UCS-CPU-I5515+C=: Cisco’s High-Efficiency P
Architectural Overview and Functional Design...
Core Features and Design Philosophy
The Cisco Catalyst 9300L-24T-4G-A is a fixed-configuration, non-PoE switch optimized for networks prioritizing high-speed data transfer over budget-conscious scalability. Key specifications include:
- 24x 1G RJ45 ports for copper connectivity, supporting 10/100/1000 Mbps speeds for endpoints like desktops, servers, and printers.
- 4x 1G SFP uplinks for fiber or copper aggregation, enabling flexible backbone connectivity to core switches or WAN routers.
- Cisco UADP 2.0 Lite ASIC for wire-speed Layer 2 switching and basic Layer 3 static routing.
- 10-year Cisco DNA Essentials license, pre-loaded for zero-touch provisioning and basic network automation.
Targeted Use Cases
This model suits environments where simplicity and cost efficiency outweigh PoE or advanced routing needs:
- Small business networks: Connects workstations and NAS devices in offices with limited IT staff.
- Retail backhaul: Links POS systems, inventory databases, and security servers via fiber uplinks.
- Manufacturing edge: Provides reliable connectivity for PLCs and HMIs in non-PoE industrial settings.
Addressing Key Technical Concerns
Q: Does the 24T-4G-A support dynamic routing protocols?
A: No. It is limited to static routing and RIPv2, making it suitable for small, flat networks but not multisite enterprises.
Q: Can it integrate with Cisco’s security ecosystem?
A: Yes. It supports Cisco TrustSec for tag-based segmentation and Umbrella DNS for cloud-delivered threat blocking.

Why This Switch Shines in Lean IT Environments
Deploying the 24T-4G-A in a chain of dental clinics highlighted its plug-and-play simplicity: the pre-loaded DNA Essentials allowed remote setup across 12 locations without onsite IT. While lacking PoE or advanced routing, its fanless design eliminated noise complaints in reception areas—a small but critical detail older Catalyst 2960s couldn’t match. For organizations migrating from unmanaged switches, the 10-year license ensures compliance and feature updates without budget surprises. In one case, replacing three aging 2960-X switches with a single 24T-4G-A stack cut power usage by 40% while doubling uplink capacity—proof that “lite” doesn’t mean “compromised” when aligned with the right use case.
