Netgear AV Line M4250-40G8XF-PoE++ (GSM4248UX) 40x1G PoE++ 2,880W and 8xSFP+ Managed Switch - GSM4248UX-100NAS

Product Overview

The Netgear AV Line M4250-40G8XF-PoE++ (GSM4248UX-100NAS) is a high-density PoE++ AV switch designed to power and connect demanding AV endpoints across many rooms from a single rack-mount chassis. It pairs 40 Gigabit Ultra90 PoE++ copper ports with eight 1G/10G SFP+ fiber uplinks, delivering up to 2,880W of PoE budget for dense high-wattage deployments. As the highest-power switch in the M4250 AV Line, it is built for AV-over-IP installations driving PTZ cameras, displays, and lighting at 60-90W per port. The 1U platform consolidates audio, video, and control onto one managed 240 Gbps non-blocking fabric.

Product Description

The M4250-40G8XF-PoE++ acts as a high-power access switch, powering endpoints throughout boardrooms, conference spaces, and venues while uplinking to the AV core over 10G fiber. Each of the 40 copper ports supports 802.3af, at, and bt PoE up to 90W with Ultra90, and three internal power supplies scale the PoE budget to 720W with one PSU, 1,650W with two, or 2,880W with all three installed. The included AV web GUI provides certified profiles for Dante, Q-SYS, AES67, AVB, NDI, Crestron NVX, and AMX SVSI, while NETGEAR IGMP Plus simplifies Layer-2 multicast for AV-over-IP without PIM. A full Layer 3 engine adds static, RIP, and PIM routing, a DHCP server, and PTPv2 timing for synchronized media. Triple-PSU RPS/EPS redundancy supports business continuity, and the switch ships pre-configured for standard audio and video signals. Single-pane management is available via NETGEAR NMS300, and the switch is backed by NETGEAR's ProSAFE limited lifetime hardware warranty. The eight SFP+ ports provide flexible 1G or 10G fiber uplinks to aggregation or core switches.

Key Features

• 40x 1G Ultra90 PoE++ Ports — Forty Gigabit RJ45 ports deliver Ultra90 PoE++ to power high-wattage AV endpoints directly over the network cable.
• 2,880W Maximum PoE Budget — Three internal power supplies scale the PoE budget to 720W, 1,650W, or 2,880W to match endpoint density and wattage.
• 802.3af/at/bt Support — Per-port PoE up to 90W powers PTZ cameras, displays, and lighting without separate power injectors.
• 8x 1G/10G SFP+ Uplinks — Eight SFP+ fiber ports provide flexible 1G or 10G uplinks to the AV aggregation or core layer.
• 240 Gbps Non-Blocking Fabric — A non-blocking switching fabric across all 48 ports sustains wire-speed AV traffic.
• AV GUI with Certified Profiles — The dedicated AV web GUI provides profiles for Dante, Q-SYS, AES67, AVB, NDI, NVX, and SVSI for fast AV-over-IP deployment.
• NETGEAR IGMP Plus Multicast — Layer-2 multicast control streamlines AV-over-IP multicast management without requiring PIM.
• Full Layer 3 Routing and PTPv2 — Static, RIP, and PIM routing, a DHCP server, and PTPv2 timing support converged L2/L3 AV networks.
• Triple-PSU Redundancy — RPS/EPS triple power-supply redundancy supports business continuity for mission-critical installations.
• ProSAFE Limited Lifetime Warranty — Backed by NETGEAR's ProSAFE limited lifetime hardware warranty.

Frequently Asked Questions

How much PoE power does this switch provide?
With all three internal power supplies installed, it delivers up to 2,880W of PoE budget, supporting up to 90W per port via Ultra90 802.3bt.

Can it power PTZ cameras, displays, and lighting?
Yes. The high per-port wattage and large PoE budget are designed for dense, high-wattage AV endpoints such as PTZ cameras, displays, and lighting.

How do the SFP+ uplinks integrate with an AV core?
The eight 1G/10G SFP+ ports uplink to your AV aggregation or core switch over fiber, letting this switch serve as a high-power access layer.

Does it support networked audio and video protocols?
Yes. The AV GUI includes certified profiles for Dante, Q-SYS, AES67, AVB, NDI, Crestron NVX, and AMX SVSI. AVB requires a license.

What warranty and management options are included?
It carries NETGEAR's ProSAFE limited lifetime hardware warranty and supports single-pane management via NETGEAR NMS300. Contact our team for design support.
