Netgear CSM4316-100NES — 16-port 100G fully managed AV switch
The NETGEAR M4350-16C (CSM4316) is a fully managed AV Line switch built for the core and distribution layer of demanding AV-over-IP and broadcast networks. With sixteen 100G QSFP28 ports in a compact 1U chassis, it aggregates high-bandwidth uncompressed video traffic between encoders, decoders and edge switches. Pre-defined AV profiles, NETGEAR AV OS and the Engage Controller let integrators configure ports for specific AV applications in just a few clicks, while NETGEAR IGMP Plus delivers reliable multicast out of the box. Targeted at AV integrators, broadcast facilities and large venues, it combines a full Layer 3 feature set, Virtual Chassis stacking and SMPTE ST 2110 clock support to keep large media deployments fast, resilient and easy to manage.
Sixteen 100G QSFP28 Ports for the Core
The CSM4316 packs sixteen 100 Gigabit QSFP28 ports into a single 1U chassis, giving the network a high-density aggregation point for uncompressed AV-over-IP traffic. At the core or distribution layer, dozens of edge switches feeding 1G/10G/25G endpoints can be uplinked here without creating bottlenecks. For the operator running a large venue, stadium or broadcast facility, this headroom means video streams arrive without congestion-related stutter or dropped frames even when many sources and displays are active at once, and it leaves room to scale the installation later without re-architecting the backbone.
Pre-Defined AV Profiles and Simple GUI
NETGEAR AV OS and the Engage Controller provide a streamlined interface where certified AV profiles are assigned to individual ports in a few clicks, instead of hand-configuring VLANs, QoS and multicast settings. This removes most of the deep networking knowledge usually needed to commission an AV-over-IP system. In practice the install goes faster and with fewer mistakes, so the end customer gets a network that behaves predictably from day one and a multi-color per-port LED that mirrors the assigned profile, making on-site troubleshooting and patching far quicker.
NETGEAR IGMP Plus Multicast Out of the Box
Reliable multicast is the foundation of AV-over-IP, and misconfigured IGMP snooping is a common cause of failed deployments. NETGEAR IGMP Plus enables correct multicast handling automatically for most AV applications without manual tuning. For the end user this means video and audio streams replicate cleanly to the intended displays only, avoiding the flooding that can cripple a network. The result is dependable, flicker-free delivery from first power-on and noticeably fewer support calls about missing or frozen sources.
SMPTE ST 2110 Clocking for Broadcast
The switch supports SMPTE ST 2110 Grandmaster and Boundary Clock functions for AES67 and ST 2059-2 applications. This matters in professional broadcast and live-production environments where audio and video essence streams must stay precisely time-aligned across the whole facility. Building PTP timing into the switch itself removes the need for separate clocking hardware and keeps lip-sync and inter-stream timing tight. For the end user that translates into broadcast-grade reliability and clean, synchronized output suitable for live and studio production.
Virtual Chassis Stacking with Hitless Failover
Virtual Chassis stacking lets multiple units be managed as one logical switch while providing non-stop forwarding and hitless failover. If a stack member or link fails, traffic keeps flowing rather than dropping the AV streams that depend on it. For the end user operating an always-on environment such as a broadcast playout chain or a 24/7 control room, this resilience protects against single points of failure, so a hardware fault does not turn into black screens or dead audio during a live event.
Layer 3 Routing for Scalable Networks
A full Layer 3 feature set with static, policy-based and dynamic routing means the CSM4316 can route between subnets itself rather than relying on a separate core router. Large AV deployments are often segmented into many VLANs for different rooms, signal types or tenants, and on-switch routing keeps that traffic moving efficiently at line rate. For the end user this keeps latency low and the design clean, allowing the network to grow across floors or buildings without bolting on extra routing hardware.
Quiet Mode and Redundant Power
The chassis runs a 420W internal supply plus a slot for a modular redundant PSU (1+1) using APS600Wv3, APS1200Wv2 or APS2000Wv2 units, and offers a Quiet Mode rated at 30.4dB at 25°C. Redundant power keeps the switch online if one supply fails, important when it sits at the heart of an AV network. The low-noise operation matters in environments where the switch shares space with people, such as a studio, boardroom or AV rack near a live area, so timing-critical media keeps flowing without adding distracting fan noise to the room.
