Connect Broadband Internet Gateway to Hub
aenlle May-15-01 07:22 AM
The Sohoware BIG allows Internet sharing through its ethernet ports which works great with DSL. I want to expand my little network with another hub.

If I use a straight through ethernet cable from the Uplink port on the BIG (switch set to uplink) do I just plug into the standard port on the hub or does it plug into the hub's uplink port?

There is no big mystery about the difference between an uplink and a regular port. Each Ethernet interface has two transmit pins (+ and -) and two receive pins (see the top of http://duxcw.com/digest/Howto/network/cable/cable5.htm). The transmit pins at one end of a cable have to be connected to the receive pins at the other and vice versa. An uplink port does not crossover the transmit and receive pins and regular port does. If two hubs/switches (http://duxcw.com/faq/network/hubsw.htm) are connected together with a straight-thru cable than one end must crossover (regular port) and one end must not (uplink port). If a crossover cable is used to connect them, then the ports at both ends must be the same kind of port. If a straight-thru cable is used to connect them, then the ports must be different. A PC can be connected to an uplink port with a crossover cable and to a regular port with a straight-thru cable. Also, be aware that many hubs/switches share the uplink port with one of the regular ports, usually port 1. Both ports will not work if they both connected at the same time. Finally, many hubs and switches have a switch associated with the uplink port that can switch the port between uplink and regular port configurations. An Ethernet switch is better than a hub and costs about the same. Try to get one without a fan. Larry

Thanks for clarifying the matter.
