If any of these ports are given a fixed configuration, for example 100 Mbps/Full Duplex, the ports
operate as MDI-X ports, and straight-through cables must be then used for connections to PC NICs and
other MDI ports.
Figure 1 Cable Diagram
Pins 1 and 2 on connector “A” must be wired as a twisted pair to pins 1 and 2 on connector “B”.
Pins 3 and 6 on connector “A” must be wired as a twisted pair to pins 3 and 6 on connector “B”.
Pins 4, 5, 7, and 8 are not used in this application, although they may be wired in the cable.

Crossover twisted-pair cable for 10 Mbps or 100 Mbps network
connection
The Auto-MDIX operation of the 10/100 ports on the switch also allows you to use crossover cables for
all network connections, to PCs, servers or other end nodes, or to hubs or other switches.
If any of these ports are given a fixed configuration, for example 100 Mbps/Full Duplex, the ports
operate as MDI-X ports, and crossover cables must be then used for connections to hubs or switches or
other MDI-X network devices.
