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.
