D-Link xStack DXS- Switch ports EN Fast EN Gigabit EN Base-T Base-TX Base-T x shared SFP / x XFP / x Expansion Slot empty U stackable Marketing Description D-Links xStack series Switches are designed to provide effortless wireless technology convergence with traditional Layer data access switching emphasizing on security performance and resiliency. Featuring the latest stacking technology from D-Link the xStack DXS- can stack up to units providing up to Gigabit ports and a total aggregated bandwidth of up to . Terabits. It can stack with other D-Link switches advocating extraordinary flexibility. It provides built-in copper Gigabit ports including combo SFP ports for easy flexible connection to fiber-based Gigabit media. The DXS- is also equipped with module slots that support Gigabit Ethernet for both copper CX- and fiber XFP connections as well as fixed GbE XFP port for a total switching capacity of up to Gbps. In addition the DXS- also supports IP static routing VLANs up to trunk groups and is wireless-ready making the DXS- the most feature rich high capacity switching solution in its class by far.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- is capable of meeting this demand and more. With a simple optional firmware upgrade the DXS- transforms from a standard Layer 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 is 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 G/VOIP mobile phones. With an optional software upgrade the DXS- functions as a wireless switch providing secure seamless roaming between access points ensuring clear uninterrupted data and voice communication throughout your wireless network infrastructure.The DXS- 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 .x authentication login. In addition port based security can also be set up to protect the integrity of the network. Furthermore the DXS- protects against attacks towards the CPU itself and improves utilization to meet existing network demands to maximize device responsiveness to user configuration activities.The DXS- supports 'Shortest-Path' switching which improves resiliency uptime and network efficiency. It also supports an optional Redundant Power Supply DPS- . It includes support for
