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 trac 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 congured for a stack using direct attach cables to provide high bandwidth on the
DGS-3420 Series with cost eciency.
