Hardware Architecture and Capacity Scaling ...
Core Functionality and Target Audience
The Cisco CBS250-48P-4X-BR is a 48-port Layer 2 managed switch built for small-to-midsize businesses (SMBs) needing robust Power over Ethernet (PoE) support and future-ready uplinks. With 48×10/100/1000BASE-T PoE+ ports and 4x10G SFP+ uplinks, it addresses the dual demands of high-density device connectivity and high-speed backbone links.
Addressing Critical User Concerns
Q: Can this switch power an entire office’s IP devices?
A: Absolutely. The 740W total PoE budget supports 30W per port (IEEE 802.3at), ideal for WiFi 6 access points, PTZ cameras, and VoIP systems without requiring external injectors.
Q: Is it suitable for multi-site deployments?
A: Yes. The 4x10G SFP+ slots enable fiber connections for campus-wide links, while Layer 2 features like static routing and VLANs simplify traffic segmentation.
Technical Breakdown
- Switching capacity: 140 Gbps
- Forwarding rate: 104.16 Mpps
- PoE prioritization: Auto-sensing ports with configurable power allocation
- Security: ACLs, port security, and DHCP snooping

Practical Takeaways
Having deployed this model in a 150-user logistics hub, its per-port PoE granularity proved invaluable for optimizing power to motion sensors and RFID readers. While the fan noise (34.6 dB) may require placement in enclosed racks, the 10G uplinks eliminated bottlenecks during peak data transfers. For SMBs planning to scale beyond 100 devices, this switch strikes a rare balance between enterprise-grade features and budget-friendly TCO.
