D-Link DGS-108 Unmanaged Gigabit Ethernet Switch Safety Instructions Use the following safety guidelines to ensure your own personal safety and to help protect your system from potential damage. Throughout this safety section, the caution icon ( ) is used to indicate cautions and precautions that you need to review and follow. 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.
D-Link DGS-108 Unmanaged Gigabit Ethernet Switch Safety Instructions (continued) 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 product's electrical ratings label.
D-Link DGS-108 Unmanaged Gigabit Ethernet Switch Safety Instructions (continued) Always load the rack from the bottom up, and load the heaviest item in the rack first. Make sure that the rack is level and stable before extending a component from the rack. Use caution when pressing the component rail release latches and sliding a component into or out of a rack; the slide rails can pinch your fingers.
D-Link DGS-108 Unmanaged Gigabit Ethernet Switch SECTION 1 Introduction Ethernet Technology Switch Description Features Ports Front-Panel Components Ethernet Technology Fast Ethernet Technology The growing importance of LANs and the increasing complexity of desktop computing applications are fueling the need for high performance networks. A number of high-speed LAN technologies are proposed to provide greater bandwidth and improve client/server response times.
D-Link DGS-108 Unmanaged Gigabit Ethernet Switch with any other segments (ports). This allows the total network capacity to be multiplied, while still maintaining the same network cabling and adapter cards. For Fast Ethernet or Gigabit Ethernet networks, a switch is an effective way of eliminating problems of chaining hubs beyond the “two-repeater limit.
D-Link DGS-108 Unmanaged Gigabit Ethernet Switch Front-Panel Components The front panel of the Switch consists of LED indicators, eight (10/100/1000 Mbps) Ethernet ports. Figure 1-1. Front Panel View of the Switch Comprehensive LED indicators display the status of the Switch and the network. LED Indicators 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. Figure 1-2.
D-Link DGS-108 Unmanaged Gigabit Ethernet Switch The Cable Diagnostic function operates only during the Switch boot up (when the Switch is first powered on). The Cable Diagnostic first scans the eight 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 eight ports, sequentially. The initial port scan takes about 10 seconds.
D-Link DGS-108 Unmanaged Gigabit Ethernet Switch Rear Panel Description 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. Figure 1-3. Rear panel view of the Switch 10/100/1000BASE-T Ports: Eight Gigabit Ethernet, Auto-Negotiating ports (10/100/1000Mbps) Comprehensive LED indicators display the conditions of the Switch and status of the network.
D-Link DGS-108 Unmanaged Gigabit Ethernet Switch SECTION 2 Installation Package Contents Before You Connect to the Network Installing the Switch Power On Package Contents Open the shipping carton of the Switch and carefully unpack its contents.
D-Link DGS-108 Unmanaged Gigabit Ethernet Switch Mounting the Switch on a Wall The DGS-108 can be mounted on a wall. Two mounting slots are provided on the bottom of the Switch for this purpose. Make sure that the front panel is exposed in order to view the LEDs. Refer to the illustration below: A.) Cement wall 1. 2. 3. Mount the nylon screw anchors into a cement wall. Drive the T3 x 15L screws into the nylon screw anchors. Hook the mounting holes at the back of the switch onto the screws.
D-Link DGS-108 Unmanaged Gigabit Ethernet Switch Attaching the Rubber Feet Use the rubber feet provided. Position and apply the rubber feet to the underside of the DGS-108 Switch. Figure 2- 2. Attaching the Rubber Feet Provide for Adequate Ventilation CAUTION: Do not place any device on top of Switch, or place the Switch on top of any device or object that will block the free flow of air through the ventilation slots on the sides, top, and bottom of the Switch’s case.
D-Link DGS-108 Unmanaged Gigabit Ethernet Switch Section 3 Connecting The Switch Switch To End Node Switch To Hub or Switch Connecting To a Server NOTE: All eight high-performance NWay Ethernet ports can support both MDIII and MDI-X connections. Switch To End Node End nodes include PCs outfitted with a 10, 100, or 1000 Mbps RJ-45 Ethernet/Fast 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.
D-Link DGS-108 Unmanaged Gigabit Ethernet Switch A 1000BASE-T switch can be connected to the Switch via a twisted -pair Category 5e or better UTP/STP cable. Figure 3-2. Switch connected to a port on a hub or switch using either a straight or crossover cable– any standard Ethernet cable is fine Connecting To Network Backbone or Server Any of the eight Gigabit Ethernet ports are ideal for uplinking to a network backbone or network server. Figure 3-3.
