Comnet CWX28F4T24MPB Managed PoE Switch
Overview
The CWX28F4T24MPB is a 28-port managed L2+ switch purpose-built for commercial surveillance deployments and industrial networking. It combines 24 Gigabit copper ports (split 8x PoE+90W and 16x PoE+30W) with 4 SFP+ fiber ports capable of 10G uplink speeds. The 540W PoE budget handles mid-to-large camera clusters without requiring external injectors. NDAA and TAA compliance make it suitable for federal, state, and municipal projects where supply-chain verification is mandatory.
Compatibility
This switch pairs with any standard 802.3at or 802.3bt PoE-capable device: IP cameras (Axis, Hikvision, Uniview, Hanwha, Dahua), NVRs with PoE uplink requirements, access-control readers, intercoms, and VMS servers. The 8 ports rated for 90W each support high-draw cameras (panoramic, PTZ, or multi-sensor domes). The 16 standard-PoE ports handle 30W fixed cameras and thermal cameras. Fiber uplinks connect to existing data-center switches or link distant surveillance nodes without ground-loop risk — common in large campuses or maritime installations.
Installation Notes
Mount in a 19-inch rack with the internal power supply (no external PSU required). Verify total connected PoE load does not exceed 540W aggregate — the switch will not oversubscribe. Use CAT6 or better cabling to avoid voltage drop on longer runs (above 100m, consider PoE extenders). Configure VLAN tagging to isolate camera traffic from management networks; this switch supports L2+ intelligence for QoS and port mirroring to your VMS or SIEM. TAA/NDAA compliance requires genuine firmware from the manufacturer — do not load unsigned images.
