Bedienungsanleitung D-LINK DGS-1224TP BROCHURE 1

[. . . ] Power over Ethernet easily allows you to install and power wireless access points, network cameras, VoIP phones and other network equipment for simplified 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. [. . . ] 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. Traffic Prioritization 802. 1Q VLAN tagging prioritizes traffic, 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 filters screen, for easy access to the network. They support 802. 1X port-based authentication, allowing the network to be configured with external RADIUS servers. [. . . ] The GUI also includes a wizard that allows you to pre-configure 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. 02 DGS-1216T, DGS-1224T, DGS-1224TP & DGS-1248T 16/24/48-Port Gigabit Web Smart Switches Technical Specifications General Port Standards & Functions IEEE 802. 3 10BASE-T Ethernet (twisted-pair copper) IEEE 802. 3u 100BASE-TX Fast Ethernet (twisted-pair copper) IEEE 802. 3ab 1000BASE-T Gigabit Ethernet (twisted- pair copper) IEEE 802. 3z Gigabit Ethernet (fiber) ANSI/IEEE 802. 3 NWay Auto-Negotiation IEEE 802. 3x Flow Control 802. 3af Power over Ethernet (for DGS-1224TP only) DGS-1216T: 16 10/100/1000BASE-T ports, 2 combo SFP slots DGS-1224T: 24 10/100/1000BASE-T ports, 2 combo SFP slots DGS-1224TP: 24 10/100/1000BASE-T PoE ports, 4 combo SFP slots DGS-1248T: 48 10/100/1000BASE-T ports, 4 combo SFP slots * Use of SFP will disable their corresponding 10/100/1000BASE-T connections Number of Ports SFP Modules Optional SFP Transceivers: DEM-310GT 1000BASE-LX, Single-mode, 10km DEM-311GT 1000BASE-SX, Multi-mode, 500m DEM-312GT2 1000BASE-SX, Multi-mode, 2km DEM-314GT 1000BASE-LX, Single-mode, 50km DEM-315GT 1000BASE-LX, Single-mode, 80km Optional WDM Transceivers: DEM-330T (1000BASE-LX, wavelength Tx: 1550nm, Rx: 1310nm, Single-mode, 10km) DEM-330R (1000BASE-LX, wavelength Tx: 1310nm, Rx: 1550nm, Single-mode, 10km) DEM-331T (1000BASE-LX, wavelength Tx: 1550nm, Rx: 1310nm, Single-mode, 40km) DEM-331R (1000BASE-LX, wavelength Tx: 1310nm, Rx: 1550nm, Single-mode, 40km) Ethernet: 10Mbps (half duplex) 20Mbps (full duplex) Fast Ethernet: 100Mbps (half duplex) 200Mbps (full duplex) Gigabit Ethernet: 2000Mbps (full duplex) Star UTP Cat.
