NETGEAR M4250-40G8XF-PoE++ Managed L2/L3 Gigabit Ethernet (10/100/1000) Power over Ethernet (PoE) 2U Black

The NETGEAR M4250-40G8XF-PoE++ (Managed Switch NETGEAR M4250-40G8XF-PoE++) is a rack-mountable L2/L3 managed switch designed for AV over IP deployments and high-performance networks. It provides 40 Gigabit Ethernet ports with Power over Ethernet support (IEEE 802.3af/at/bt), a 240 Gbit/s switching capacity and a 16,000-entry MAC address table. The compact 2U chassis includes industry-standard threaded mounting holes for behind-display or truss mounting and offers quiet, adjustable cooling for noise-sensitive environments.

Advantages

Pre-configured NETGEAR IGMP Plus™ enables immediate multicast support for most AV over IP installations, reducing engineering time required for initial setup. The dedicated AV web-based GUI uses color-coded, port-based profiles to simplify assignment of audio and video protocols. Built-in video and audio profiles (including NVX, SVSI, Q-SYS, Dante, AES67 and AVB — AVB requires a separate license) and automatic configuration features such as auto-trunk and auto-lag help streamline deployment in star topologies. The switch supports multiple PoE standards and provides flexible mounting options and an overall quieter operation than many comparable switches.

Suitable for

• AV over IP installations (concert halls, corporate AV, education facilities)
• Environments requiring multicast video and audio distribution
• Installations needing Power over Ethernet for endpoints (IP cameras, access points, Dante devices)
• Racked server rooms or concealed mounting behind displays and on trusses

How to use

Install the switch in a 2U rack or mount it using the chassis threaded holes behind a display or on a truss. Connect network devices to the Gigabit Ethernet ports and enable PoE where required for powered endpoints. Use the AV-focused web GUI to assign factory or custom port profiles for Dante, AES67, AVB (license required for AVB), NVX, SVSI or Q-SYS video, or rely on the pre-configured NETGEAR IGMP Plus™ settings for immediate multicast functionality. For multi-switch star topologies, enable auto-trunk and auto-lag to allow the M4250 family to configure linked switches automatically.

Recommendations

For noise-sensitive locations, enable Quiet mode or turn off adjustable fans when environmental conditions permit. Verify AVB licensing before deploying AVB profiles and confirm PoE budget planning to ensure sufficient power for all connected devices.
