Switch and guide you through the installation process. Conventions For simplicity, this documentation uses the term “Switch” (first letter upper case) to refer to the DES-1008D/ DSS-8+ Ethernet Switch, and “switch” (first letter lower case) to refer to other Ethernet switches.
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 high-performance solution for small workgroups, SMBs (Small to Medium Businesses), and any network supporting bandwidth-intensive applications.

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 traffic will remain within a single segment, enjoying the full- line speed bandwidth of that segment.
200Mbps, any one of its eight ports may be used to cascade to an additional switch to open a Full-Duplex Fast Ethernet pipe. The DES-1008D/ DSS-8+ is the perfect choice for a department or office planning to upgrade to Fast Ethernet. The DES-1008D/ DSS- 8+ can accommodate 10Mbps or 100Mbps devices, providing a flexible solution for existing (10Mbps) Ethernet workgroups.

complete frame checking and error frame filtering, this scheme prevents error packages from transmitting among segments. Auto-MDI/MDI-X. Detects the type of cable you are using, Crossover or Straight-Through, and automatically adjusts per port, allowing you to also use any port as an uplink port—the choice is yours.
If any item is missing or damaged, please contact your local reseller for a replacement. Setup The setup of the DES-1008D/ DSS-8+ can be performed using the following steps: The power outlet should be within 1.82 meters (6 feet) of the Switch.
DENTIFYING XTERNAL OMPONENTS Front Panel The figure below shows the front panel of the DES-1008D/ DSS-8+. Front Panel LED Indicators LED Indicators Power Indicator This green indicator light is on when the DES-1008D/ DSS-8+ is receiving power; otherwise, it is off.
Power is supplied through an external DC power adapter. Check the technical specification section for information about the DC power input voltage. Since the DES-1008D/ DSS-8+ does not include a power button, plugging its power adapter into a power outlet will immediately power it on.
Straight-Through or Crossover cable. For 100Mbps operation a Category 5 cable must be used. The connection is accomplished from any port of the hub to any port of the DES-1008D/ DSS-8+. DES-1008D/ DSS-8+ to other devices The DES-1008D/ DSS-8+ can be connected to another switch or other devices (routers, bridges, etc.) via a two-pair Category 3, 4, 5...
Port Speed & Duplex Mode After plugging the selected cable to a specific port, the system uses auto-negotiation 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 auto-negotiation disabled, an auto-sensing process is initiated to select the speed and half-duplex mode is selected.
OUNTING THE WITCH ON A The DES-1008D/ DSS-8+ 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.
