Managed PoE Switch Netgear M4250 12-Port (Model GSM4212PX) – 12-Port PoE, AV Line

The Netgear M4250 12-Port AV Line PoE Switch (GSM4212PX) is a managed network switch designed for audio/video distribution and network edge deployments. It offers twelve RJ45 ports with Power over Ethernet (PoE) capability and a set of management functions for VLANs, Quality of Service (QoS) and traffic control. The unit is part of Netgear's M4250 AV Line family, providing an interface between AV devices, access points, IP cameras and core network infrastructure while enabling centralized configuration and monitoring.

Advantages

The switch supports powered devices on all data ports, simplifying installation of AV endpoints and network devices without separate power supplies. Management features such as VLAN segmentation, QoS prioritization and traffic shaping allow reliable delivery of audio and video streams and better control of multicast traffic. A compact 12‑port form factor is suitable for edge racks and installation locations with limited space. The device integrates with standard Ethernet networks and common AV deployment practices, enabling consistent performance and centralized network policy enforcement.

Suitable for

• Audio/video distribution and signal endpoints in conference rooms or lecture halls
• Edge networking for small enterprises, retail sites or campus buildings
• Powering and connecting IP cameras, Wi‑Fi access points and AV endpoints
• Environments requiring VLANs and QoS to prioritise media traffic

Key specifications

• 12 RJ45 Ethernet ports with Power over Ethernet capability
• Managed switch with VLAN, QoS and traffic control features
• AV‑oriented feature set for multicast and media traffic handling
• Compact 12‑port form factor suitable for edge installations
• Web and command‑line management interfaces for configuration and monitoring

How to use

Mount the switch in an appropriate rack or place on a stable surface and connect Ethernet cables from AV sources, endpoints and uplink ports. Configure management settings via the web interface or command line to define VLANs, set QoS priorities and enable PoE on required ports. Use multicast and IGMP settings where applicable to optimize distribution of audio/video streams and monitor device status and traffic through the management tools.

Usage recommendations

Enable VLAN segmentation for separating AV traffic from general data, apply QoS policies to prioritise real‑time media streams, and verify PoE budgets before connecting multiple powered devices to ensure stable power delivery to all endpoints.
