These features allow businesses to segment their network efficiently, optimizing data flow between different departments or workgroups while maintaining high performance and minimal latency. The switch’s ability to handle multiple routing protocols ensures interoperability with existing network infrastructures and simplifies complex network topologies.

Optimized Traffic Management

With advanced QoS (Quality of Service) features, the CBS350-24NGP-4X prioritizes critical network traffic to ensure smooth performance for voice, video, and data applications. Traffic shaping and congestion management capabilities minimize packet loss and latency, supporting seamless VoIP and video conferencing experiences. Layer 3 multicast routing support further enhances the switch’s ability to efficiently distribute streaming content or broadcast services across multiple network segments.

Inter-VLAN Routing and Subnet Segmentation

The switch supports inter-VLAN routing, enabling the creation of multiple logical networks within the same physical infrastructure. Subnet segmentation improves network security by isolating sensitive data, while efficient routing ensures rapid communication between VLANs without compromising performance. This feature is especially valuable in environments where multiple departments require independent network segments but still need reliable connectivity between them.

16 Gigabit PoE+ Ports for Flexible Device Integration

The CBS350-24NGP-4X comes equipped with 16 10/100/1000 Mbps PoE+ ports, capable of delivering sufficient power for a wide range of devices, including IP phones, wireless access points, and surveillance cameras. With the ability to provide up to 30W per port, these PoE+ ports eliminate the need for separate power supplies, reducing clutter and installation complexity. This integration of data and power over a single cable simplifies deployment and maintenance, particularly in enterprise environments where multiple powered devices are deployed.

10 Gigabit SFP+ Uplinks for Backbone Efficiency

Two 10 Gigabit SFP+ uplink ports and four additional SFP+/RJ-45 combo ports allow the CBS350-24NGP-4X to serve as a high-speed backbone switch, connecting multiple network segments or aggregating traffic from smaller access switches. This high-speed uplink capability supports bandwidth-intensive applications such as data center interconnects, high-definition video streaming, and cloud-based services.
