Description

D-Link's DES-3250TG is a high performance managed Layer 2 auto-sensing 10/100BASE-T switch that provides an ideal solution for high density Enterprise applications. With (48) 10/100BASE-T Ethernet ports and (2) combo 10/100/1000BASE-T/SFPs (mini-GBIC) ports, the DES-3250TG is designed to meet the needs of the most demanding departmental and enterprise connectivity applications requiring a high density, low profile solution.

D-Link’s DES-3250TG is a high performance managed Layer 2 auto-sensing 10/100BASE-T switch that provides an ideal solution for high density Enterprise applications. With (48) 10/100Mbps Ethernet ports and (2) combo 10/100/1000Mbps/SFPs (mini-GBIC) slots, the DES-3250TG is designed to meet the needs of the most demanding departmental and enterprise connectivity applications requiring a high density, low profile solution.

High Performance Wire-Speed Architecture
The DES-3250TG supports full-duplex wire-speed forwarding, 8,000 MAC addresses, 255 VLANs, and the ability to prioritize traffic into (4) priority queues. The DES-3250TG can be used as a cost effective, high density wiring closet solution or a high performance backbone aggregation device.

Network Management
D-Link’s DES-3250TG looks to address today’s diverse business and IT requirements through its robust support of standards-based network management protocols (CLI/SNMP/RMON/BOOTP/Telnet/Web) and port mirroring. By supporting standards-based network management protocols, the DES-3250TG can be easily integrated into most third-party network management products.

Advanced Enterprise Features
The DES-3250TG brings advanced Enterprise functions to a new level of affordability without compromising advanced features like: 802.3ad (link aggregation), 802.1x (authentication), QoS/CoS, Multicast, VLANs, Port Trunking, and Network Management. These features facilitate the deployment of business critical applications across an Enterprise, including: VOIP, streaming media, and multicast content delivery (IP video, software deployment…etc).

Investment Protection
With its wire-speed architecture and high density, low profile 1U design, the DES-3250TG is an ideal solution for today’s over crowded wiring closets. By supporting SFP/mini-GBIC modules, customers can migrate to other, more advanced solutions in the future, while still protecting a portion of their original investment.
