NETGEAR GSM4248UX — M4250-40G8XF-PoE++ Managed Switch 40x1G Ultra90 PoE++ 802.3bt 2,880W and 8xSFP+ AV Line (GSM4248UX)

NETGEAR GSM4248UX Fully Managed Gigabit PoE++ Switch for SMB and AV Networks

The NETGEAR GSM4248UX (M4250‑40G8XF‑PoE++) is a fully managed Layer 3 switch engineered for small to mid‑size business and AV‑over‑IP environments that require dense Gigabit connectivity, ultra‑high PoE power, and clean rack deployments. As part of the NETGEAR AV Line M4250 Series, it combines enterprise networking features with simplified, AV‑friendly configuration.

High‑Density Gigabit PoE++ Access

The GSM4248UX provides 40 × Gigabit Ethernet PoE++ ports, each capable of delivering up to 90W per port. This makes it ideal for powering access points, encoders and decoders, cameras, control systems, and other PoE‑dependent devices commonly found in modern SMB and AV installations.

10G SFP+ Uplinks for Aggregation and Core Connectivity

To handle uplink and aggregation traffic, the switch includes 8 × 10G SFP+ fiber ports. These uplinks ensure sufficient bandwidth for AV streams, wireless traffic, and data‑intensive workloads while supporting clean inter‑switch connectivity and scalable network design.

Massive PoE Capacity for Power‑Dense Environments

With support for modular, redundant power supplies, the GSM4248UX can deliver a total PoE budget of up to 2,880W. This makes it well‑suited for environments with a high number of powered devices, reducing the need for external power injectors and simplifying installation.

Optimized for AV‑over‑IP and Business Applications

Built‑in enhanced multicast support enables efficient delivery of audio and video streams without network flooding. The design features rear‑facing ports and quiet or fanless operation, making it ideal for AV racks, conference rooms, and environments where aesthetics and noise control matter.

Simplified Management for IT and AV Teams

The GSM4248UX supports both a dedicated AV‑focused web interface and a standard IT management interface, along with CLI and centralized management options. This dual‑mode approach allows SMB IT teams and AV professionals to deploy and manage the switch efficiently using familiar workflows.
