A crossover cable is a twisted-pair cable in which the wires have been crossed. The figure below shows the pin assignments for an Ethernet or Fast Ethernet crossover cable:

NOTE: The port 1 1X jack shares its circuitry with the Uplink jack. If you connect a hub to the Uplink jack, you cannot plug anything into the 1X jack. And the reverse is also true; if any- thing is plugged into the 1X jack, the Uplink jack cannot be used.

When uplinking two dual-speed or Fast Ethernet hubs or hub stacks in this fashion, the maximum distance between any two end-stations in a collision domain is 205 meters. If the length of the longest hub to end-station connec-
