The Cisco CBS350-48XT-4X-NA is a 48-port Layer 2+ managed switch engineered for North American enterprises and campuses requiring high-density Power over Ethernet (PoE) and multi-gigabit uplinks. Combining a robust PoE budget with 10G scalability, it addresses the needs of modern IoT-heavy environments. Below, we analyze its technical capabilities and answer critical deployment questions.
Key Features for Scalable NA Deployments
- 48 x PoE+ Ports (740W Total): Delivers 30W per port (60W with Cisco UPOE*), supporting Wi-Fi 6E APs, PTZ cameras, and digital signage.
- 4 x 10G SFP+ Uplinks: Enables high-speed backbone connectivity for bandwidth-intensive tasks like 4K video streaming or large-scale data backups.
- Layer 2+ Lite Features: Includes static routing (IPv4/IPv6) for basic inter-VLAN communication and QoS policies for traffic prioritization.
- NA Compliance: Operates at 120V AC, certified for FCC Part 15/UL 60950, and optimized for 60Hz power grids.
Technical Specifications
| Attribute | Detail |
|---|---|
| Switching Capacity | 136 Gbps |
| PoE Budget | 740W (60W UPOE on 12 ports*) |
| Noise Level | 38 dB (under full load) |
| Dimensions | 440 x 445 x 44 mm |
*UPOE requires compatible Cisco endpoints.
Addressing Core User Concerns
Q: Can this switch power 48 devices at full PoE+ capacity?
No. The 740W total budget allows ~15.4W per port if all 48 ports are active. For high-power devices (e.g., 30W APs), allocate UPOE ports strategically.
Q: Why prioritize 10G uplinks over 2.5G/5G alternatives?
10G uplinks future-proof networks for emerging technologies like 8K surveillance systems or AI-driven IoT hubs, which demand higher throughput.
Q: How does it enhance network segmentation?
VLAN stacking (Q-in-Q) and private VLANs isolate traffic for multi-tenant environments (e.g., shopping malls, co-working spaces).
Practical Deployment Scenarios
- Best For:
- University campuses with high-density device deployments (e.g., classrooms, labs).
- Warehouses using automated inventory systems or PoE-powered robotics.
- Avoid If:
- You require dynamic routing protocols (e.g., OSPF, BGP) or redundant power supplies.
Final Insight
Having reviewed Cisco’s technical briefs and deployment guides, the CBS350-48XT-4X-NA stands out for high-density PoE environments needing cost-effective Layer 2+ scalability. Its 740W budget accommodates modern IoT ecosystems, though power allocation requires careful planning. For pricing and availability, explore the CBS350-48XT-4X-NA here. While not a fit for hyperscale data centers, it’s a versatile solution for IT teams balancing performance, security, and budget in demanding NA markets.
