The xStack DES-3528 by D-Link is a high-performance, managed, stackable 28-port Layer 2 Fast Ethernet switch including 2 Gigabit Ethernet and 2 Combo 1000BASET-T/SFP ports that provides an ideal solution for workgroups and edge deployments of a network. The D-Link Single IP Management (SIM) allows administrators to cluster up a virtual stack of up to 32 dispersed switches with fewer distance limitations through a single IP address.Non-Blocking SwitchingThe DES-3528 provides a non-blocking switching solution for 10/100 Fast Ethernet connections. The DES-3528 supports 24 10/100Mbps ports, with 4 gigabit 10/100/1000BASE-T ports. Two of these gigabit copper ports are disabled when the two 1000BASE-X SFP are used, also known as dual personality or combo ports. The DES-3528 has a non-blocking bandwidth of 12.8Gbps; the xStack switch has a redundant power option for mission critical applications.Advanced Network SecurityFor edge network security, the DES-3528 supports DHCP server screening, client filtering, and IP-MAC-Port Binding to prevent security breaches such as rogue DHCP server, man-in-the-middle attacks and IP spoofing. For clients with XP SP3, Vista, or servers with Microsoft’s Server 2008, DES-3528 works in conjunction with Microsoft’s Network Access Protection (NAP) as part of an ecosystem that enforces compliance with network health policies. The xStack switch will grant network host access only if it complies with IT security policies such as up-to-date anti-virus signatures and operating system patches. This prevents a virus-infested client or server from gaining access and further contamination.
