A BOUT T HIS G UIDE Congratulations on your purchase of the D-Link DES-105/108. This device integrates 100Mbps Fast Ethernet and 10Mbps Ethernet network capabilities in one high-performance, easy-to-use solution. Purpose This manual will familiarize you with the DES-105/108 and guide you through the installation process.
I NTRODUCTION 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-T (Fast Ethernet) provides a cost-effective and highperformance solution for small workgroups, SMBs (Small to Medium Businesses), and any network supporting bandwidth-intensive applications.
multiple segments is one of the most common ways of increasing available bandwidth. If segmented correctly, most network traffic 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.
Features The DES-105/108 is a high performance switch designed specifically for environments where traffic on the network and the number of users increase continuously. DES-105/108 implements D-Link’s Green Technology special powersaving features under speed at 100Mbps that link status and adjust power usage accordingly. Further, D-Link Green implements the newly ratified IEEE 802.
to guarantee against possible packet loss. The DES-105/108 is an unmanaged 10/100Mbps Fast Ethernet switch that offers solutions for the accelerating bandwidth needs of small Ethernet workgroups.
U NPACKING AND S ETUP Unpacking Open the box and carefully unpack it. The box should contain the following items: One DES-105/108: 5/8-Port 10/100Mbps Ethernet Switch One External Power Adapter Wall Mount Kit Quick Installation Guide If any item is missing or damaged, please contact your local reseller for a replacement. Setup The setup of the DES-105/108 can be performed using the following steps: The power outlet should be within 1.82 meters (6 feet) of the Switch.
I DENTIFYING E XTERNAL C OMPONENTS Front Panel The figure below shows the front panel of the DES-105/108. DES-105/108 10/100Mbps Fast Ethernet Switch Power/LED: This green indicator light is on when the DES-105/108 is receiving power; otherwise, it is off. 100Mbps Link/Activity, 10Mbps Link/Activity Indicator 100 Link/Act (green): There are two LED indicators for each Ethernet port. The port LEDs indicate a network link through the corresponding port.
Rear Panel DES-105/108 10/100Mbps Fast Ethernet Switch Power Jack: Power is supplied through an external power adapter. Check the technical specification section for information about the power input voltage. Since the DES-105/108 does not require a power button, plugging its power adapter into a power outlet will immediately power it on. Kensington Security Slot DES-105/108 has been giving customers the best option for physical security through a Kensington Security Slot in the rear panel.
proper grounding facilities. ‧A screwdriver (not included in the accessory kit) The following steps let you connect the switch to a protective ground: Step 1: Verify if the system power is off. Step 2: Use the ground cable to place the #8 terminal lug ring on top of the ground-screw opening, as seen in the figure below. Step 3: Insert the ground screw into the ground-screw opening. Step 4: Using a screwdriver, tighten the ground screw to secure the ground cable to the switch.
CONNECTING THE SWITCH PC to DES-105/108 A computer can be connected to the DES-105/108 via a two-pair Category 3, 4, 5 UTP/STP Straight-Through or Crossover cable. A computer equipped with a RJ-45 10/100Mbps port can be connected to any of the five DES-105/108 ports. The LED indicators for the PC connection depend on the capability of the computer’s Ethernet card.
Port Speed & Duplex Mode After plugging the selected cable to a specific port, the system uses autonegotiation to determine the transmission mode, auto-detecting the network speed (10Mbps or 100Mbps) for any new twisted-pair connection. If the attached device does not support auto-negotiation or has autonegotiation disabled, an auto-sensing process is initiated to select the speed and half-duplex mode is selected.
M OUNTING THE S WITCH ON A WALL The DES-105/108 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: A.) Mounting on 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.
