CBS250-48P-4G-IN: Can Cisco’s 48-Port PoE Switch Handle High-Density Networks Without Breaking a Sweat?

What Is the CBS250-48P-4G-IN Designed For?

The ​​CBS250-48P-4G-IN​​ is a Layer 2 managed switch from Cisco’s Small Business Series, purpose-built for medium-sized networks requiring ​​high-density Power over Ethernet (PoE)​​ support. With ​​48 PoE+ ports​​ and ​​4 Gigabit SFP uplinks​​, it caters to environments demanding simultaneous connectivity for devices like IP cameras, wireless access points, and VoIP systems.

Critical Technical Capabilities

• ​​Port Configuration​​: 48x 10/100/1000 PoE+ ports (30W per port) + 4x 1G SFP uplinks.
• ​​PoE Budget​​: ​​370W total​​, enabling simultaneous power delivery to 24 ports at 30W or 48 ports at lower wattages.
• ​​Layer 2 Features​​: Advanced VLAN, QoS, ACLs, and IGMP snooping for optimized traffic flow.
• ​​Scalability​​: Static routing and stacked VLANs for multi-site coordination.
• ​​Cooling​​: Dual fan design for sustained performance in high-temperature deployments.

Solving Common User Questions

​​Q: Is the PoE budget sufficient for 48 devices?​​
A: While the 370W limit supports powering all 48 ports, realistic deployments require prioritizing high-wattage devices (e.g., pan-tilt-zoom cameras). For mixed loads (15–20W per device), full port utilization is achievable.

​​Q: Can this switch replace an enterprise-grade core switch?​​
A: No. The CBS250-48P-4G-IN excels as an ​​access layer switch​​, handling edge device connectivity. For core routing or heavy inter-VLAN traffic, consider Cisco Catalyst series.

​​Q: Does it support cloud management?​​
A: Yes. The ​​Cisco Business Dashboard​​ provides centralized monitoring, firmware updates, and configuration backups without requiring CLI expertise.

Ideal Use Cases

• ​​Surveillance Systems​​: Power 24+ 4K IP cameras with bandwidth reserved for real-time feeds.
• ​​Campus Wi-Fi 6 Deployments​​: Connect 40+ access points while using SFP uplinks for fiber backhaul.
• ​​Hybrid Offices​​: Integrate deskside VoIP phones, HVAC controls, and lighting systems via PoE.

Final Perspective

After configuring similar switches for warehouse surveillance setups, the ​​CBS250-48P-4G-IN​​ impresses with its ​​no-nonsense PoE density​​ and ​​thermal resilience​​. While lacking Layer 3 routing, its ability to simplify cabling and power management for sprawling device networks makes it a silent workhorse for IT teams aiming to “set and forget” critical infrastructure.
