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.
Unparalleled Flexibility
Easily deployed and simple to manage, the DGS-3420 can be virtually
stacked with any switch that supports D-Link’s Single IP Management
(SIM) 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, eliminating cable distance
barriers, limitations of physical stacking, and the need for stack
cabling.
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 stack1. Switches in the stack are
hot-swappable to minimise network downtime in case a replacement is
required, eliminating single points of failure. Up to 12 units or 576
Gigabit ports can be configured for a stack using direct attached
cables1 allowing high bandwidth and high port densities on the already
cost efficient DGS-3420 Series.
Security, Performance & Availability
The DGS-3420 Series provides a complete set of security features
including L2/L3/L4 multi-layer Access Control Lists and 802.1x user
authentication via TACACS+ and RADIUS servers.
The DGS-3420 Series offers extensive VLAN support including GVRP and
802.1Q VLAN to enhance security and performance. A robust set of
L2/L3/L4 QoS/CoS solutions help ensure that critical network services
such as VoIP, ERP, Intranet, and video conferencing are served with
proper priority. The DGS-3420 Series provides D-Link’s Safeguard Engine
to increase the switch’s reliability, serviceability, and availability
to prevent malicious flooding traffic caused by worms or virus
infections. Bandwidth Control can be flexibly set for each port using
pre defined thresholds to assure a committed level of service for end
users. For advanced applications, flow-based bandwidth control allows
easy fine tuning of service types based on specific IP addresses or
protocols.
IPv6 Technology
The DGS-3420 Series also features comprehensive IPv6 support,
including IPv6 Tunneling, ICMPv6, DHCPv6, RIPng, etc. With 10-Gigabit
connectivity and IPv6 support, the DGS-3420 Series enables you to future-proof
your network for cost efficiency and longevity while meeting the
requirements for IPv6 capable network devices in the coming years.
D-Link Green Technology
D-Link is striving to take the lead in developing innovative and
power-saving technology that does not sacrifice operational performance
or functionality. The DGS-3420 Series implements the D-Link Green
Technology, which includes a power saving mode, smart fan, reduced heat
dissipation, and cable length detection. The power saving feature
automatically powers down ports that have no active link. The Smart Fan
feature allows for the built-in fans to automatically turn on at a
certain temperature, providing continuous, reliable and eco-friendly
operation of the switch.
