xStack L2+ Managed Gigabit Switches

DGS-3420 Series

™

The xStack DGS-3420 series of next generation Layer 2+ Gigabit switches delivers performance,

exibility, security, multi-layer QoS, and accessibility, along with redundant power solutions 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 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 (DGS-3420-28SC) to

structure the aggregation of Fiber to the Building (FTTB) networks that are extended to the

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 structured with

backbone and centralised high-speed servers. The virtual stack can include units located

anywhere on the same network domain, and uses optional 10-Gigabit uplinks to move intra-

stack trac at 20 Gbps full duplex speeds.

Redundant Ring Stacking

Alternatively, depending on whether linear or fault-tolerant 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 congured for a stack using direct attach cables to provide high bandwidth on the

DGS-3420 Series with cost eciency.
