicity and performance still reign supreme for core infrastructure. Overlooking it for PoE-capable hardware in non-PoE environments is like buying a sports car to haul lumber—unnecessary and wasteful.
