The xStack DES-3552 xStack switch is a enhanced L2+ access stackable switch designed to connect end-users in a secure SMB (small and medium size business) or enterprise network. This switch provides physical stacking1, static routing1, multicast and enhanced security, making it an ideal access layer solution.
The DES-3552 provides 48 Fast Ethernet ports and four Gigabit uplinks. 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 can be used either as stacking ports with 4 Gbps bidirectional stacking bandwidth, or simple copper Gigabit uplinks. Physical stacking1 capability allows administrators to add up to eight switch units per stack on a scalable expansion basis, an attractive alternative to the expensive chassis-based solution.
The DES-3552 switch provides administrators with extensive 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 address and a 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 identifies and prioritizes "CPU interested" packets to prevent malicious traffic from interrupting normal network flows and protects switch operation.
The DES-3552 series targets SMB/enterprise customers who require a high level of network security and maximum uptime. It offers Static Route1, 4K VLAN, advanced selective Q-in-Q, as well as delivering progressive QoS capability for mission-critical applications and multicast services. This switch offers 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).
The DES-3552 switch uses an easy-to-use web interface and configuration wizards to minimize an administrator's learning curve and make deployments easier to plan and implement. Utilizing the latest generation of chipsets, the DES-3552 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.
