Netgear GS748TS-100NAS ProSafe 48-Port Gigabit Stackable Smart Switch

The Netgear GS748TS-100NAS has the ability to stack up to six units and 288 ports and manage them all from a single IP address. Growing companies rely on their network to provide the foundation for essential business applications: mission-critical data applications, security, Voice over IP (VoIP), video-conferencing and much more. Businesses that are growing rapidly want full-featured network switches that can accommodate growth, support the full range of network applications and secure the network without the overhead and complexity of fully-managed switches. The ProSafe Gigabit Stackable Smart Switch family delivers the scalability, flexibility, reliability, and performance growing small and medium-sized businesses need in an affordable and easy-to-manage package.

Netgear GS748TS-100NAS ProSafe 48-Port Gigabit Stackable Smart Switch with 4 Built-in Shared SFP Gigabit Ethernet Fiber Ports for 100/1000 Mbps Connectivity

A first in the industry, each ProSafe Gigabit Stackable Smart Switch comes with 24 or 48 10/100/1000 ports with four shared SFP ports that provide high performance for bandwidth intensive applications like ERP and large file transfers. In addition, two dedicated ports provide a 20 Gbps, dual-ring, stacking bus that accommodates growth and offers the highest level of resiliency, thus allowing you to stack up to six switches or 288 10/100/1000 ports - and easily manage them all with a single IP address. Finally, these Netgear 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), 802.1x port authentication, enhanced QoS, rate limiting and IGMP Snooping among others to provide a small and medium-sized business with a network that is geared for growth while providing scalability and reliability. An intuitive, web-browser interface provides simple yet comprehensive management, making it a snap to fully realize the potential of the rich feature-set offered by these switches. Why buy fully managed stackable network switches designed and priced for the enterprise? NETGEAR ProSafe Gigabit Stackable Smart Switches are designed for small and medium-sized growing businesses. Scalability and High Availability
Each ProSafe Gigabit Stackable Smart Switch comes with 2 dedicated high-speed stacking ports providing 20 Gbps of bandwidth. Stack as many as six switches as you grow, and yet maintain high-speed connectivity across the stack with stacking cables. This stacking technology also provides several high-availability features to ensure business continuity:
