D-Link’s DGS-1500 Series SmartPro switches are designed for SMBs which need functions
such as Static Routing and Single IP Management (Virtual Stacking). This series integrates
advanced management and security functions that are similar to those of a managed
switch, but less complex. The switches feature D-Link Green™ 3.0 technology which enables
significant power savings.
Management options include SNMP, Web Management, SmartConsole Utility, and Compact
CLI. The series also supports ACL filtering and D-Link’s Safeguard Engine. The DGS-1500-20
and DGS-1500-28 both feature a fanless design. The fanless design emits less noise than a
standard switch, increases the products’ lifetimes, and makes them better suited for office

the DGS-1500-28P is capable of providing up to 30 Watts on all ports when paired with
a DPS-700. The DPS-700 enables the DGS-1500-28P to have 1+1 power redundancy and
boosts the total PoE budget to 740 W. By itself, the DGS-1500-28P has a PoE power budget
of 370 W, allowing it to provide up to 15.4 W to all ports simultaneously. Time-based
PoE enables power to a port to be shut off at a scheduled time, reducing power usage
business hours.

D-Link Green™ 3.0 Technology
D-Link takes the lead in developing innovative and power-saving technology that does
not sacrifice operational performance or functionality. The DGS-1500 Series implements
D-Link Green™ 3.0 Technology, which includes a power saving mode, smart fans, reduced
heat dissipation, and cable length detection. The power-saving features include the ability
to schedule when to turn off LEDs and ports when not in use, and when to make the
switch enter hibernation mode. The switches also detect the length of connected cables
to automatically adjust power usage by saving energy on shorter cable connections of less
than 20 meters. The switches can also support power saving by link status, which drastically
reduces power consumption by automatically putting ports without a link into sleep mode.
The DGS-1500-28P and DGS-1500-52 both feature built-in smart fans that contribute to
continuous, reliable, and eco-friendly operation of the switch. Using a thermal sensor that
can detect temperature change, the fans can react accordingly by utilizing different fan
speeds for different temperatures.
Advanced Features
The DGS-1500 Series includes advanced features such as Virtual Stacking and Static
Routing. Virtual Stacking reduces the number of IP addresses needed on a network by
configuring up to 32 devices to appear as a single unit with one IP address. This simplifies
network management for small workgroups and allows for switches to be added without
special cabling. In static routing, IP routes are manually entered into a routing table, which
allows for communication between different user groups in different VLAN segments in
a network. The switch can directly handle inter VLAN routing using multiple interfaces,
making the network run faster and more efficiently. Because the switches can manage
internal routing, the network router can be assigned to handle external traffic routing only.
Extensive Layer 2 Features
These switches are equipped with a complete lineup of Layer 2 features including IGMP
Snooping, Port Mirroring, Spanning Tree, and Link Layer Discovery Protocol (LLDP). The
IEEE 802.3x Flow Control function allows servers to directly connect to the switch for fast,
reliable data transfer. At 2000 Mbps Full Duplex, the Gigabit ports provide high-speed data
pipes to servers with minimum data transfer loss. Network maintenance features include
Loopback Detection and Cable Diagnostics. Loopback Detection is used to detect loops
created by a specific port or VLAN and automatically shut down the affected port or VLAN.
The Cable Diagnostics feature, designed primarily for administrators and customer service
representatives, can quickly discover the type of error on cables and determine the cable
VLAN and Bandwidth Control
The DGS-1500 Series supports Auto Surveillance VLAN (ASV) and Auto Voice VLAN, which
are best suited for video surveillance and VoIP deployments. Auto Surveillance VLAN is
a new, industry-leading technology built into D-Link Smart Switches. This technology
consolidates data and surveillance video transmission through a single SmartPro switch,
thus sparing businesses the expense of maintaining dedicated hardware and facilities.
ASV also ensures the quality of real-time video for monitoring and control without
compromising the transmission of conventional network data. The Auto Voice VLAN
technology enhances VoIP service by automatically placing voice traffic from an IP phone
to an assigned VLAN with higher priority. This guarantees the quality and security of the
DGS-1500-20/28/28P/52 SmartPro Switch
VoIP traffic. Furthermore, the DSCP markings on Ethernet packets enable different
levels of service to be assigned to network traffic. As a result, these voice and
Versatile Management
The DGS-1500 series provides a SmartConsole utility and a web-based
video packets take precedence over other packets. In addition, with Bandwidth
management interface that enable administrators to remotely control their
Control, network administrators can reserve bandwidth for important functions
network down to the port level. The SmartConsole easily allows customers to
that require more bandwidth or might require higher priority.
discover multiple D-Link Smart Switches within the same L2 network segment.
With this utility, users do not need to change the IP address of their PC. It also
Secure your Network
D-Link’s innovative Safeguard Engine protects the switches against traffic
flooding caused by virus attacks. The switches also support 802.1X port based
authentication, allowing the network client to be authenticated through external
RADIUS servers. In addition, the Access Control List (ACL) feature enhances
network security and helps to protect the network by screening traffic from illegal
MAC or IP addresses. The DGS-1500 Series includes ARP Spoofing Prevention,
which protects from attacks on the Ethernet network that may allow an intruder
to sniff data frames, modify traffic, or bring traffic to a halt altogether by sending
fake ARP messages to the network. For added security, the DHCP Server
Screening feature screens rogue DHCP server packets from user ports to prevent
unauthorized IP assignment.
simplifies the initial setup of the Smart Switches. Switches within the same L2
network segment that are connected to the user’s PC are displayed on screen
for instant access. This allows extensive switch configuration and basic setup
of discovered devices including password changes and firmware upgrades.
The DGS-1500 Series also supports D-View 6.0 and a Compact Command Line
Interface (CLI). D-View 6.0 is a Network Management System that allows for
the central management of critical network characteristics such as availability,
reliability, resilience, and security. CLI management of the switches is possible via
Telnet. This makes it possible to adjust basic settings, passwords, configuration
files, and firmware with ease.
Limited Lifetime Warranty
D-Link offers a Limited Lifetime Warranty on the DGS-1500 Series SmartPro
switches to further its commitment to product quality and long-term
customer confidence.
