    Troubleshooting


    Distance Limitations. The distance from a node (PC, Print Server, etc) to a hub or switch using RJ-45 cabling running at 10Mbps or 100Mbps is maximum of 100 meters (328 feet). The maximum cable (RJ-45) distance between two 100Mbps or 10/100 hubs without a switch is 5 meters (16 feet). Only two 100Mbps or 10/100 hubs can be cascaded together, a switch is required for more than two hubs. The maximum cable (RJ-45) distance from any node, hub or switch to a switch is 100 meters (328 feet). The maximum cable (RJ-45) distance from any 10Mbps node, 10Mbps hub, or a 10/100 hub or switch to a 10Mbps hub is 100 meters (328 feet).

  • Coiled cables. Verify that the network cabling isn't coiled or twisted up. Coiled cabling can create electromagnetic fields that may disrupt data transfers between nodes.

  • Avoid interference. Network cabling can be run under floors, around offices dividers, or over dropped ceilings. When planning your wiring layout, try to keep cables away from power outlets, florescent lighting fixtures, uninterruptable power supplies, and other sources of strong electromagnetic interference.

  • PC-to-Hub connections. When connecting a PC to a hub, make sure that your RJ-45 cabling is straight-through. Pins 1, 2, 3, and 6 at the PC should line up pin-for-pin at the hub. And if the cabling is used with Fast Ethernet network segment, make sure it is Category 5 for best results. For more information about cabling, see our cabling guide.

  • Hub-to-Hub connections. When connecting two hubs together with RJ-45 cabling, be sure that the cabling is crossed over (if neither hub has an Uplink Port that can be utilized). Pins 1, 2, 3 and 6 at hub "A" should line up with pins 3, 6, 1, and 2 at hub "B", respectively. For more information about cabling, see our cabling guide.

    10BASET Network Hub Hardware Setup


    Connecting Computers to the Hub

    The hub can be connected to 10Mbps computers, file servers, networkable printers, or other hardware. When powered up, each of the hub’s 10BaseT ports will automatically detect whether a computer is connected to the port.

    Here are some important points to remember.

    1. Connect each of your computers, file servers or other network computers to the hub one by one.

    2. Each computer should be connected to the hub with a straight-through, RJ-45, Category 5 cable. Each cable should be less than 100 meters (328 feet), in length. Ready-to-use network cables of various lengths can be purchased at most computer stores. See page 11 for cabling specifications.

    3. When connecting a computer to a hub, either the computer or the hub must be powered OFF. If both the computer and the hub are turned on while the connection is completed, the network will act erratically and you must reset the hub (see page 10).

    4. If the Uplink port is in use (connected to another hub, etc.), the port next to the Uplink port must remain empty and unused. As in most hubs, the Hub’s Uplink port and the port adjacent to it are joined together inside the hub, and one cannot be used while the other is in use. If you have an 8-port hub, for example, port 8 cannot be used if the Uplink port is in use, and vice-versa. See the next page for special considerations about uplinking.


    Connecting the Hub to Other Hubs or Switches

    Like most hubs, the Ethernet 10Mbps hubs can be uplinked to 10Mbps, 10/100 switches or broadband Internet devices. The back of each hub has an Uplink port for this purpose.

    If you are connecting the hub to another Ethernet hub or a 10/100 switch, remember that Ethernet rules only allow two hubs to be connected together, or uplinked, within a single network.

    To uplink the hub, simply connect a regular straight-through Category 5 cable from the hub’s Uplink port to any regular network port on the hub or switch being uplinked. The hub will automatically sense a detection and the uplink LED will turn on.

    Remember that while the Uplink port is in use, the port adjacent to it must remain open, and should not be connected to any cable or computer. See page 4 for important limitations when connecting hubs.

    Note: In order to connect to a 100Mbps hub or other Fast Ethernet hardware, a 10/100 hub or switch is required.


    Connecting to a Cable Modem or DSL Modem

    If you have a cable modem or DSL modem in your home or office, and you want to share it across your network, it’s very easy to do with the 5-Port or 8-Port Ethernet Hub.

    Most broadband devices translate your Internet connection into a 10BaseT Ethernet connection. If you have a cable modem or DSL modem that uses a 10BaseT connection, simply attach your device directly to the Uplink port on your Network Everywhere hub. Use a regular straight-through cable. In some cases, you may have to connect to a regular port on the hub using a cross-over cable. If a connection is made, the Link LED that corresponds to the port on the hub to which the broadband device is connected will light up.

    If you have an internal cable or DSL modem, or if your broadband device does not use a 10BaseT Ethernet connection, talk to your service provider about switching to a sharable device with a 10BaseT connection.

    In order to set up your broadband service so that your entire network can share the connection, talk to your service provider. They should be able to help you configure your networked PCs for a small fee.

    Powering On the Hub

    The hub comes with an AC to DC power adapter. Plug the power adapter’s plug into the hub’s power jack on the back of the unit. Plug the other end of the adapter into a standard AC electrical outlet. The hub will put itself through a series of diagnostic tests -- which shouldn’t take more than just a few seconds -- then begin scanning the ports for live computers. The installation is complete.


    Resetting the Hub

    To reset the hub, turn the unit off for at least three seconds and then turn it back on.

    Note: If you power cycle the hub for too long, you may lose some connections.

    10/100 Network Hub Hardware Setup


    Connecting Computers to the 10/100 Hub

    The hub can be connected to either 10Mbps or 100Mbps PCs, file servers, networkable printers, or other hardware. When powered up, each of the hub’s 10/100 ports will automatically adjust to the proper speed, as determined by the speed of the hardware or computer connected to the port.

    Here are some important points to remember.

    1. Connect each of your computers, file servers or other network computers to the hub one by one.

    2. Each computer should be connected to the hub with a straight-through, RJ-45, Category 5 cable. Each cable should be less than 100 meters (328 feet), in length. Ready-to-use network cables of various lengths can be purchased at most computer stores. See page 11 for cabling specifications.

    3. When connecting a computer to a hub, either the computer or the hub must be powered OFF. If both the computer and the hub are turned on while the connection is completed, the network will act erratically and you must reset the hub (see page 10).

    4. If the Uplink port is in use (connected to another hub, etc.), the port next to the Uplink port must remain empty and unused. As in most hubs, the Hub’s Uplink port and the port adjacent to it are joined together inside the hub, and one cannot be used while the other is in use. If you have an 8-port hub, for example, port 8 cannot be used if the Uplink port is in use, and vice-versa. See the next page for special considerations about uplinking.


    Connecting the Hub to Other Hubs or Switches

    Like most hubs, the Fast Ethernet 10/100 hubs can be uplinked to 10Mbps or 100Mbps hubs, switches, or broadband Internet devices. The back of each hub has an Uplink port for this purpose.

    If you are connecting the hub to a Fast Ethernet hub or switch, remember that Fast Ethernet rules only allow two hubs to be connected together, or uplinked, within a single network.

    To uplink the hub, simply connect a regular straight-through Category 5 cable from the hub’s Uplink port to any regular network port on the hub or switch being uplinked. The Hub will automatically determine the optimum speed of the device being attached to it.

    Remember that while the Uplink port is in use, the port adjacent to it must remain open, and should not be connected to any cable or computer. See page 4 for important limitations when connecting hubs.

    The Distance Extender Feature

    The 5-Port and 8-Port 10/100 Hubs have a special distance extending switched uplink feature. When all ports on the hub are running at 100Mbps, the switched distance extender feature will turn on automatically.

    When the feature is active, your uplink distance increases to 100 meters instead of the usual 10 meters. So, if ports 1 through 4 on the 5-Port model, (or ports 1 through 7 on the 8-Port model), are running at 100Mbps, your uplink port is capable of transmitting data to another 100Mbps hub up to 100 meters away. Remember that the port next to the uplink port must remain open when connecting to other hubs or switches.

    There is no way to turn on the distance extender feature manually. The feature turns on automatically only when the ports are all running at 100Mbps.

    Connecting to a Cable Modem or DSL Modem

    If you have a cable modem or DSL modem in your home or office, and you want to share it across your network, it’s very easy to do with the 5-Port or 8-Port 10/100 Hub.

    Most broadband devices translate your Internet connection into a 10BaseT Ethernet connection. If you have a cable modem or DSL modem that uses a 10BaseT connection, simply attach your device directly to the Uplink port on your Network Everywhere hub. Use a regular straight-through cable. Do not use a cross-over cable.

    If you have an internal cable or DSL modem, or if your broadband device does not use a 10BaseT Ethernet connection, talk to your service provider about switching to a sharable device with a 10BaseT connection.

    In order to set up your broadband service so that your entire network can share the connection, talk to your service provider. They should be able to help you configure your networked PCs for a small fee.
