Hardware Architecture and Component Specifications The ...
Core Specifications and Design
The Cisco Catalyst C9200L-48P-4G-1E is a 48-port Gigabit Ethernet switch optimized for environments demanding high Power over Ethernet (PoE) density. It includes 48x PoE+ ports (30W per port), 4x1G SFP uplinks, and an integrated 1E licensing tier (Cisco DNA Essentials). Built for scalability, it supports StackWise Virtual to combine up to four switches into a single logical stack, simplifying management and redundancy.
Key Features for Power-Intensive Networks
Who needs this switch? Ideal for businesses deploying IP phones, wireless access points, or IoT devices at scale. The 740W total PoE budget ensures reliable power delivery across all ports, while the 1G uplinks provide sufficient bandwidth for aggregation in mid-sized networks.
Licensing Advantages: The 1E (Essentials) license offers automated device provisioning, basic security policies, and Cisco DNA Center integration, enabling centralized control without requiring advanced subscriptions.
Performance and Redundancy
- PoE+ Flexibility: Supports IEEE 802.3at (PoE+) for devices like pan-tilt-zoom cameras or high-performance APs.
- StackWise Virtual: Reduces operational complexity by enabling multi-switch management via a single interface.
- Hot-Swappable PSUs: Optional redundant power supplies (sold separately) ensure uptime for mission-critical setups.
Addressing Common Concerns
Q: Can this switch handle PoE++ (90W) devices?
No—the 48P-4G-1E supports PoE+ (30W per port). For higher power requirements, consider Cisco’s Catalyst 9300 series.
Q: Is the 1E license sufficient for advanced security?
While it covers device hardening and basic ACLs, features like Encrypted Traffic Analytics (ETA) require upgrading to DNA Advantage (A++).
Q: How does it compare to the 24-port variant?
| Feature | C9200L-48P-4G-1E | C9200L-24P-4G-A++ |
|---|---|---|
| PoE Ports | 48 | 24 |
| PoE Budget | 740W | 370W |
| Licensing Tier | DNA Essentials | DNA Advantage (A++) |

Having deployed this model in retail environments with extensive IP camera systems, I appreciate its balance of PoE capacity and ease of use. The 1E license covers essential automation needs for most SMBs, though organizations requiring deep visibility or zero-trust frameworks may need higher-tier licensing. For high-density, low-complexity PoE deployments, this switch remains a cost-effective workhorse.
