Do not push any objects into the openings of your system. Doing so can cause a re or an electric shock by shorting out interior components. Use the product only with approved equipment. Allow the product to cool before removing covers or touching internal components. Operate the product only from the type of external power source indicated on the electrical ratings label. If you are not sure of the type of power source required, consult your service provider or local power company. To help avoid damaging your system, be sure the voltage selection switch (if provided) on the power supply is set to match the power available at your location: 115 volts (V)/60 hertz (Hz) in most of North and South America and some Far Eastern countries such as South Korea and Taiwan. 100 V/50 Hz in eastern Japan and 100 V/60 Hz in western Japan. 230 V/50 Hz in most of Europe, the Middle East, and the Far East. Also be sure that attached devices are electrically rated to operate with the power available in your location. Use only approved power cable(s). If you have not been provided with a power cable for your system or for any AC-powered option intended for your system, purchase a power cable that is approved for use in your country. The power cable must be rated for the product and for the voltage and current marked on the products electrical ratings label. The voltage and current rating of the cable should be greater than the ratings marked on the product. To help prevent an electric shock, plug the system and peripheral power cables into properly grounded electrical outlets. These cables are equipped with three-prong plugs to help ensure proper grounding. Do not use adapter plugs or remove the grounding prong from a cable. If you must use an extension cable, use a 3-wire cable with properly grounded plugs.
D-Link DGS-2208 User Manual 4
Observe extension cable and power strip ratings. Make sure that the total ampere rating of all products plugged into the extension cable or power strip does not exceed 80 percent of the ampere ratings limit for the extension cable or power strip. To help protect your system from sudden, transient increases and decreases in electrical power, use a surge suppressor, line conditioner, or uninterruptible power supply (UPS). Position system cables and power cables carefully; route cables so that they cannot be stepped on or tripped over. Be sure that nothing rests on any cables. Do not modify power cables or plugs. Consult a licensed electrician or your power company for site modications. Always follow your local/national wiring rules. When connecting or disconnecting power to hot-pluggable power supplies, if offered with your system, observe the following guidelines: Install the power supply before connecting the power cable to the power supply. Unplug the power cable before removing the power supply. If the system has multiple sources of power, disconnect power from the system by unplugging all power cables from the power supplies. Move products with care; ensure that all casters and/or stabilizers are rmly connected to the system. Avoid sudden stops and uneven surfaces.
Protecting Against Electrostatic Discharge
Static electricity can harm delicate components inside your system. To prevent static damage, discharge static electricity from your body before you touch any of the electronic components, such as the microprocessor. You can do so by periodically touching an unpainted metal surface on the chassis. You can also take the following steps to prevent damage from electrostatic discharge (ESD): 1. When unpacking a static-sensitive component from its shipping carton, do not remove the component from the antistatic packing material until you are ready to install the component in your system. Just before unwrapping the antistatic packaging, be sure to discharge static electricity from your body. 2. When transporting a sensitive component, rst place it in an antistatic container or packaging. 3. Handle all sensitive components in a static-safe area. If possible, use antistatic oor pads, workbench pads, and an antistatic grounding strap.

Do not cover the ventilation holes on the sides of the Switch, and make sure there is adequate ventilation around it. Do not place heavy objects on the switch.
Fast Ethernet Technology The growing importance of LANs and the increasing complexity of desktop computing applications are fueling the need for high performance networks. 100BASE-TX (Fast Ethernet) provides a cost-effective and high-performance solution for small workgroups, SMBs (Small to Medium Businesses), and any network supporting bandwidth-intensive applications. Fast Ethernet technology operates at 10 times the speed of traditional Ethernet, offering maximum performance and enhanced capability for existing Ethernet-based networks. 100Mbps Fast Ethernet is a standard specied by the IEEE 802.3 LAN committee. It is an extension of the 10Mbps Ethernet standard with the ability to transmit and receive data at 100Mbps, while maintaining the CSMA/CD Ethernet protocol. Since the 100Mbps Fast Ethernet is compatible with all other 10Mbps Ethernet environments, it provides a straightforward upgrade and takes advantage of the existing investment in hardware, software, and personnel training. Gigabit Ethernet Technology Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same packet structure, format, and support for CSMA/CD protocol, full duplex, ow control, and management objects, but with a tenfold increase in theoretical throughput over 100Mbps Fast Ethernet and a one hundred-fold increase over 10Mbps Ethernet. Since it is compatible with all 10Mbps and 100Mbps Ethernet environments, Gigabit Ethernet provides a straightforward upgrade without wasting a companys existing investment in hardware, software, and trained personnel. The increased speed and extra bandwidth offered by Gigabit Ethernet are essential to coping with the network bottlenecks that frequently develop as computers and their busses get faster and more users use applications that generate more trafc. Upgrading key components, such as your backbone and servers to Gigabit Ethernet can greatly improve network response times as well as signicantly speed up the trafc between your subnetworks. Gigabit Ethernet enables fast optical ber connections to support video conferencing, complex imaging, and similar data-intensive applications. Likewise, since data transfers occur 10 times faster than Fast Ethernet, servers outtted with Gigabit Ethernet NICs are able to perform 10 times the number of operations in the same amount of time. In addition, the phenomenal bandwidth delivered by Gigabit Ethernet is the most cost-effective method to take advantage of today and tomorrows rapidly improving switching and routing internetworking technologies.
D-Link DGS-2208 User Manual 8
Switching Technology Switching is a cost-effective way of increasing the total network capacity available to users on a LAN. If an Ethernet network begins to display symptoms of congestion, low throughput, slow response times, and high rates of collision, installing a switch to a network can preserve much or all of the existing networks cabling and workstation interface card infrastructure, while still greatly enhancing the throughput for users. A switch is a viable solution even if demanding applications, such as multimedia production and video conferencing, are on the horizon. The most promising techniques, as well as the best return on investment, could well consist of installing the right mixture of Ethernet switches. A switch increases capacity and decreases network loading by dividing a local area network into different LAN segments. Dividing a LAN into multiple segments is one of the most common ways of increasing available bandwidth. If segmented correctly, most network trafc will remain within a single segment, enjoying the full-line speed bandwidth of that segment. Switches provide full-line speed and dedicated bandwidth for all connections. This is in contrast to hubs, which use the traditional shared networking topology, where the connected nodes contend for the same network bandwidth. When two switching nodes are communicating, they are connected with a dedicated channel between them, so there is no contention for network bandwidth with other nodes. As a result, the switch reduces considerably, the likelihood of trafc congestion. For Ethernet networks, a switch is an effective way of eliminating the problem of chaining hubs beyond the two-repeater limit. A switch can be used to split parts of the network into different collision domains, making it possible to expand your Ethernet network beyond the 205-meter network diameter limit for 100BASE-TX networks. Switches supporting both 10Mbps Ethernet and 100Mbps Fast Ethernet are also ideal for bridging between existing 10Mbps networks and newer 100Mbps networks. Switching LAN technology is a marked improvement over the previous generation of network hubs and bridges, which were characterized by higher latencies. Routers have also been used to segment local area networks, but the cost of a router, the setup and maintenance required, make routers relatively impractical. Today switches are an ideal solution to most kinds of local area network congestion problems.
802.1p Priority Tagging 802.1p places a tag in a frame to indicate the priority of the frame. A tag will represent a priority of 0-7 and an 802.1p compliant switch can read this tag and prioritize trafc accordingly. In 802.1p a port can receive frames with varying priority tags and classify them based on these tags. A VoIP phone that supports 802.1p can assign a priority to its VoIP trafc and when it enters the switch the switch can give it a higher priority so that voice trafc is always clear and jitter free. The DGS-2208 supports the 802.1p feature with 4 precongured priority queues. When a frame tagged with an 802.1p priority bit is received by the switch it places the frame into one of 4 queues prioritized according to its tag number. For example, trafc tagged with a priority bit of 7 will have a higher priority then trafc tagged with a priority bit of 6 and so forth. Jumbo Frame Support The DGS-2208 switch supports Jumbo Frames up to (9K) in size. Jumbo Frame support is designed to improve network throughput and signicantly reduce the CPU utilization of large le transfers such as multimedia les or large data les by enabling more efcient larger payloads per packet.
The DGS-2208 8-port 10/100/1000BASE-T Gigabit Ethernet Switch was designed for easy installation and high performance in an environment where trafc on the network and the number of users increase continuously.

half duplex A system that allows packets to be transmitted and received, but not at the same time. Contrast with full duplex. IP address Internet Protocol address. A unique identier for a device attached to a network using TCP/IP. The address is written as four octets separated with full-stops (periods), and is made up of a network section, an optional subnet section and a host section. IPX Internetwork Packet Exchange. A protocol allowing communication in a NetWare network. LAN Local Area Network. A network of connected computing resources (such as PCs, printers, servers) covering a relatively small geographic area (usually not larger than a oor or building). Characterized by high data rates and low error rates. latency The delay between the time a device receives a packet and the time the packet is forwarded out of the destination port. line speed See baud rate. main port The port in a resilient link that carries data trafc in normal operating conditions. MDI Medium Dependent Interface. An Ethernet port connection where the transmitter of one device is connected to the receiver of another device.
MDI-X Medium Dependent Interface Cross-over. An Ethernet port connection where the internal transmit and receive lines are crossed. MIB Management Information Base. Stores a devices management characteristics and parameters. MIBs are used by the Simple Network Management Protocol (SNMP) to contain attributes of their managed systems. The Switch contains its own internal MIB. multicast Single packets copied to a specic subset of network addresses. These addresses are specied in the destinationaddress eld of the packet. protocol A set of rules for communication between devices on a network. The rules dictate format, timing, sequencing, and error control. resilient link A pair of ports that can be congured so that one will take over data transmission should the other fail.

Check your IP address
After you install your new D-Link adapter, by default, the TCP/IP settings should be set to obtain an IP address from a DHCP server (i.e. wireless router) automatically. To verify your IP address, please follow the steps below. Click on Start > Run. In the run box type cmd and click OK. At the prompt, type ipcong and press Enter. This will display the IP address, subnet mask, and the default gateway of your adapter. If the address is 0.0.0.0, check your adapter installation, security settings, and the settings on your router. Some rewall software programs may block a DHCP request on newly installed adapters.
Statically Assign an IP address
If you are not using a DHCP capable gateway/router, or you need to assign a static IP address, please follow the steps below: Step 1 Windows XP - Click on Start > Control Panel > Network Connections. Windows 2000 - From the desktop, right-click My Network Places > Properties. Step 2 Right-click on the Local Area Connection which represents your D-Link network adapter and select Properties. Step 3 Highlight Internet Protocol (TCP/IP) and click Properties. Step 4 Click Use the following IP address and enter an IP address that is on the same subnet as your network or the LAN IP address on your router. Example: If the routers LAN IP address is 192.168.0.1, make your IP address 192.168.0.X where X is a number between 2 and 99. Make sure that the number you choose is not in use on the network. Set Default Gateway the same as the LAN IP address of your router (192.168.0.1). Set Primary DNS the same as the LAN IP address of your router (192.168.0.1). The Secondary DNS is not needed or you may enter a DNS server from your ISP. Step 5 Click OK twice to save your settings.
