two connectors would cancel one another, and the hub-to-hub connection would fail.)

Thus the rule for making a hub-to-hub connection with twisted-pair cable is as follows:

To make a hub-to-hub connection with a straight cable, Uplink must be selected at one end of the cable, and Uplink must not be selected at the other end of the cable.

To make a hub-to-hub connection with a cross-over cable, Uplink must not be selected at either end of the cable.

To connect the Ethernet Hub to a thin coaxial cable (lOBase2 cable, also known by its wire- standard name, RG58A/U, and a variety of other informal names), first twist a BNC T-connector onto the rear-panel BNC connector of the Ethernet Hub. Then twist the shell of the cable’s connector onto either leg of the BNC T.

If the thin coaxial cable continues on to other nodes, then twist the shell of the continuation cable onto the remaining leg of the BNC T. If there is no continuation (the Ethernet Hub is at the end of the coaxial cable), then it is necessary to twist a 50-ohm terminator onto the remaining open leg of the BNC T.
