MODEL- DXS-3350SR         VENDOR- D-LINK
  
FEATURES- DXS3350SR-DLINK - X Stack Stackable, high-speed, rack-mount Switch- (48) 10/100/1000 Ports with (4) 
       Combo SFP Slots, (2) 10-Gig Stacking Ports, and (2) Optional 10-Gig 
       Uplinks. Includes DEM-CB50 50cm 10-Gig stacking cable.
       D-Links xStack Series is a set of "Next Generation" high performance 
        stackable switches that deliver high scalability, wire-speed 
        Gigabit performance, high availability, integrated 10-Gigabit 
        stacking, redundant power option, and support for stacking in a 
        "ring" or "star" topology (requires DGS-3324SRi as stacking 
        master). The xStack DXS-3350SR provides 48 built-in copper Gigabit 
        ports, including (4) Combo SFP ports supporting either copper links 
        or SFP modules for easy, flexible connection to fiber-based Gigabit 
        media. In a ring stack it can provide up to 384 Gigabit ports, up 
        to 40Gbps of stacking bandwidth per switch, and a switching 
        capacity of up to 176Gbps per unit. It also stacks with the other 
        xStack Series switches including the DGS-3324SR, DGS-3324SRi, and 
        DXS-3326GSR to provide unprecedented flexibility in a switch stack 
        environment.
* HIGH AVAILABILITY
   The xStack DXS-3350SR in a ring stacking topology supports "Shortest-
   Path, Fail-Safe" switching which improves resiliency, uptime and network 
   efficiency. It also supports an optional Redundant Power Supply 
   DPS-500) and includes support for 802.3ad Link Aggregation, 802.1d 
   Spanning Tree, 802.1w Rapid Spanning Tree, and 802.1s Multiple Spanning 
   Tree for increased network reliability and availability.
* NETWORK MANAGEMENT
   An extensive set of network management features is supported including 
   console CLI, telnet, Web, SNMPv1/v2/v3, RMON, TFTP, Port Mirroring, 
   BootP, and DHCP. The switch can also be easily managed using D-Links 
   SIM (Single IP Management) Clustering technology. It also supports a 
   variety of advanced traffic management options including 802.1x, 
   Bandwidth Control, Broadcast Rate Limiting, and support for IGMP 
   Snooping v1/v2/v3.
* ADVANCED ENTERPRISE FEATURES-
   The DXS-3350SR supports a robust and consistent set of QoS/CoS, VLAN, 
   and security features. It provides 8 priority queues for 802.1p/ToS/
   DiffServ, with classification and marking based on MAC SA/DA, IP SA/DA, 
   and/or TCP/UDP port numbers. Layer 3 dynamic routing protocols include 
   RIPv1/v2, OSPFv2, PIM-DM/SM, DVMRP, and VRRP. Security features include 
   802.1x (Port-based Authentication), 802.1x (MAC-based Authentication), 
   and Access Control Lists (ACL) based on MAC address, IP address, and/or 
   TCP/UDP port numbers. It also provides extensive support for GARP/GVRP, 
   802.1q, 802.1v IPv6 VLAN, and port-based VLANs for up to 255 static 
   groups per device.
   The xStack DXS-3350SR is the latest example of D-Links continued 
   commitment to our channel partners and customers to be the industry 
   leader in delivering cost-effective, reliable, high performance, 
   feature-rich switch solutions.
