Product Highlights
Overview
The xStack DGS-3420 series of next generation Layer 2+ Gigabit switches delivers
performance, flexibility, security, multi-layer QoS, and accessibility, along with redundant
power options for SMBs and enterprises. With high Gigabit port densities, Gigabit SFP,
10-Gigabit SFP+ support, and advanced software solutions, these switches can act as either
a departmental access layer or aggregation switches to form a multilevel network. Service
providers can take advantage of the high SFP density (DGS-3420-28SC) to structure the
aggregation of Fiber to the Building (FTTB) networks that can be extended to subscribers’
sites.
Unparalleled Flexibility
Easily deployed and simple to manage, the DGS-3420 can be stacked with any switch that
supports D-Link’s Single IP Management to form a multi-level network with centralized
management. The virtual stack can include units located anywhere on the same network
domain and uses optional 10-Gigabit uplinks to move intra-stack traffic at 20 Gbps full
duplex speeds.
Redundant Ring Stacking
Alternatively, depending on whether linear or ring stacking is implemented, users can use
one or two 10-Gigabit SFP+ ports to create a physical stack. 12 units or 576 Gigabit ports can
be configured for a stack using direct attach cables to provide high-bandwidth and return
on investment.
