48-Port 10/100/1000Base-T + 4 100/1000Base-T SFP SmartPro Switch
Description:
The DGS-1500 Series SmartPro Switch is the premier choice for SMBs that need powerful, flexible networking. The DGS-1500 Series features fanless models that stay cool and noiseless, as well as a PoE option that’s smart on energy consumption. All models include other smart power-saving technologies such as port standby and LED shutoff. Above all the DGS-1500 Series is secure, featuring SSHv02, SSL, ARP Spoofing Prevention, and more.
 
D-Link Green™ V3.0 Technology
The DGS-1500 Series implements D-Link Green™ 3.0 Technology, which includes a power saving mode, smart fan, increased heat dissipation, and cable length detection. The power-saving features include being able to schedule when to turn off LEDs and ports when not in use, and when to make the switch to enter hibernation mode. The switches can 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 toggling sleep mode on ports without a link. 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 features 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 workgroups and allows you to expand your network with D-Link’s management software. In static routing, IP routes are manually entered into a routing table. The DGS-1500 Series switches support static routing, which allows for communication between different user groups in different VLAN segments in a network. The switches can fully handle the inter-VLAN routing 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 2000Mbps 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 VoIP and video surveillance 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- 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 and an individual VLAN, these features guarantee the quality and security of 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 high 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 the Ethernet network from attacks 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 enables administrators to remotely control their network down to the port level. The SmartConsole easily allows customers to discover multiple D-Link Web 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 Compact Command Line Interface (CLI) through Telnet. 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.
