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, 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 multilevel
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 provides 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 flexible 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 define the
port number to enhance user access control. With the DHCP Snooping feature, the switch automatically
learns 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 identifies and prioritizes "CPU interested"
packets to prevent malicious traffic from interrupting normal network flows 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 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 configuration
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, the fanless design of the
DES-3528 and DES-3528DC ensures quiet operation, ideal for deployment in open spaces. The DES-3528P and DES-3552 are equipped with a Smart Fan feature. This feature allows for the built-in fans to automatically turn on at a certain temperature, providing continuous, reliable and eco-friendly operation of the switches.
