D-Link’s latest generation Gigabit Web Smart Switch series is designed mainly to enhance the performance and security of small business networks. With four models to choose from, the DGS-1216T/1224T/1224TP/1248T brings Gigabit speeds to support bandwidth-intensive applications and further expand your network of switches. Enhanced  features  include  Gigabit  uplink  combo ports,  Power  over  Ethernet 1,  QoS  and  versatile management  functions.  Power  over  Ethernet easily  allows  you  to  install  and  power  wireless access  points,  network  cameras,  VoIP  phones and  other  network  equipment  for  simplif ed  and reduced deployment costs. Total PoE power budget on  24  10/100/1000  ports  for  the  DGS-1224TP  is  180watts.  Therefore, the maximum output power per PoE port is up to 15.4W on 11 ports or 7.5W on 24 ports simultaneously.

The switches are housed in a new style 19”rack-mount metal case with an easy-to-view front panel and diagnostic LEDs and feature an innovative fanless design2.  A user-friendly web-based management is supported for easy configuration and f exibility for different network requirements.

D-Link Green Technology
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-1216T/1224T/1224TP/1248T web  smart  switches  implement  the  D-Link  Green Technology, which  include Green  features such as the power saving mode, reduced power consumption and  reduced heat dissipation. The switches adopt the latest silicon technology, which helps lower your power consumption usage. The power saving feature automatically powers down ports that have no links or link partners.

 Protecting The Environment For A Better Tomorrow
The  incorporation  of  the  D-Link  Green  technology into  these  switches  re-emphasizes D-Link’s strong commitment  to protecting  the environment, leading  the  development  of  eco-friendly  products. These switches comply with RoHS (Restriction of Hazardous Substances) and WEEE (Waste Electrical and Electronic Equipment) directives. RoHS directives  restrict  the  use  of  specify  hazardous materials during  the manufacture of electrical and electronic goods, while WEEE applies standards for proper  disposal  and  recyclable  packaging  to  help reduce wastage.

Seamless Integration
The  switches  offer  Gigabit  copper  ports  that  are capable of connecting to your existing Cat.5 twisted-pair cables. This eliminates  the need of a complex re-conf guration process. Each switch model of the Gigabit series provides two or four combo SFP slots to  form  a multi-level  network  structure  consisting of a high-speed backbone and centralized servers. In  addition,  all  the  ports  support  auto-negotiation and  MDI/MDIX  crossover  function.  So  do  away with  cross  over  cables  or  uplink  ports  and  bring inexpensive Gigabit connection to your desktop.

Extensive Layer 2 Features
The  switches  offer  superior  performance  and availability through features such as Jumbo Frames, IGMP Snooping, Port Mirroring, Spanning Tree and Port Trunking. IEEE 802.3x Flow Control allows your servers  to  directly  connect  to  the  switch  for  fast, reliable  data  transfer.  The  Gigabit  ports  provide dedicated bandwidths for your desktops running at 2000Mbps  full  duplex, with minimum  data  transfer loss.

Traff c Prioritization
802.1Q  VLAN  tagging  prioritizes  traff c,  enhances network  security  and  performance  while  802.1p enables you to run bandwidth-sensitive applications such as streaming multimedia and VoIP in network. These functions allow switches to work seamlessly in the network.

Cable Diagnostics
Gigabit  networks  use  8-wire  CAT  5  RJ-45  cables. However,  networks  in  older  buildings  could  still be  using  4-wire  CAT  3/5  RJ-45  cables.  The  Cable Diagnostics  function  assists  you  to  effectively detect  the  RJ-45  cable  condition  while  migrating from an existing network to a Gigabit-capable one, and minimizing service calls during migration. Other cable-related problems are, an RJ-45 cable with an open circuit  (a  lack of continuity between  the pins at each end of an Ethernet cable or a disconnected cable)  or  a  short  circuit  between  two  or  more conductors.

Network Security
The switches provide MAC address f lters screen, for easy access to the network. They support 802.1X port-based  authentication,  allowing  the  network to  be  conf gured  with  external  RADIUS  servers. Enhance your network security with the Asymmetric VLAN feature. With this feature, you can segregate ports  into different  virtual  LAN groups  to enhance security  and  prevent  data  leaks.  This  feature  also increases the eff ciency of sharing resources such as servers or gateway devices.

D-Link  Safeguard  Engine  identif es  and  prioritizes “CPU  interested”  packets  to  prevent  malicious traff c  from  interrupting normal network f ows and protects switch operation.

Versatile Management
The switches’ web-based SmartConsole Utility is as easy to use as surf ng the web. The utility  includes useful  features  that  automatically  discover  and display  all  web  smart  switches  on  the  same  L2
network segment connected to a local PC. The web-based GUI allows for easy access to a switch from anywhere  without having to remember IP addresses or  subnets.  The  GUI  also  includes  a  wizard  that allows you to pre-conf gure basic functions such as passwords, system information and SNMP settings. Users can also use the built-in MIB browser to poll the switches for  information about their status and send  trap messages of abnormal events. The MIB browser allows users to integrate the switches with the third-party devices for management in an SNMP environment.
