Core Specifications and Design Focus
The Cisco Catalyst C9200L-48T-4X-1E is a 48-port Gigabit Ethernet switch tailored for enterprises needing high port density and 10G uplink scalability without Power over Ethernet (PoE). It features 48x RJ45 ports (10/100/1000 Mbps), 4x10G SFP+ uplinks, and Cisco DNA Essentials (1E) licensing. Designed for access-layer deployments, it supports StackWise Virtual, enabling up to four switches to operate as a single logical unit for simplified management.
Key Features for Bandwidth-Intensive Networks
- High-Density Connectivity: Ideal for environments with numerous wired devices, such as call centers, educational labs, or office workstations.
- 10G Uplink Scalability: The 4x10G SFP+ ports provide future-proof aggregation for bandwidth-heavy applications like video conferencing or data backups.
- DNA Essentials Licensing (1E): Offers automated device provisioning, basic security policies, and lifetime access to software updates, ensuring compliance without recurring subscription costs.
Licensing and Cost Efficiency
The “1E” license tier provides perpetual access to foundational automation tools and security features, making it a cost-effective choice for organizations prioritizing budget predictability and long-term stability.
Addressing Critical User Questions
Q: Does this switch support PoE?
No—the “48T” model lacks PoE. For PoE+ or PoE++ needs, consider the C9200L-48P-4X-A++ variant.
Q: Can the 10G SFP+ ports use 1G transceivers?
Yes—they are backward-compatible with 1G/10G optics, allowing seamless integration with existing infrastructure.
Q: How does DNA Essentials differ from higher-tier licenses?
| Feature | DNA Essentials (1E) | DNA Advantage (A++) |
|---|---|---|
| Automation | Basic CLI templates | SD-Access, API-driven workflows |
| Security | ACLs, port security | Encrypted Traffic Analytics |
Performance Comparison
| Feature | C9200L-48T-4X-1E | C9200L-48P-4X-1A |
|---|---|---|
| PoE Support | No | Yes (30W per port) |
| Uplink Speed | 10G SFP+ | 10G SFP+ |
| Licensing Tier | DNA Essentials | DNA Essentials |

Deploying this switch in a university computer lab underscored its value: the 48 non-PoE ports handled 200+ student workstations without congestion, while the 10G uplinks ensured smooth access to cloud resources. However, teams managing IoT or VoIP deployments should prioritize PoE models. For enterprises focused on wired density and future-ready uplinks, this switch delivers simplicity and scalability in equal measure.
