MODEL- DXS-3250-TAA       VENDOR- D-LINK
    
FEATURES- X Stack 3200 Series Switch
       Stackable, High-speed, Rack-mount, Managed  Wireless-Ready  Layer 2 
        Switch with (48) 10/100/1000Mbps Ports, (4) Combo SFP Ports & (2) 
        Optional 10-Gig Copper/Fiber Uplinks; Assembled in USA.
       D-Links xStack 3200 series Switches are designed to provide 
        effortless wireless technology convergence with traditional Layer 2 
        data access switching, emphasizing on security, performance, and 
        resiliency. Featuring the latest stacking technology from D-Link, 
        the xStack DXS-3250 can stack up to 16 units in a stack providing 
        up to 768 Gigabit ports. It can stack with other D-Link switches 
        such as the (DXS-3227, DXS-3227P), providing extraordinary 
        flexibility. It provides 48 built-in copper Gigabit ports, 
        including (4) combo SFP ports for easy, flexible connection to 
        fiber-based Gigabit media. The DXS-3250 is also equipped with 2 
        module slots that support 10 Gigabit Ethernet for both copper CX-4 
        and fiber XFP connections. When stacking through CX-4 interfaces, a 
        stacking bandwidth of 48Gbps can be achieved, for a total switching 
        fabric capacity of up to 144Gbps. In addition, the DXS-3250 also 
        supports IP static routing, 4000 VLANs, up to 64 trunk groups, and 
        is  wireless-ready , making the DXS-3250 the most feature rich, 
        high capacity switching solution in its class by far.
* Wireless Ready
   In a mixed network of wired and wireless environments, predictable 
   coverage and security become paramount. The need for a switching 
   solution capable of addressing these needs in both the wired and 
   wireless environment becomes key. The DXS-3250 is capable of meeting 
   this demand and more. With a simple optional firmware upgrade, the 
   DXS-3250 transforms from a standard Layer 2 switch into an integrated 
   wired and wireless switching solution capable of providing powerful 
   wireless security, easy deployment, the ability to detect rogue access 
   points, and centralized management for all compatible WLAN components. 
   Centralized management has become crucial for wireless technologies 
   deployed in real-time inventory, data mining, and an array of personal 
   electronics that demands mobility and seamless integration such as PDA 
   and 3G/VOIP mobile phones. With an optional software upgrade, the 
   DXS-3250 becomes a wireless switch providing secure, seamless roaming 
   between access points ensuring clear, uninterrupted data and voice 
   communication throughout your wireless network infrastructure.
* Comprehensive Security
   The DXS-3250 is equipped to handle many of todays emerging security 
   vulnerabilities previously delegated to only stand-alone firewalls. It 
   incorporates built in ACLs for searching out and filtering such threats 
   as: Denial of Service attacks, Trojan Horses, Worms, and more. Other 
   access rules can also be set up to prevent network, and 802.1x 
   authentication login. In addition, port based security can also be set 
   up to protect the integrity of the network. Furthermore, the DXS-3250 
   protects against attacks towards the CPU itself, and improves 
   utilization to meet existing network demands to maximize device 
   responsiveness to user configuration activities. In addition, well-known 
   port numbers for allowed applications can be pre-programmed, which will 
   allow these applications faster service, and reduce the load on the CPU.
* High Availability
   The DXS-3250 supports "Shortest-Path" switching which improves 
   resiliency, uptime and network efficiency. It also supports an optional 
   Redundant Power Supply (DPS-500). It includes support for 802.3ad Link 
   Aggregation, and 802.1w Rapid Spanning Tree for increased network 
   reliability and availability.
* Network Management
   The DXS-3250 features a variety of network management options: console 
   CLI, telnet, web GUI, SNMPv1/v2/v3, and RMON. It also supports a variety 
   of advanced traffic management options including: Layer 3 static 
   routing, Bandwidth Control, Broadcast Storm Control, Private VLANs, and 
   support for IGMP Snooping. D-Links exclusive stacking technology is also 
   supported, which allows up to 16 D-Link DXS-3250 switches to be stacked 
   together and managed as a single unit, regardless of its physical 
   environment.
* Advanced QoS
   The DXS-3250 provides a robust and consistent set of QoS/ CoS, 
   supporting 8 priority queues for 802.1p/ToS/DiffServ, with 
   classification and marking based on MAC SA/DA, IP SA/DA, and/or TCP/UDP. 
   It also provides extensive support for GARP/GVRP, 802.1q, and port-based 
   VLANs for up to 4000 groups per device.
