Glossary – Lists definitions for terms and acronyms used in this document. Intended Readers The DGS-108 Manual contains information for setup and management and of the DGS-108 Switch. This manual is intended for network managers familiar with network management concepts and terminology.
• 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.

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.
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.
The switch acts as a high-speed selective bridge between the individual segments. Traffic that needs to go from one segment to another (from one port to another) is automatically forwarded by the switch, without interfering...
Switch Description The DGS-108 Switch is equipped with eight ports providing dedicated 10, 100, or 1000 Mbps bandwidth. These ports can be used for connecting PCs, printers, servers, routers, Switches, hubs, and other network devices. The eight multi-speed ports use standard twisted pair cabling and are ideal for segmenting networks into small, connected subnets.
10Mbps Ethernet station. Cable Diagnostic − LED Indications When the Switch is booted up (when the Switch is first powered on), the Cable Diagnostic function is initialized and run. The Cable Diagnostic function will detect three common faults in an Ethernet...

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.
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.
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. •...
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...
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: 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.
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. The end node can be connected to any of the ports of the 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.
– A port that does not learn device addresses, and that receives all frames with an unknown address. Backbone ports are normally used to connect the Switch to the backbone of your network. Note that backbone ports were formerly known as designated downlink ports.

– The port in a resilient link that will take over data transmission if the main port in the link fails. switch – A device that filters, forwards, and floods packets based on the packet’s destination address. The Switch learns the addresses associated with each switch port and builds tables based on this information to be used for the switching decision.
