DGS-1224T/GEEOL EOS

Web Smart 24-Port 10/100/1000 + 2 combo SFP Switch

Description

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.
