DGS-3620 Series
xStack L3 Managed Stackable Gigabit Switches
The xStack DGS-3620 Series of next-generation Layer 3
Gigabit switches deliver performance, flexibility, security,
multi-layer QoS, and accessibility, along with redundant
power solutions for SMBs and enterprises. With high
Gigabit port densities, Gigabit SFP, and 10-Gigabit
SFP+ support, and advanced software solutions, these
switches can act as either departmental access layer
devices or core switches to form a multilevel network
structured with backbone and centralized high-speed
servers. Service providers can take advantage of the
high SFP density switches to structure the cores of Fiber
to the Building (FTTB) networks that are extended to the
subscribers’ sites.
Standard and Enhanced Images
The DGS-3620 Series is embedded with two different
software images, the Standard Image (SI) and the
Enhanced Image (EI). The Standard Image provides
fundamental features for campuses and enterprises
such as switching, routing, multicasting, advanced
Quality of Service (QoS), and robust security features.
The Enhanced Image supports OAM, BGP, IPv6 dynamic
routing, and tunneling which are all suitable for the
service provider network.
Unparalleled Flexibility
Easily deployed and simple to manage, the DGS-3620 can
be stacked with any switch that supports D-Link’s Single
IP Management to form a multi-level network structured
with backbone and centralized 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 traffic at 20 Gbps full duplex
speeds. The stack can also eliminate single point of
failures, 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 stack.
12 units or 576 Gigabit ports can be configured for a stack
using direct attach cables providing high-bandwidth on
the already cost-efficient DGS-3620 Series.
Security, Performance & Availability
The DGS-3620 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. D-Link ZoneDefense technology is
built-in, allowing businesses to integrate the switch
stack with D-Link NetDefend firewalls to implement a
complete and proactive security infrastructure.
The DGS-3620 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-3620 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-3620 Series also features comprehensive
IPv6 support, including IPv6 Tunnel, ICMPv6, DHCPv6,
RIPng, OSPFv3, IPv4/IPv6 dual stack and more. With
10-Gigabit connectivity and IPv6 support, the DGS-3620
Series enables you to future-proof your network for cost
efficiency and longevity while meeting the requirements
that future IPv6 capable network devices require.
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-3620 Series implements D-Link Green technology,
which includes a power saving mode, smart fan feature,
reduced heat dissipation, and cable length detection.
The power saving feature automatically powers down
ports that have no link or link partner. The Smart Fan
feature allows for the built-in fans to automatically turn
on only at a certain temperature, providing continuous,
reliable and eco-friendly operation of the switch.
