Netgear M4300-28G-PoE+ (GSM4328PB) - L3 Stackable Managed Switch with 24 PoE+ Ports and 10G Uplinks
The Netgear M4300-28G-PoE+ (GSM4328PB-100NES) represents the cutting edge in connectivity solutions for businesses seeking enterprise performance, flexibility, and simplified management. Designed as part of the renowned Intelligent Edge series, this Layer 3 (L3) managed switch is the ideal backbone for modern converged networks, integrating voice, video, and data with absolute reliability.
This device stands out for its Non-Stop Forwarding (NSF) architecture, which enables true, seamless stacking, eliminating single points of failure in the network. With a configuration of 24 Gigabit PoE+ ports capable of delivering up to 30W per port, it's perfect for powering a high density of devices such as Wi-Fi 6 access points, IP surveillance cameras, and VoIP phones without the need for additional electrical wiring. Its 630W power budget (with the included 110V power supply, expandable depending on voltage and modules) ensures your critical devices remain operational at all times.
Unlike other switches that share bandwidth across ports, the GSM4328PB offers four independent 10G uplink ports : two copper (10GBASE-T) and two fiber (SFP+). This enables a smooth and progressive transition to 10 Gigabit speeds, facilitating ultra-high-speed connections to servers, storage, or the network core without bottlenecks. Furthermore, its modular design with hot-swappable power supplies ensures business continuity through redundancy.
Main features
-
10G Hybrid Connectivity: It has 2 10GBASE-T ports and 2 dedicated SFP+ ports, allowing high-speed links over both copper and fiber optics simultaneously.
-
High Power PoE+ Power: 24 ports with IEEE 802.3at support (30W per port) and a base power budget of 630W, ideal for demanding IoT deployments.
-
Advanced Stacking: Allows you to connect up to 8 switches in a virtual stack, managing them as a single logical entity with non-interruptible failover (NSF).
-
Complete Layer 3 Management: Includes static routing, RIP, VRRP, OSPF and PIM as standard, without the need to purchase additional software licenses.
-
Modular and Redundant Design: Full width (1U) chassis with two power supply bays, allowing 1+1 redundancy (RPS) or power expansion (EPS).
-
AV over IP Ready: Factory optimized for professional audio and video networks (ProAV) with "Zero Touch" configuration for multicast.
Benefits for the business environment
The M4300 series eliminates the complexity of advanced network deployments. For IT administrators, the ability to mix and match 1G and 10G models in the same stack greatly simplifies future scalability; you can start with a single switch and expand the network by adding units as needed, while maintaining centralized management. Hardware redundancy ensures that in the event of a power failure, the switch continues to operate without interrupting data traffic—a critical factor for hospitals, security centers, and corporate offices.
Furthermore, its optimization for AV-over-IP makes it the preferred choice for multimedia installations, ensuring that 4K/8K video traffic is transmitted without latency or artifacts thanks to the implementation of IGMP Plus and pre-configured profiles.
Use cases
-
IP Video Surveillance Networks: Power and data management for up to 24 high-definition IP cameras, with fast upload links for recording on NVR servers.
-
VoIP and Wi-Fi infrastructure: Mass deployment of IP phones and wireless access points in offices or university campuses, simplifying cabling.
-
ProAV Installations: Management of video matrices, video walls and digital signage in stadiums, auditoriums or conference rooms using SDVoE technology.
-
Network core for SMEs: Acting as a central switch (Core) thanks to its L3 routing capabilities and 10G links to servers and NAS storage.
Frequently Asked Questions
-
Are the 10G ports shared (combo) or dedicated?
They are fully dedicated and independent. You can use the two 10G RJ45 ports and the two 10G SFP+ ports simultaneously, along with the 24 Gigabit ports.
-
Does the switch come with a power supply?
Yes, the GSM4328PB-100NES model includes a modular power supply (typically APS1000W). You can add a second unit separately for redundancy.
-
Is it necessary to purchase licenses to activate L3 routing?
No, the Layer 3 feature set (including OSPF and VRRP) comes unlocked out of the box and is included in the price.
-
What does a 630W PoE budget mean?
This is the total power available to run connected devices. With the included 110V power supply, it delivers 630W, and can reach 720W when connected to 220V or with dual power supply configurations.
Project description
Stackable 1U rackmount Layer 3 managed switch with 24 Gigabit Ethernet RJ45 ports supporting PoE+ (802.3at) and 4 dedicated 10 Gigabit uplink ports (2 x 10GBASE-T RJ45 and 2 x SFP+ Fiber). The unit integrates a 1000W modular power supply, providing a PoE budget of 630W (at 110V) to 720W (at 220V), expandable via a second bay for APS/EPS redundancy. It offers a switching capacity of 128 Gbps and native support for IPv4/IPv6 dynamic routing protocols (RIP, OSPF, VRRP, PIM) without additional licenses. It is compatible with Spine and Leaf topologies and stacking with Non-Stop Forwarding (NSF) technology for high availability.
