Switches Designed For Scalability and Improved Resiliency

Enhanced Scalability and Network Convergence for Growing Businesses

The ProSAFE® Stackable Smart Switch series is unique in delivering the scalability, reliability, and performance growing small and medium-sized businesses need in an affordable and easy-to-manage package. The second generation of these Stackable Smart Switches consists of 4 models in 28/52-port configurations. Each switch in the series comes with a total of 6 SFP ports for fiber connectivity. Among them, 2 are shared, and the other 4 are dedicated for either stacking or uplinks. This new generation of Stackable Smart Switches offers two models that support PoE+ (up to 30W per port) allowing more flexible network deployments of PoE devices. The ProSAFE® Stackable Switch series offers the flexibility and scalability that will make it easier for growing businesses to seamlessly expand their network capacity.


Stacking for Scalability and High Availability

The new Generation of Stackable Smart Switches use 2 dedicated ports in the front of the switch for stacking, providing a 10Gbps, dual-ring, highly redundant stacking bus that carries intra-stack traffic and provide highest level of resilience, allowing you to stack up to six switches or up to 300 10/100/1000 Mbps ports, forming a virtual chassis for easy management under a single IP address. This stacking technology also provides several high-availability features to ensure business continuity:

Resiliency: Due to redundant stacking port connections, there is an automatic fail-over in case any switch in the stack fails, with rapid reconfiguration, thus preventing network downtime.

Hot-swappable: All switches in the stack are hot-swappable, and can be integrated or removed without disrupting the network.

Comprehensive and Advanced Feature Sets

These Stackable Smart Switches come with a complete suite of advanced features for more robust security, higher quality of service and high availability. This switch is equipped with highly advanced features such as access control lists (ACL), static routing, rate limiting,IGMP snooping, and Dynamic VLAN assignment among others to provide a small and medium-sized business with a network that is geared for growth and new network applications. Friendly to converged network with voice and video, the Stackable Smart Switches offers auto voice and auto video features that automatically configures QoS, security and VLAN settings for IP phones and IP cameras.

IPv6 Support


In order to accommodate the move by internet service providers to IPv6 addresses, the 2nd Generation of Gigabit Stackable Smart Switches expand the IPv6 support beyond management only to QoS, ACL and multicast. It means that your network will benefit from the IPv6 enhancements and is future-proofed.

Manageability and Support

There are various easy and convenient ways to manage the Stackable Smart Switch. The new Stackable Smart Switches can be managed by the Smart Control Center software which comes free with the switch. With it, you can discover and manage all NETGEAR Smart Switches from a central location, conduct mass configuration and firmware upgrade. If you have other NETGEAR business products in your network, you can also use the NMS200, NETGEAR's management platform for discovery and configuration of all your NETGEAR products in the network. For peace of mind, these Stackable Smart Switches are backed by the NETGEAR ProSafe Lifetime Hardware Warranty and 1-year 24x7 Advanced Technical Support*.
