RJ-45 (10BASE-T/100BASE-TX) Port Connectors

The RJ-45 port connectors (Figure E-1) are wired as MDI-X ports to connect end stations without using crossover cables. (See “ MDI and MDI-X Devices” on page E-2 for information about MDI-X ports.) For 10BASE-T connections, use Category 3 (or higher) UTP cable. For 100BASE-TX connections, use only Category 5 UTP cable.
