Crossover Cable
If you do not wish to use a repeater or switch to connect servers and
workstations together, you can use a crossover cable. A crossover
cable connects the transmit, or TX, pins on one end of the cable to
the receive, or RX, pins on the other end of the cable. Crossover
cables connect workstations and servers directly, without the use of
a repeater or switch. You will generally need to make your own
crossover cables, or custom order them from your supplier. Cables
for 100BASE-TX use two pairs (pins 1, 2, 3, and 6). Cables for
100BASE-T4 use four pairs (pins 1 through 8)
Note:
All pins must be connected even if they are not used to
transfer data.
