Netgear CSM4316-100NES

Product Overview

The NETGEAR M4350-16C (CSM4316) is a 16-port 100G managed AV switch built for the core and aggregation layer of large AV-over-IP and IT networks. With sixteen QSFP28 ports and 3.2 Tbps of switching capacity, this fully managed Layer 3 AV switch aggregates high-bandwidth uplinks from M4250 and M4350 edge switches in broadcast, stadium, and large-venue installations. It ships with preconfigured profiles for major audio, video, and lighting protocols and supports SMPTE ST 2110 timing, reducing configuration time during commercial AV deployment. Rack-mount in 1U, it is engineered as a 100G aggregation switch for AV and IT cores.

Product Description

The M4350-16C sits at the top of the NETGEAR M4350 series and is purpose-built for the network core where uncompressed AV-over-IP traffic converges. Its sixteen 100G QSFP28 ports provide the bandwidth headroom needed to backhaul SMPTE ST 2110, NDI, and SDVoE streams from dozens of edge switches without contention. As a fully managed Layer 3 AV switch, it supports static and dynamic routing, IGMP querier/snooping, and NETGEAR IGMP Plus for reliable multicast distribution across subnets — a core requirement in AV-over-IP core switch designs.

The NETGEAR AV user interface and Engage Controller expose preconfigured protocol profiles, so integrators can commission a broadcast studio or auditorium network without building multicast policy from scratch. Auto-trunk and auto-LAG automatically form links to other M4250 and M4350 switches, simplifying multi-switch fabrics in stadiums and production facilities. The switch implements ST 2110 profiles with Boundary Clock and Grandmaster Clock modes plus PTP profiles for SMPTE 2059-2, AES67, and AES-R16-2016, giving AV system designers precise timing for synchronized video and audio. With Non-Stop Forwarding (NSF) and stacking over 100G, it delivers the availability expected of a commercial AV aggregation switch in 24/7 environments. A single fixed 420W power supply keeps the 1U chassis compact for dense racks. For edge connectivity that feeds this core, see our full NETGEAR switch collection at Creation Networks.

Frequently Asked Questions

What edge switches does the M4350-16C aggregate?
It is designed to backhaul uplinks from NETGEAR M4250 and M4350 edge switches, forming a 100G AV-over-IP core via auto-trunk and auto-LAG.

Does it support SMPTE ST 2110 timing?
Yes. It supports ST 2110 profiles with Boundary Clock and Grandmaster Clock modes, plus PTP profiles for SMPTE 2059-2, AES67, and AES-R16-2016.

Is it suitable for a broadcast or production core?
Yes. With 3.2 Tbps capacity, line-rate forwarding, and Non-Stop Forwarding, it targets broadcast studios, auditoriums, and large-venue production networks.

How is it mounted and powered?
The switch is a 1U rack-mount chassis with a single fixed 420W power supply (C14 inlet) and an expansion slot for added power.

Can it route between AV and IT VLANs?
Yes. As a fully managed Layer 3 switch it provides IPv4/IPv6 routing, VLANs, and ACLs to segment AV-over-IP traffic from corporate networks.

What management tools are included?
The NETGEAR AV user interface and Engage Controller provide preconfigured protocol profiles and centralized management for commercial AV deployments.

What warranty and support apply?
NETGEAR ProAV switches are covered by NETGEAR's commercial warranty and support program. Contact Creation Networks for current warranty terms and integration support.
