FEATURES- ProSafe 48-port Gigabit Stackable Smart Switch
       ProSafe 48-port Gigabit Smart Stackable Switch with 4 shared SFP 
        Ports!
       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. 
       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 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. 
    Includes ProSafe 48-port Gigabit Smart Stackable Switch with 4 shared 
      SFP Ports, Rubber footpads, Power cord, One stacking cable, Rack-
      mount kit, Resource CD Installation Guide, Warranty/Support 
      information card.
* 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: 
    - 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. 
* Advanced Security 
   These switches also provide advanced features that provide more robust 
   security to the SMBs. These include: 
    - 802.1x for authentication 
    - ACL filtering to permit or deny traffic based on MAC addresses. 
* Advanced Quality of Service (QoS) 
   Priority queuing ensures high-priority traffic gets delivered 
   efficiently, even during congestion from high traffic bursts. Companies 
   implementing network telephony or video conferencing, for example, need 
   to be able to prioritize such voice and video traffic and other real-
   time applications over less latency-sensitive traffic to ensure 
   reliability and quality. The ability to prioritize traffic ensures 
   quality of latency-sensitive services and applications despite 
   increasing traffic loads. The ProSafe Gigabit Stackable Smart Switches 
   provide an extensive set of QoS features: 
    - 802.1p based prioritization 
    - Layer 3-based (DSCP) prioritization 
    - Rate-limiting 
* 'Smart' Management features 
   Manage all ProSafe Gigabit Stackable Smart Switches as though they are 
   one unit from an easy-to-use Web console that can be used to configure 
   all features, as well as monitor and trouble-shoot. These switches also 
   have SNMP (v1, 2 and 3) to collect and track data to monitor the network 
   health, as well as manage devices, and more easily enforce critical IT 
   controls and policies. SNMP v2c is most commonly deployed, as it 
   provides better reporting capabilities than SNMP v1. Companies 
   interested in more robust security may opt for SNMP v3, which provides 
   data encryption. 
   All ProSafe Gigabit Stackable Smart Switches provide world-class 
   reliability with a Limited Lifetime warranty and optional ProSupport 
   Maintenance Packages. These switches are optimized for ProSafe Network 
   Management Software (NMS100) and works with other SNMP-based management 
   software.
