Switch DES-3528, 24x10/100Base-TX Ports, 12.8Gbps, L2, 4 Gigabit Ports and 2 Combo SFP
The DES-3528 xStack® 24-port Managed Layer 2 switch is ideal for light to medium voice, video and data applications and features advanced QoS, network management and security.
The xStack® DES-3528 by D-Link is a high-performance, managed, stackable Layer 2 switch 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 DES-3528 dispersed switches with fewer distance limitations through a single IP address. The clustering environment spans buildings, making it perfect for businesses that require multiple building deployments. The DES-3528 also supports physical stacking of up to 8 units in a stack, so that the entire stack can act as a single logical unit with up to 4Gbps of stacking backplane. The xStack switch also provides comprehensive security for edge access such as Access Control List, DHCP server screening and DoS attack prevention.
Non-Blocking Switching
The 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 Security
For 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.
The xStack switch also supports loopback detection, which detects a loop in the network even though the end device causing the loop is without spanning tree. When the switch detects a loop is in the connected node, the DES-3528 shuts down the port with the loop so that the entire system will continue to function normally. This feature can also be VLAN based.
