Description
Unparalleled Flexibility
Easily deployed and simple to manage, the DGS-3420 can be virtually stacked with
any switch that supports D-Links 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
cables** 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-Links Safeguard Engine to increase the switchs 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
Tunnelling, 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. The Time Based PoE feature allows to create a schedule
when the PoE delivery can be disabled and save more energy.
* PoE power budget can be increased from 370W to 740W with optional DPS-700
