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, re, 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. Opening or removing covers that are marked with the triangular symbol with a lightning bolt may expose you to an electrical shock. Only a trained service technician should service components inside these compartments. If any of the following conditions occur, unplug the product from the electrical outlet and replace the part or contact your trained service provider: The power cable, extension cable, or plug is damaged. An object has fallen into the product. The product has been exposed to water. The product has been dropped or damaged. The product does not operate correctly when you follow the operating instructions. Keep your system away from radiators and heat sources. Also, do not block cooling vents. Do not spill food or liquids on your system components, and never operate the product in a wet environment. If the system gets wet, see the appropriate section in your troubleshooting guide or contact your trained service provider.
D-Link DGS-2208 User Manual 3
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.

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 Cable Diagnostic function operates only during the Switch boot up (when the Switch is rst powered on). The Cable Diagnostic rst scans the ve 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 ve ports, sequentially. The initial port scan takes about 10 seconds. If a cable fault is detected, it is indicated by the corresponding ports Speed LED glowing amber for 5 seconds, after the initial port scan. The Switch is then reset for normal operation. It takes about 2 seconds for the Switch to reset. The entire Cable Diagnostic process takes about 17 seconds from the time the Switch is booted. So, from the time power is rst applied to the Switch, about 17 seconds is required before the Switch will begin normal operation. NOTE: There is no display of cable faults detected by the Cable Diagnostic during the normal operation of the Switch, only when the Switch is booted up or power-cycled. NOTE: The Cable Diagnostic function does not support 10M/100M. If the port is connected to a 10M/100M device, see the Link LED to check if the cable is good or not.

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 specication section for information about the AC power input voltage. Since the DGS-2208 does not require a power button, plugging its power adapter into a power outlet will immediately power it on.

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 1.82 meters (6 feet) of the Switch. Visually inspect the power cord and see that it is fully secured to the AC power port. Make sure that there is adequate space for proper heat dissipation from and adequate ventilation around the Switch. Leave at least 10 cm (4 inches) of space at the front and rear of the Switch for ventilation. Install the Switch in a fairly cool and dry place for the acceptable temperature and humidity operating ranges. Install the Switch in a site free from strong electromagnetic eld generators (such as motors), vibration, dust, and direct exposure to sunlight. When installing the Switch on a level surface, attach the rubber feet to the bottom of the device. The rubber feet cushion the Switch, protect the casing from scratches, and prevent it from scratching other surfaces.

D-Link DGS-2208 User Manual 16
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.

Mounting on a wood wall

1. Drive the T3 x 15 L screws into the wood wall. 2. Hook the mounting holes of the switch back on the screws. (1) 3/4 inch minimum for wood wall (2) 3 inch minimum for cement wall.

Connecting the Switch

DGS-2208 to End Node
End nodes include PCs outtted 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. The LED over the port label indicates a port speed of either 10/100 Mbps or 1000Mbps. A blinking LED on the bottom indicates packet activity on that port.

Hub/Switch to DGS-2208

These connections can be accomplished in a number of ways using a standard Ethernet cable. A 10BASE-T hub or switch can be connected to the Switch via a twisted-pair Category 3, 4, 5, or 5e UTP/STP cable. A 100BASE-T hub or switch can be connected to the Switch via a twisted -pair Category 5 UTP/STP cable. A 1000BASE-T switch can be connected to the Switch via a twisted -pair Category 5e or better UTP/STP cable.
Connecting To Network Backbone or Server
Any of the ve Gigabit Ethernet ports are ideal for uplinking to a network backbone or network server.

Section 4 - Troubleshooting

Troubleshooting

1. Why cant 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. Another alternative is to contact your ISP and purchase extra IP addresses for each additional computer. 2. Does the DGS-2208 switch have an uplink port? The DGS-2208 has Auto-MDI ports which automatically sense the type of cable being used (e.g. Straight-through or Crossover) and adjust themselves accordingly to pass data over the network. 3. What is the maximum length of Category 3, 4 or 5 twisted pair cable that can be used between the DGS-2208 and other devices such as routers, switches, computers, etc.? The maximum length of Category 3, 4 or 5 twisted pair cable that can be used between computers and other devices on a network is 100 meters or about 328 feet. Keep in mind that this is a theoretical limit. Usually, you will want to keep the distance between devices well below the limit.

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 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.
