NETGEAR GS752TXUP-300NAS 48-Port PoE++ Smart Switch with 10G SFP+
Overview
The GS752TXUP-300NAS is a 48-port managed Ethernet switch designed to power and interconnect surveillance cameras, access control systems, and networked security appliances across distributed deployments. With PoE++ (802.3bt) on all 48 gigabit ports, it delivers up to 90W per port—critical for powering high-draw devices like PTZ cameras, multi-sensor arrays, and industrial-grade outdoor equipment without requiring separate power injectors. The dual 10G SFP+ uplinks enable non-blocking backhaul to NVRs, video management servers, or core network infrastructure, eliminating bottlenecks when aggregating feeds from dozens of cameras.
Compatibility
The GS752TXUP-300NAS integrates with any ONVIF-compliant IP camera, network-attached access control panel, or VMS appliance that accepts standard Ethernet PoE injection. It is backward-compatible with PoE+ (802.3at) and legacy PoE (802.3af) devices, allowing mixed deployments of older and newer equipment on the same switch without reconfiguration. The 10G SFP+ uplinks accept standard SFP+ transceiver modules, including direct-attach copper (DAC) cables for short runs (up to 7 meters) or fiber optics for longer distances, making it suitable for both compact server rooms and geographically dispersed camera distribution networks.
Installation Notes
The switch requires a 100–240V AC power input and is typically installed in a 19-inch equipment rack using the included mounting brackets. Plan for adequate power supply capacity: with all 48 ports delivering maximum PoE++, total system draw can exceed 4.8 kW under worst-case load. Segment camera VLANs using the built-in managed switching capabilities to isolate surveillance traffic from corporate networks and improve security posture. Gigabit runs from cameras to the switch should not exceed 100 meters per IEEE 802.3 standard; for longer runs, consider fiber-to-Ethernet converters or additional access switches positioned closer to remote cameras.
