Netgear AV Line M4250 28-Port PoE+ Managed Switch with SFP+ 480W

The Netgear AV Line M4250 28-Port PoE+ Managed Switch with SFP+ 480W is a high-density rack-mountable managed switch built for large-scale 1G AV over IP deployments. Engineered with input from industry professionals, the Netgear AV Line M4250 28-Port PoE+ Managed Switch with SFP+ 480W ships pre-configured for out-of-the-box use, combining a 480W PoE budget, four 10G SFP+ uplinks, and a dedicated AV web interface in a shallow 1U chassis with all ports rear-facing.

24 PoE+ Ports, Four 10G SFP+ Uplinks, and 480W Budget

All 24 rear-facing RJ45 ports deliver Gigabit speeds with up to 30W of PoE+ power each, backed by a 480W total budget capable of running cameras, encoders, access points, and AV endpoints across an entire room or floor. Four 10G SFP+ uplink slots provide high-speed fiber connectivity to core switches or distribution layers, and two additional Gigabit RJ45 LAN ports offer further integration flexibility. Auto-Trunk and Auto-LAG functionality automatically links M4250 and M4300 series switches, simplifying multi-switch deployments.

132 Gb/s Switching with Quad-Core CPU

A quad-core 1.8 GHz ARM Cortex-A57 CPU drives a 132 Gb/s switching bandwidth and 98.21 Mpps forwarding rate, delivering significantly more headroom than the single-core models in the M4250 series. With a 16 Mb packet buffer, 16K MAC address table, and jumbo frame support up to 12,000 bytes, the switch handles dense multi-stream AV environments without introducing latency or congestion. Layer 2 and Layer 3 switching supports static routing, RIP, PIM, and PTPv2 alongside standard protocols including DHCP Server, IGMP Snooping, IPv4, IPv6, Link Aggregation, and Port Mirroring.

Pre-Configured for AV over IP

Built-in Netgear IGMP Plus™ enables instant multicast functionality for most AV over IP installations without additional configuration. The dedicated AV web-based interface uses color-coded, port-based profiles to make assigning configurations straightforward for AV professionals. Video profiles for NVX, SVSI, Q-SYS, and Dante can be assigned to ports as needed, and audio profiles for Dante and AES67 are available out of the box. Audio Video Bridging (AVB) is supported via firmware update for deployments requiring very low latency.

Flexible Rack Mounting and Management

The 1U chassis measures 7.9" deep with all ports rear-facing for clean cable management in AV racks. Standard and recessed mounting brackets are included, and outside-rack mounting is supported via bottom M5 and front M10 threaded holes. Management is available via the built-in AV web GUI, IT web GUI, console, Telnet, and SSH. Two USB-C management ports and one USB-A port provide direct console access. Security features include DHCP Snooping, DoS Attack Prevention, RADIUS Authentication, and Storm Control.
