Product Description

Overview

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 environments.

Power over Ethernet

The DGS-1500-28P’s 10/100/1000 Mbps ports are PoE-enabled for powering devices such as IP cameras, VoIP phones and wireless access points. Compliant with 802.af and 802.3at, 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 and increasing security by powering off devices that should not be in use during non-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 quality.

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 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 video packets take precedence over other packets. In addition, with Bandwidth Control, network administrators can reserve bandwidth for important functions that require more bandwidth or might require higher priority.

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.

Versatile Management

The DGS-1500 series provides a SmartConsole utility and a web-based management interface that enable administrators to remotely control their network down to the port level. The SmartConsole easily allows customers to 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 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.
