Cisco Catalyst CBS350-24FP-4G 24-Port PoE+ Managed Switch

Enterprise-grade 24-port Gigabit PoE+ managed switch sized for commercial surveillance backbones requiring 24-camera capacity with full layer-3 routing.

Deployment context

Mid-sized commercial installations: office buildings, schools, healthcare facilities, government buildings supporting 16-24 cameras plus access control IP devices on a single managed switch.

Port count & PoE budget

24× Gigabit PoE+ ports (802.3at, 30W per port). Total PoE budget 370W — fully populates 12 PTZ/IR cameras at full PoE+, or 24 fixed cameras with margin. 4× SFP uplinks for fiber or 10G aggregation.

VLAN & management capabilities

Full VLAN 802.1Q segmentation (4094 VLANs), 802.1X port authentication, SNMP v1/v2/v3, RADIUS/TACACS+, dynamic ARP inspection. Cisco Business Dashboard or local web UI. Standard for spec-compliant surveillance network segregation.

Surveillance infrastructure implications

Recommended deployment: dedicated surveillance VLAN with QoS prioritizing camera traffic. Multicast (IGMP snooping) for NVR-to-VMS streams. Built-in storm control for camera-flood scenarios. Pairs cleanly with Hanwha XRN-1620SB or XRN-3210B2 NVRs over fiber uplink.

Thermal / rack / power considerations

1U rack-mount, fan-cooled. Operating range 0-50°C. Standard 2-post or 4-post rack. 90W idle / 470W max PoE load. UPS sizing: ~600W headroom needed for redundant deployment.
