The DES-3528/3552 xStack series are enhanced L2+ access stackable switches designed to connect end-users  in a secure SMB  (small and medium size business) or enterprise network. These switches provide physical stacking* , static  routing* , multicast and enhanced  security, making  it an  ideal access  layer solution. The DES-3528/3552 xStack Series can seamlessly integrate with L3 core switches to form a multi-level network structure consisting of a high-speed backbone and centralized servers.

Flexible & Cost-Effective Ethernet Stack. The DES-3528/3552 series provide  the option of 24 or 48 10/100Mbps Ethernet ports and up to four Gigabit uplinks per switch. Users requiring connections to devices such as IP phones, network cameras and wireless APs can deploy the DES-3528P, which provide 24 10/100Mbps PoE ports. Eight of  these PoE ports provide up to 30watts per port, while  the  remaining adhere  to  the 802.3af standard  (15.4watt output per port), giving administrators the ability to connect to the 802.3af standard devices as well as the 802.3at pre-standard equipment such as  the 802.11n AP. The  two combo 10/100/100BASE-T SFP slots on  the  front panel provide  flexible copper or  fiber Gigabit connection. The  two 10/100/1000BASE-T ports on  the back panel are designed  for fexible dual usage. They can be used either as stacking ports with 4Gbps bidirectional stacking bandwidth, or can simply be used as copper Gigabit uplinks. Physical stacking*  capability allows administrators  to add up to eight switch units per stack on a scalable expansion basis. This series offers an attractive stackable switch alternative to the expensive chassis-based solution.

Comprehensive Security. The DES-3528/3552 series provide users with  the  latest security features such as 802.1X Guest VLAN, MAC-based Access Control  (MAC) and Web-based Access Control  (WAC). 802.1X Guest VLAN  is a comprehensive end-point security solution for user authentication/authorization and WAC guarantees granular network access control with a user-friendly authentication mechanism. The  IP-MAC-Port Binding  feature allows administrators  to bind a source  IP address with an associated MAC and also  to define  the port number  to enhance user access control. And with DHCP Snooping  feature,  the switch automatically  learns  the  IP/MAC pairs by snooping DHCP packets and saving  them  to  the IMPB white  list. This keeps  the network secure and auditable. The D-Link Safeguard Engine identifes and prioritizes "CPU interested" packets to prevent malicious traffc from interrupting normal network fows and protects switch operation.

Enhanced Network Performance & Availability. The DES-3528/3552 series  targets SMB/enterprise customers who  require a high  level of network security and maximum uptime.  It offers Static Route*, 4K VLAN, advanced selective Q-in-Q, as well as delivering progressive QoS capability  for mission-critical applications and multicast services. The switches offer superior performance and availability  through  the  latest Spanning Tree protocol, optional redundant power, and Loopback Detection (D-Link's advanced technology for preventing loops without the presence of STP).

User-friendly & Ecosystem-friendly. The DES-3528/3552 series uses D-Link's Web GUI 2.0, an easy-to-use web  interface, and confguration wizards  to minimize administrators'  learning curve and make deployments easier  to plan and  implement. Utilizing  the  latest generation of chipsets, the DES-3528/3552 series optimizes power consumption to reduce energy costs and contribute  to a greener environment.  In addition,  its  fanless design ensures quiet operation, ideal for deployment in open spaces.

* Physical Stacking and Static Route are planned for future releases
