The DGS-3620 Series xStack L3 Managed Stackable Gigabit Switches deliver great
performance, exibility, 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 dierent 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 Series 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 trac 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.
OAM
• 802.3ah Ethernet link OAM
• 802.1ag, ITU-T Y.1731 service OAM
xStack L3 Managed Stackable Gigabit Switches
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 providing high bandwidth on the already cost-
ecient 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
rewalls to implement a complete and proactive security infrastructure.
The DGS-3620 Series oers 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 ooding trac
caused by worms or virus infections. Bandwidth Control can be exibly set
for each port using pre-dened thresholds to assure a committed level of
service for end users. For advanced applications, ow-based bandwidth
control allows easy ne-tuning of service types based on specic IP addresses
or protocols.
DGS-3620 Series
If the worst should happen to your network you need the very best
support and fast. Downtime costs your business money. D-Link
Assist maximises your uptime by solving technical problems
quickly and eectively. Our highly trained technicians are on
standby around the clock, ensuring that award-winning support
is only a phone call away.
With a choice of three aordable service oerings covering all
D-Link business products, you can select the package that suits
you best:
D-Link Assist Gold - for comprehensive 24-hour support
D-Link Assist Gold is perfect for mission-critical environments
where maximum uptime is a high priority. It guarantees four hour
around-the-clock response. Cover applies 24/7 for every day of the
year including holidays.
D-Link Assist Silver - for prompt same-day assistance
D-Link Assist Silver is designed for ‘high availability’ businesses that
require rapid response within regular working hours. It provides a
four hour response service Monday to Friday from 8am to 5pm,
excluding holidays.
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 eciency 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 sacrice 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 temperature4, providing
continuous, reliable, and eco-friendly operation of the switch.
D-Link Assist Bronze - for guaranteed response on the
next business day
D-Link Assist Bronze is a highly cost-eective support solution for
less critical environments. Response is guaranteed within eight
business hours Monday to Friday from 8am to 5pm, excluding
holidays.
D-Link Assist can be purchased together with any D-Link business
product. So whether you’re buying switching, wireless, storage,
security or IP Surveillance equipment from D-Link, your peace
of mind is guaranteed. D-Link Assist also oers installation and
conguration services to get your new hardware working quickly
and correctly.
