connecting end node or hub or switch

    1. place the switch on a smooth surface or fasten the mounting brackets with the provided screws in a standard 19" rack

    2. connect the dc jack of ac adapter to the dc inlet socket of switch and the other end into the local power source outlet

    3. connect hub or pc to one port of the switch using category 3/4/5 utp/stp cabling

    4. connect another hub or pc to the other port of 8/16/24-port giga switch by following the same process as described in step3.

    1 cable distance for switch

    the cable distance between ethernet switch and hub/pc should not exceed 100 meter, fiber cable distance shall not exceed 220 meter.

    2 make sure the wiring is correct

    it can be used category 3/4/5 cable in 10 mbps operation. to reliably operate your network at 100mbps, you must use an unshielded twisted-pair (utp) category 5 cable, or better data grade cabling. while a category 3 or 4 cable may initially seem to work, it will soon cause data loss. or 1000base-sx multi-mode 62.5/125μm fiber optic cable for fiber connector application.

    all kinds of hub/pc can connect to 8/16/24 port 10/100mbps switch by using straight-through wires. the 8/16/24 port 10/100mbps switch provides one additional rj-45 connector converted from port no.4 (8port switch), no.12(16port switch), or no.20(24port switch) for "up-link" function. 1000base-tx is auto-mdi/ mdi-x can be used on straight-through or crossover cable.

    connecting to network backbone or server

    connect to the gigabit ethernet ports with category 5 copper cable or fiber optic cable for uplinking to a network backbone or network server.

    these ports operate at 1000mbps in full-duplex mode. a valid connection is indicated when the link led is light.

    the following sections describe the function of leds on the front panel

    cpu led

    color: green

    label: smart

    function: the led light up steadily means cpu installed for smart function

    1. 10/100m

    full/ half duplex and collision led

    color: green/ yellow (green for 100mbps, yellow for 10mbps)

    label: fdx/ col

    function: a "collision" in ethernet, is when two end nodes transmit at the same time. the indicator flash yellow color up whenever there is a collision between a directly attached end node and any other node.

    if led light remove steadily, it means in full-duplex.

    link and activity

    color: green/ yellow (green for 100mbps, yellow for 10mbps)

    label: link/ act

    function: each rj45 station port on the hub is assigned one led for monitoring port "good link" and data traffic. the led is normally off.

    after the power on operation, led will light green color steadily to show "good link" when port is been connected with 100mbps.

    the led will flash yellow color rapidly to show data passing in and out the port with 10mbps.

    2. 1000mpbs

    link/ speed led

    color: green

    label: l10/ l100/ l1000

    function: the led light up steadily to indicate the transmitting speed

    l10: light up steadily to indicate link up at speed 10m

    l100: light up steadily to indicate link up at speed 100m

    l1000: light up steadily to indicate link up speed 1g

    full/ half duplex and collision led

    color: green

    label: fdx/ col

    function: the indicator led flash up whenever there is a collision between a directly attached end node and any other node, and light up steadily for full-duplex mode.

    tx activity

    color: green

    label: link/ act

    function: each rj45 station port on the hub is assigned one led for transmitting the data.
