D-Link DGS-1500-28 28-port Gigabit SmartPro Switch - switch - 28 ports - managed - rack-mountable

D-Link's DGS-1500 SmartProfamily switches are designed for small/medium businesses who require functions like L3 Static Routing and Single IP Management (Virtual Stacking) without upgrading to a managed switch. The family 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 provide the added benefit of significant power savings. Additionally, the DGS-1500-28P's 10/100/1000 Mbps ports are PoE-enabled, offering ease-of-use and green features like Time-based PoE, which shuts the power off at a predetermined times. Compliant with 802.3af and 802.3at, these switches are capable of feeding power to devices of up to 30 Watts. Management options for the switches include SNMP, Web Management, SmartConsole Utility, and Compact CLI. The family also supports ACL filtering and D-Link's Safeguard Engine. The DGS-1500 family uses Auto Voice VLAN, ensuring higher priority for voice traffic. The DGS-1500-20 and DGS-1500-28 are both fanless which allows them to emit less heat and noise than a standard switch, making them suitable for office environments. The DGS-1500-28P and DGS-1500-52 both feature smart fans that use a thermal sensor that can detect temperature change, the smart fans can react accordingly by utilizing different fan speeds for different temperatures. The Smart Fan feature enables the built-in fans to automatically turn on at a certain temperature, providing continuous, reliable and eco-friendly operation of the switch.

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-1500 SmartPro family implements D-Link Green Technology, which includes a power saving mode, smart fan, reduced 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 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 up to 20 meters. The switches can also support power-saving by link status, which drastically reduces power consumption by automatically toggling ports without a link to sleep mode.

The DGS-1500 SmartPro family features advanced features such as Virtual Stacking and Layer 3 features like 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.

These switches are equipped with a complete line-up 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, which is used to detect loops created by a specific port or VLAN and will automatically shut down the affected port or VLAN. and Cable Diagnostics which is designed to rapidly discover the type of error on cables and determine the cable quality.

The DGS-1500 SmartPro family 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 SmartPro 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.
