FEATURES- ProSafe 48-port Gigabit Layer 3 Managed Stackable Switch
       ProSafe 48-port Gigabit Layer 3 Managed Stackable Switch with (4)
        10-Gigabit slots.
       NETGEAR's low-cost, stackable, Gigabit Ethernet switches deliver 
        maximum throughput and flexibility where you need it -- to high-
        speed, high-density workgroups at the edge of the network, in the 
        backbone of growing networks or for bandwidth thirsty file and 
        application servers. The ProSafe GSM7328S and GSM7352S fully 
        managed switches deliver 24 and 48 ports of auto-sensing 
        10/100/1000 Mbps interfaces for high-density copper connectivity. 
       Four (GSM7328S) or eight (GSM7352S) hot-swappable Small Form-factor 
        Pluggable (SFP) gigabit interfaces provide optional fiber 
        connectivity for longer reach Gigabit Ethernet requirements. 
        Additionally, four high-speed module bays offer modular expansion 
        for 10 Gigabit Ethernet or 24 Gigabit Stacking connectivity. The 
        non-blocking design of the switches delivers simultaneous, full 
        wire-speed, low-latency throughput to all ports.
       A full suite of Layer 3 switching functionality ensures reliable 
        routing between VLANs and network segmentation where and when you 
        need it, at no additional cost. By configuring the switches into a 
        stack of up to 8 units across a 48 Gbps bi-directional ring, a 
        high-density, single IP-addressable switch can be built. 
       Robust security features include IEEE 802.1x port-based 
        authentication and access control lists, ensuring that only 
        authorized users can access your network. Secure management of the 
        switches is available through Secure Sockets Layer (SSLv3) for the 
        Web GUI and Secured Shell (SSH) for command-line sessions. 
        Additionally, multiple switches can be securely managed via SNMPv3 
        with NETGEAR's ProSafe Network Management Software NMS100. For 
        workgroup deployments in cost-sensitive organizations that require 
        Layer 3 switching, additional Gigabit capacity, high-value price 
        point, flexibility of stacking, and reduced maintenance 
        requirements, NETGEAR's ProSafe 10/100 Layer 3 Stackable switches 
        deliver the ideal access-edge solution. 
       With their high-value price point, flexible design, and reduced 
        maintenance requirements, NETGEAR's ProSafe 10/100/1000 Layer 3 
        Stackable switch solutions yield a high return on investment, and 
        are ideal for delivering highly reliable, converged voice, video, 
        and data services over a single network infrastructure. 
    Includes ProSafe Managed Switch, Null modem cable, Rubber footpads,
      Power cable, Rack-mount kit, Installation guide, Resource CD-ROM with
      30-day trial of NMS100, Warranty/Support information card.
* POWERFUL
   In desktop switching environments, wire-speed performance with full QoS 
   control for all 10/100/1000 interfaces is critical. The 4 high-speed 
   10G/24G module bays provide unprecedented flexibility, whether you are 
   stacking between switches, attaching bandwidth-thirsty file servers, or 
   aggregating critical data to the core of your network.  
* EASY-TO-USE
   Simplify and reduce IT staff workload and mean time-to-repair with 
   intuitive, GUI-based device configuration, and an industry-standard 
   command-line interface (CLI). Stacking capabilities allow you to build a 
   single- IP manageable device with up to eight switches utilizing ultra-
   high-speed 24 Gigabit stacking cables to deliver 48Gbps across an 
   intelligence bi-directional redundant interconnect.
