Section 1 - Safety Instructions Safety Instructions Use the following safety guidelines to ensure your own personal safety and to help protect your system from potential damage. Safety Cautions To reduce the risk of bodily injury, electrical shock, fire, and damage to the equipment, observe the following precautions. Observe and follow service markings. Do not service any product except as explained in your system documentation.
Section 1 - Safety Instructions • Do not push any objects into the openings of your system. Doing so can cause a fire 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.
Section 1 - Safety Instructions • 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).
Section 1 - Safety Instructions 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.
Section 2 - Product Overview Product PackageOverview Contents • D-Link DGS-2208 8-port Switch • Manual and Warranty on CD • Four (4) Rubber Feet • Wall Mount Kit • Power Adapter Setup The setup of the DGS-2208 can be performed using the following steps: • The power outlet should be within 1.82 meters (6 feet) of the Switch. • Visually inspect the DC power jack and make sure that it is fully secured to the power adapter.
Section 2 - Product Overview Introduction 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.
Section 2 - Product Overview 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 network’s cabling and workstation interface card infrastructure, while still greatly enhancing the throughput for users.
Section 2 - Product Overview 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 traffic 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.
Section 2 - Product Overview Features The DGS-2208 8-port 10/100/1000BASE-T Gigabit Ethernet Switch was designed for easy installation and high performance in an environment where traffic on the network and the number of users increase continuously.
Section 2 - Product Overview Hardware Overview Front Panel (LEDs) The LED indicators of the Switch include Power, 100/1000Mbps, and Link/Act. The following shows the LED indicators for the Switch along with an explanation of each indicator. LED Indicators: Comprehensive LED indicators display the conditions of the Switch and status of the network. A description of these LED indicators follows (see LED Indicators). The LED indicators of the Switch include Power, Link/Act, 1000Mbps, and 100Mbps.
Section 2 - Product Overview Power Indicator This green indicator illuminates when the Switch is receiving power. Link/Act This green indicator illuminates steadily when a port is connected to a station successfully and has a good link. The indicator will blink to indicate that a port is transmitting or receiving data on the network. Speed − 1000Mbps/Green; 100Mbps/Amber; 10Mbps/Off This indicator is amber-colored when the port is connected to a 100Mbps Fast Ethernet station.
Section 2 - Product Overview The Cable Diagnostic function operates only during the Switch boot up (when the Switch is first powered on). The Cable Diagnostic first scans the five Ethernet ports to determine if the Ethernet cable is in good working order. This process is indicated by the Speed LED blinking green for each of the five ports, sequentially. The initial port scan takes about 10 seconds.
Section 2 - Product Overview Rear Panel (Connections) Auto MDI/MDI-X Ports: Eight (8) Gigabit Ethernet, Auto-Negotiating ports (10/100/1000Mbps) Comprehensive LED indicators display the conditions of the Switch and status of the network. DC Power Jack: Power is supplied through an external AC power adapter. Check the technical specification section for information about the AC power input voltage.
Section 3 - Installation Installation This section will explain how to connect Ethernet devices to your new D-Link switch and how to mount the switch. Before You Connect to the Network The site where you install the Switch may greatly affect its performance. Please follow these guidelines for setting up the Switch. • Install the Switch on a sturdy, level surface that can support at least 3 kg (6.6 lbs.) of weight. Do not place heavy objects on the Switch. • The power outlet should be within 1.
Section 3 - Installation Mounting the Switch on the Wall The DGS-2208 can also be mounted on a wall. Two mounting slots are provided on the bottom of the switch for this purpose. Please make sure that the front panel is exposed in order to view the LEDs. Please refer to the illustration below: Mounting on a cement wall 1. Mount the Nylon screw anchors into a cement wall. 2. Drive the T3 x 15L screws into the Nylon screw anchors. 3. Hook the mounting holes of the switch back on the screws.
Section 3 - Installation Connecting the Switch DGS-2208 to End Node End nodes include PCs outfitted with a 10, 100, or 1000 Mbps RJ-45 Ethernet Network Interface Card (NIC) and most routers. An end node can be connected to the Switch via a twisted-pair Category 3, 4, 5, or 5e UTP/STP cable. The end node can be connected to any of the ports of the Switch. The Link/Act LEDs for each UTP port light green when the link is valid.
Section 4 - Troubleshooting Troubleshooting 1. Why can´t I share my Internet connection to multiple computers when using my D-Link DGS-2208 switch? If you are connecting directly to a Cable or DSL modem, you will need a router to “share” your Internet connection or a computer using ICS (Internet Connection Sharing) or Proxy. Switches and hubs do not allow you to share a single IP address to multiple computers.

Appendix A - Networking Basics Networking Basics 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 ipconfig and press Enter. This will display the IP address, subnet mask, and the default gateway of your adapter.
Appendix A - Networking Basics 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.
