Product Description

The DGS-3420 Series of next generation Layer 2+ Gigabit switches delivers performance, flexibility, security, multi-layer QoS and access control, along with redundant power solutions for SMBs and enterprises. With high Gigabit port densities, Gigabit SFP and 10-Gigabit SF + support, and advanced software solutions, these switches can act as either departmental access layer devices or aggregation switches to form a multilevel network structured with backbone and centralised high-speed servers. Service providers can take advantage of the high SFP density switches to structure the aggregation of Fibre to the Building (FTTB) networks that they extend to the subscriber's sites.

Main Features:

  • Five different models in the Series, including PoE/PoE+ versions
  • Multiple functions in a single device: switching, routing, PoE, eliminating the need of purchasing multiple routers and switches
  • Physical stacking architecture: up to 576 Gigabit ports on a single stack
  • Web-based GUI for easy management
  • Comprehensive security features, including Microsoft NAP
  • Comprehensive IPv6 support
  • SD card slot to store and restore configuration files
  • Green technology - Power-saving mode, time-base PoE, Smart Fans
