User manual D-LINK DES-105

[. . . ] 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. [. . . ] The DES-105/108 can accommodate 10Mbps or 100Mbps devices, providing a flexible solution for existing (10Mbps) Ethernet workgroups. The DES-105/108 combines dynamic memory allocation with store-andforward switching to ensure that the buffer is effectively allocated for each port; and it controls the data flow between the transmit and receive nodes 4 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. Other key features include:  Supports Auto-Negotiation for 10/100Mbps and duplex mode  Supports Auto-MDI/MDIX for each port  Supports Full/Half duplex transfer mode for 10 and 100Mbps  Back pressure flow control for half duplex  Full wire speed reception and transmission  Store-and-Forward switching method  Supports 8K absolute MAC addresses  Supports 128KBytes RAM for data buffering  IEEE 802. 1p priority queues 5 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. Visually inspect the DC power jack and make sure that it is fully secured to the power adapter. Do not cover the ventilation holes on the sides of the Switch, and make sure there is adequate ventilation around it. 6 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. Blinking indicates the Switch is either sending or receiving data to the port. When the port LED glows in green, it indicates the port is running on 10M or 100M. auto MDI/MDI-X Ports: All ports support automatic MDI/MDI-X crossover detection. The AutoMDI/MDI-X function makes it simple to connect to the switch—just plug either a Crossover or Straight-Through CAT5 cable into any port. ρ®  7 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. [. . . ] 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. 11 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. [. . . ]
